What can and cannot be washed in the dishwasher: features of washing dishes from different materials

Safety

The dishwasher is a fairly safe unit. But following a few conditions will help you avoid possible unpleasant consequences.

1. Again, wait for the dishes to cool before taking them out of the machine.
2. When installing the PMM, remember the mandatory grounding of the device.
3. In the event of a malfunction, read the decoding of the error code shown on the device display. If it is impossible to fix the breakdown on your own, disconnect the machine from the mains, turn off the tap and call the master from the service center.
4. Do not install the dishwasher near the stove and radiators.

Starting the dishwasher

After loading all the dishes in the PMM, a washing program is selected. Much depends on the manufacturer and specific models of the device. Usually there are 4 types of programs:

• rinsing;
• washing lightly soiled and glassware at +45 degrees;
• washing dishes with medium soiling at a temperature of +50 degrees;
• washing of strong pollution, pots and pans when water is heated to +70 degrees.

The first rinse mode is used for heavily soiled items with adhering pieces of food. Then, under the pressure of hot water, they are washed off and the overall quality of laundering improves.

After completion of work, the dishwasher is unloaded from the lower compartment. This arrangement will prevent water droplets from falling onto the utensils below, since the liquid still remains, even though modern devices are equipped with a drying program.

"Homemade" cleaning recipes

If you do not use the above substances, the internal elements of the device will eventually become covered with rust, fungus, mold. Along with purchased products, you can use homemade products. For the mixture you will need:

• Soda - 200 g;
• Peroxide - 1.5 tbsp. l.;
• Essential oil - 10 drops.

Balls are molded from the resulting mixture and placed on the shelf below.

Mix 400 g of vinegar and a spoonful of washing gel. This composition is placed on the top shelf and the washing program is started. You need to use the vinegar mixture occasionally, otherwise the car will stick to the hard-to-remove vinegar smell.

And yet, experts recommend using special equipment, fortunately, they are in abundance on store shelves. For example, Finish Rinse or Calgonit Fusion Power. After pouring the dose into the appropriate compartment, wash for at least an hour and a half.The temperature must be 60 °C.

What dishes can not be put in the PMM and why

Cutlery will be hopelessly damaged if made from:

• aluminum;
• cupronickel;
• porcelain;
• cast iron;
• crystal;
• tree;
• clay;
• plastic;
• covered with enamel;
• electrical appliances.

Overview of "prohibited" materials

Aluminum utensils.

521491857

Pots, frying pans, spoons, mugs, a cauldron, an exhaust filter, an aluminum alloy grill grate under the influence of high temperatures, dishwasher aggressive powders (tablets) acquire an unpleasant dark gray coating that stains hands, countertops, everything around. Therefore, it is better not to take risks and organize manual cleaning of aluminum products with a mild detergent.

Melchior.

Most often, exquisite cutlery is made from cupronickel, resembling silverware: spoons, forks, knives. Washing in the dishwasher is strictly prohibited. From hot water, powders oxidize, becoming covered with black spots.

Porcelain.

Antique porcelain, porcelain services covered with glaze, gilding, cannot be washed in a dishwasher. Delicate, manual care is recommended.

Cast iron.

In appearance, cast iron is a rather strong, durable metal, but the fragile surface is easily damaged by prolonged exposure to water, hard brushes, and abrasives. The protective layer is erased, rust appears. Wash cast-iron grates, pans with soft sponges by hand.

Crystal.

Solid, Soviet crystal perfectly tolerates any regime, the main thing is to choose a special tool. Some powders, capsules may react chemically with lead, which is contained in crystal glasses, decanters, vases (dishes may turn yellow). Carefully read the instructions of dishwashers, choosing the right one for your dishes.Modern glasses made of the finest crystal are dangerous to wash in the dishwasher. They can break from vibration, strong water pressure. Fragile glass is loaded into the PMM only if the model is equipped with special latches and a delicate mode (for example, Bosch).

Holders will not allow glasses to touch during vibration. The pressure of the impeller jets in the delicate mode is much softer than in the normal mode.

Wood.

Wooden products from dampness, chemistry, high temperature are deformed, delaminate, swell. Do not put wooden boards, spoons, spatulas, mortars, pestles in PMM.

Plastic.

Some plastic containers, refrigerator shelves, children's toys, and other plastic items are sensitive to high temperatures, detergents, and dryer hot air. Therefore, always look for labels that allow washing in dishwashers. If there is no permit sign, it is better not to risk it. This applies to thermos and thermo mugs. To properly organize the sink, you should read the instructions, if there is a “can not be washed” icon, then the flask, the surface of the product are not compatible with PMM.

Enamel.

Under no circumstances should you put enamelware in the PMM. Enamel from automatic cleaning bursts, peels off, metal rusts. Any enameled pan, bowl, ladle, kettle will become unusable after such a procedure.

Electrical appliances.

A blender, an electric kettle, a double boiler (a container from a double boiler), Zepter appliances with electronic elements - deteriorate from a large amount of liquid. Damaged wiring, plug, corrosion of glass, metal, plastic are the consequences of such a wash.Care for household appliances strictly according to the instructions - it will last you much longer.

Clay

Clay pots, other pottery will absolutely "suffer" in the PMM.

Aquarium

Many are concerned about the question of whether it is possible to wash an aquarium in a car. Aquarium manufacturers do not recommend such experiments, as the glass may break.

For which dishes this cleaning method is not suitable

Further, it is advisable to find out which dishes cannot be washed in the dishwasher:

1. Wooden kitchen utensils should only be cleaned by hand. Household appliances can wash natural oils out of it, the products will dry out, and gradually begin to crack.
2. The electric kettle is also strictly forbidden to be placed in the dishwasher: the wires, the LED, the switch placed inside the product will immediately become unusable, and the metal contacts will be covered with oxides. It is better to gently rinse the electric kettle under the tap, avoiding moisture getting inside the case.
3. Acrylic or melamine tableware cannot withstand high temperatures, steam drying, or the influence of any detergents. After such washing, the products do not look very aesthetically pleasing, cracks form on them.
4. The cast-iron frying pan is washed only by hand. This cookware quickly rusts when exposed to water for a long time, and when exposed to chemicals, the non-stick layer can completely peel off. Temperature fluctuations also negatively affect this material.
5. Teflon-coated pans should not be loaded into the dishwasher. Visually, you may not notice damage, but kitchen utensils will lose their factory characteristics.
6. If the label does not state that plastic dishes can be washed in the dishwasher, it is better not to do this.
7. Milky glass after two loads may turn yellow under the influence of high temperatures, aggressive detergents.
8. Products with a vacuum lid cannot be cleaned with a dishwasher: the utensils are deformed and lose their tightness.
9. If you wash aluminum utensils in the dishwasher, a white coating forms on it, which only abrasive substances will help get rid of. Due to oxidative processes, the material can also permanently blacken, which is why it is impossible to wash aluminum dishes in a machine.
10. The lid from the pressure cooker is not recommended to be loaded into household appliances: small particles of dirt can clog the valves, and harsh detergents can ruin silicone or rubber seals. The multicooker bowl will also not withstand the washing process, its inner coating will be damaged.
11. It is contraindicated to load metal graters, strainers, garlic presses. The machine will not cope with washing small stuck pieces of food, and the products themselves risk becoming rusty. It is also impossible to wash aluminum dishes in the dishwasher (for example, colanders).
12. Exclusive hand-painted products are strictly forbidden to be placed in an automatic sink, otherwise the entire decor will be washed off or damaged.
13. Cast iron cookware, grates and other utensils made of this material will soon become rusty after mechanical washing. Cast iron cookware should not be washed in the dishwasher because it forms a protective barrier (a thin layer of fat that appears after the first cooking of the dish). In the typewriter, this layer is destroyed, so you cannot wash the cast-iron pan in the dishwasher.
14. Silver products are also banned, because under the influence of the chemical composition of the dishwasher tablets, dark spots form on the cutlery.
15. Copper utensils will begin to oxidize and become covered with a coating, which can only be removed by polishing. Therefore, frying pans made of such an alloy and pots cannot be washed in the dishwasher.
16. It is contraindicated to wash damaged glasses and plates, as there is a risk of spoiling the equipment with pieces of dishes that break off during the cleaning process.
17. By placing cans, containers with stickers in the device, the user runs the risk of clogging the drain hole with particles of paper and glue.
18. It is forbidden to wash the thermos and thermo mugs in the dishwasher. The inner part of the vessel under the influence of vibrations is easily damaged and loses its properties. Bacteria and food particles penetrate into the space between the body and the flask, the material begins to rot, which is accompanied by an unpleasant odor.
19. Decorative items - figurines, vases, etc. are also forbidden to be cleaned in this way, since there is no guarantee that they will be durable and will not break.
20. Do not wash knives in the dishwasher. There is a risk of scratching internal parts, plastic mechanisms of equipment. In addition, due to exposure to hot water and steam, the blades will become less durable.

Often housewives do not know if it is possible to wash baking sheets in the dishwasher. Meanwhile, many manufacturers include special nozzles in the package that allow you to conveniently place these bulky kitchen utensils inside the device (sometimes this will require you to remove the top tray designed for cutlery).

Dishes made of wood and plastic

What kind of wooden objects and utensils do not people shove into the dishwasher, and then grab their heads, not understanding what happened to their favorite cutting board, rolling pin or wooden spoon. Meanwhile, everything is explained simply. The tree tends to swell from prolonged exposure to water, the wood fibers are saturated with moisture and increase in size, respectively, the wooden product itself increases in size. When a wooden object dries out, the fibers shrink sharply, and the strong bond between them is destroyed.

What is the result? And as a result, the wooden object is deformed, ugly cracks appear on it, it loses its appearance and “begins to ask for the trash.” Wooden dishes can be saturated with moisture, being in water for only 30-40 minutes, and in cold water, and if the water is hot, the time is greatly reduced. In a dishwasher, washing programs can last up to 210 minutes, and what do you think will happen to a wooden object that is poured with hot water with chemicals for more than 3 hours? That's right, it will become completely useless when it dries.

In the dishwasher, as a rule, they try to wash various objects made of wood, and it will not necessarily be dishes, but in most cases this is it, for example:

• rolling pins;
• cutting boards;
• pestles;
• blades for pancakes;
• wooden Toys;
• spoons;
• bowls and more.

Plastic dishes can only be washed in the dishwasher under certain conditions. In particular, if the dishes are made of heat-resistant plastic and there is a mark on it that allows automatic washing. Otherwise, plastic dishes and other plastic items cannot be pushed into the dishwasher. In particular:

1. disposable plastic cups, plates, forks, spoons;
2. plastic plates without any marks;
3. pungent chemical-smelling plastic toys;
4. plastic objects with glued elements.

What else not to put in the dishwasher

Restrictions on automatic washing do not only apply to aluminum, plastic and wooden items. What dishes and other items should not be put in the dishwasher, especially if the machine has a limited choice of washing modes?

• Things made of fine porcelain. In general, it is not worth subjecting to automatic washing any other porcelain, but especially fine porcelain. Porcelain from hot water can crack quite quickly, and if you still turn on the turbo dryer, then it will definitely come to an end.
• Cast iron cookware. After the first wash with a cast-iron product, there may be nothing, especially if the products are large. But after the second or third wash, you will see why it had to be washed by hand. Cast iron cookware will corrode and lose its appearance.
• Crystal tableware and souvenirs. Crystal also doesn't handle the "dishwasher date" well. Not only can micro-scratches remain on it during the washing process, it also cracks from temperature changes.
• Dishes with a vacuum lid. Plastic containers, mugs, saucepans with a lid capable of pumping out air, creating a vacuum inside, should also not be put in the dishwasher. The fact is that plastic containers undergo some deformation from automatic washing, the eye may not notice it, but this leads to the fact that vacuum dishes lose their tightness and air penetrates into it.
• Sharp kitchen knives.As a general rule, so that the knife does not become dull for a long time, it must be washed very quickly under running cool water. If you hold it for 5-7 minutes in hot water, sharpening will become noticeably worse, and if you constantly wash it in hot water, you will have to sharpen it once every 2 days. At the same time, it is clear that in the dishwasher, where the dishes are rinsed in hot water for a long time, there is nothing for a sharp knife to do.

• Copper items. Copper does not tolerate prolonged contact with hot water and detergent. From such an aggressive environment, the copper object darkens and loses its appearance.
• Thermo mugs and thermoses. If the manufacturer of a thermal mug or thermos expressly allows washing its product in a dishwasher, then you can safely wash it. In all other cases, wash the thermos and thermo mug by hand.

As part of the article, we tried to answer the question of which dishes should not be washed in the dishwasher. Of course, in reality, the list of “forbidden” items is much wider, but the main thing is to understand the principle and not make mistakes fatal for things in the future.

Thank you for your attention!

Reasons why you should not put aluminum in the PMM

Aluminum is a fairly active metal that reacts with many substances and even with water, under certain conditions. Such conditions are created inside the dishwasher. On the surface of this metal there is a dense oxide film, which dissolves well with alkalis. Many detergents for dishwashers contain alkalis, thanks to which the dishes are washed without physical impact.

So, under the action of alkali in hot water, an oxide film is removed from the surface of aluminum dishes.As a result, aluminum gets the opportunity to react with water, which leads to the destruction of this metal and the appearance of a dark coating on its surface. If the dishes are exposed to such an effect for a long time, then it will not only be dark, but will also begin to collapse. Some note that after washing the dishes at 35 degrees, nothing happened at all, but we warn you again, after several such washes, the dishes will still darken. And possibly forever.

Hand dishwashing detergents are less aggressive, so we don't notice any change with aluminum cookware. However, with prolonged use, the darkening effect still appears. So, let's conclude, aluminum dishes should not be put in the dishwasher, because:

• she loses her appearance, acquiring a dark coating;
• it is not safe for health.

What to do with darkened dishes?

With why it is forbidden to wash aluminum in the dishwasher, everything is clear. But after all, not many people remember chemistry lessons, not everyone reads instructions for dishwashers, and not all instructions contain a note that aluminum dishes cannot be washed, and some even accidentally put such products in the tank. On thematic forums, users write about how they were spoiled:

• pots;
• frying pans;
• garlic press;
• spoons;
• meat grinder parts.

Therefore, the question arises, is it possible to return the former shine and attractiveness to aluminum dishes? Everything is not so simple and will depend on how much the thing has changed color. The protective layer of the metal is not destroyed immediately, the hotter the water and the more alkali in the detergent, the faster the dishes will darken and become covered with a gray coating. Of course, spoiled dishes should be thrown away, but sometimes this is not possible, especially if these are parts from a new meat grinder. How then to remove plaque?

Only manual cleaning with special tools will help. But boiling with soda and powder will only aggravate the situation, so in no case do this. Nitric, sulfuric and other acids can help in the fight against plaque, but we will not describe this method, since it is not safe and can lead to irreversible consequences. Acetic and citric acid are unlikely to have the necessary effect, because they are weak. Here's what to try:

• cleaning and polishing with GOI paste for final polishing. It is necessary to apply the paste on a piece of felt cloth and rub the darkened product;
• polishing with a special French-made paste Dialux;
• treat the darkened products with a HORS rust converter for cars (use as a last resort), and then rub with one of the above products.

What other dishes should not be washed in the dishwasher?

Not only aluminum dishes can be damaged in the dishwasher. And if such dishes in some cases can be, and indeed need to be replaced, then you can’t just part with another

Therefore, pay attention to what other products should not be washed in the dishwasher:

• dishes made of wood or with wooden parts - from a long stay in water, such dishes will swell and crack;
• silver and cupronickel dishes - just like aluminum dishes, they can darken and lose their attractive appearance, which is not so easy to return;
• Teflon-coated pans, if there is no permit sign - during the washing process, unprotected Teflon becomes dull, which leads to food burning;
• knives - under the influence of hot water, the knives become very dull;
• bone and expensive china - can darken and lose their luster.

The most important thing when washing dishes is to observe the temperature regime and the rules for arranging dishes. You can even ruin ordinary dishes if you wash them in too hot water with concentrated detergent.

So, aluminum cookware is the number 1 prohibition for the dishwasher. If you do not want to spoil the details of a new meat grinder or your favorite aluminum frying pan, then do not experiment on the advice of other users, they say, until you try it yourself, you will not know. In this case, everything is quite clear even without experiments, learn from the mistakes of others.

How often to wash the dishwasher?

Prevention is the key to the stable operation of equipment. If you do not follow it, accelerated scale formation, the appearance of unpleasant odors, and premature wear are possible. Recommended maintenance schedule:

• After each wash, wipe the sealing rubber and the inner surface of the chamber with a dry cloth.
• Wipe the control panel and door weekly with a damp sponge and soapy water. You also need to rinse the filter with water.
• Have a "bath day" every month with citric acid.

Women are especially happy with the dishwasher. The hostesses love to cook, treat their family with pickles, but then they have to dismantle the mountains of dirty dishes. Men are unpretentious in food and do not tend to use extra plates, so for them a dishwasher is an ordinary kitchen device, and not a panacea for routine.So it is women who are more likely to sound the alarm when using this technique. Having received an assistant at their disposal, the ladies are in no hurry to understand her device - a pump, a hose, a drain ... Fi, how uninteresting! Therefore, any breakdown becomes for them:

• a - surprise;
• b is a disaster.

There are many ways to solve and even prevent possible problems. The secret of success lies in the regular washing of internal surfaces and cleaning the filters.

What other items are undesirable to clean in the dishwasher

Some of the plastic products are also desirable to wash by hand. So, containers, plastic children's dishes, disposable tableware during automatic washing can be deformed. But products made of heat-resistant plastic are suitable for cleaning in a dishwasher.

Containers, plastic children's tableware, disposable tableware may be deformed during automatic washing.

It is undesirable to use in the dishwasher and wooden items, such as cutting boards. With prolonged exposure to water and heat treatment, the structure of the tree is damaged, it swells, and cracks may appear.

With prolonged exposure to water and heat treatment, the structure of the tree is damaged, it swells, cracks may appear. Boards coated with a water-repellent substance can be subjected to automatic washing, if provided by the manufacturer.

Not all pots and pans can be washed in PMM. So, objects with wooden handles should be washed by hand. Teflon-coated pans are dishwasher safe, but also easy to clean by hand. Their manual processing will help to extend the life of the product.

Items with wooden handles should preferably be washed by hand.

Also, you can not clean elegant wine glasses and glasses made of thin glass in the dishwasher. They can easily crack under strong automatic pressure. Do not load new products with labels into the machine. The paper may separate from the dishes and get caught in the dishwasher, causing breakage.

Glasses can easily crack under strong automatic pressure.

Cutlery such as forks and spoons are dishwasher safe. But it is better to wash the knives by hand, because prolonged exposure to high temperatures contributes to their blunting. Under the pressure of the liquid, the knife can also break, and its blade can damage the rest of the dishes or the appliance itself.

It is better to wash knives by hand, because prolonged exposure to high temperatures contributes to their blunting.

Before using pmm, check which dishes can be washed in the dishwasher. So, products made of heat-resistant glass, stainless steel, heat-resistant plastic, glass-ceramic dishes or items with an enamel coating, silicone baking dishes are ideal for automatic washing. Before washing any item, check the label for the manufacturer's recommendations. But ceramic, silver, porcelain or crystal, clay and wooden dishes should definitely be washed by hand so as not to disturb their functionality and appearance. It is also worth considering that different modes of operation of the appliance are recommended for different types of dishes.

How to arrange

The quality of washing household items, dishes depends on their correct location in the PMM:

1. Start loading from the bottom of the working compartment. Here the water temperature is higher than at the top.
2. Glassware is placed upside down.
3. Large plates are placed on the sides, and small ones in the center.
4. Cutlery with long handles is folded horizontally, alternating with other items.
5. Frying pans are placed vertically so that the handle rests on one of the plates.
6. Trays, trays are placed along the edge of the basket below.

Remains of food must be removed from plates, trays, pots before washing. If there is a lot of pollution, then it is better to fill the machine halfway.

What are the steps involved in washing dishes in a dishwasher?

Most often, manufacturers describe in detail the process of the device. But it is written in a dry language, so not everyone can get through the technical jungle and find out exactly how the unit works. In fact, everything can be explained in words that will be understood even by people far from the world of engineering.

The washing process consists of the following steps:

1. Loading. First you need to place all the dirty dishes inside the appliance. In this case, knives, spoons and forks should be laid strictly in a horizontal position. In most models, a special tray is provided for this.
2. Inclusion. You should set the desired mode and press the "Turn on" or "Start" button on the device panel. After switching on, the machine will begin to draw water, which will fall into the compartment intended for this.
3. Put the detergent into the dispenser. After starting the unit, it will begin to flow into the water and mix with it, creating a soapy solution. It can be a special gel, powder or tablets. When the machine collects the required amount of liquid, it will start heating the water.
4. If the dishes are covered with a thick layer of fat or burnt pieces of food are stuck to its surface, first set the “Pre-soak” mode. After its activation, the cleaning solution will be sprayed in small quantities on the kitchen utensils.
5. After that, the "Primary rinse" mode will turn on. In this case, the remnants of food will be washed off under the pressure of the water jet. In this mode, water is supplied through a special sprayer, which is located under the basket for kitchen utensils.
6. Most models have a "Re-rinse" function. When activated, the machine will use the water collected after the first rinse. The option will allow you to save water resources, and, accordingly, money. At the end of the repeated rinse, the liquid will drain after a corresponding signal from the control panel. Then the unit will again collect a small amount of rinsing liquid, which will merge into the sewer system.
7. To achieve the desired result, the dishes should be rinsed again. So the device will completely remove pieces of food and household chemical residues.

Modern units are equipped with the function of drying kitchen utensils. Depending on the specific model, the process can be natural or forced. In the first case, the dishes dry out gradually under the influence of the convection mode. In the second, a hot jet of air is forced into the unit.

What dishes can not be washed in the dishwasher?

All manufacturers and experts believe that under no circumstances should you wash in a dishwasher:

• Wooden kitchen items. Cutting boards, wooden spatulas, spoons.Also, you can not wash in the car and items that have wooden inserts and decorative elements. Wood does not tolerate temperature changes, and most of all does not tolerate a sharp increase in humidity. This causes the wood to swell and crack. Lacquer will peel off it. And glued elements can fall off after the first wash. From temperature and moisture, the adhesive loses its properties.
• Crystal glass does not tolerate automatic washing. Most varieties of crystal deteriorate badly if washed at temperatures above 50 degrees. From this, it can become covered with small cracks, fade, change color and transparency. It is allowed to wash crystal only in those machines that have a separate program for this. Crystal is best washed by hand and immediately wiped with a waffle towel.
• Silver should not be washed in a dishwasher such as Bosch. Expensive silver cutlery does not generally contact well with other types of metal. The fact is that water partially dissolves any metal. This happens at the molecular level. A person will not feel it, and the silver spoons will immediately darken or become covered with an unpleasant coating. Chemical cleaning will also be required. It is impossible to wash silver in PPM.
• Decor items (regardless of purpose). Any decorative items are not originally intended for the usual use. Therefore, no wear-resistant materials are used in their manufacture. Therefore, washing in the dishwasher can ruin them.
• The thermos should not be washed in the dishwasher. The thermos has a capricious design and if its thermal insulation picks up moisture, then the thermos will deteriorate. It should only be washed by hand.
• Kitchen knives do not tolerate automatic washing and prolonged exposure to high temperatures.If you need to disinfect the knife, then it is better to pour plenty of boiling water from the kettle or use a disinfectant. But don't put it in a dishwasher like bosch.
• Non-stick, ceramic-coated pans like Tefal cannot be washed in the dishwasher! Otherwise, you risk spoiling the pans, over time the coating will thin out, or it may bubble. Many complain: “I washed the Tefal pan in the dishwasher, and now everything sticks to the bottom!”
• Cast iron pans, cast iron cookware, and cast iron grates should be washed by hand. In the dishwasher, cast iron loses its appearance and can begin to rust. If the pan is rusty, it will rust all the time. Cast iron tends to be covered with a thin film of fat from food. This saves him. Manually, this film is not washed off, but the dishwasher will easily remove it, and after the dishwasher the surface of the cast iron will remain unprotected.
• Do not wash aluminum utensils in the dishwasher. Aluminum pans and milk jugs can become covered with a white, unpleasant coating.
• The knives and mesh of the meat grinder may begin to rust after entering the dishwasher. After the first wash, the white knives from the meat grinder will immediately turn black (this is oxidation). Do not be surprised that the meat grinder or duckling has turned black. The blackened meat grinder will then have to be cleaned with an abrasive.
• Ugly dark spots appear on copper products after automatic washing. Gradually, the entire surface of the product will darken in this way. This is also oxidation and can only be removed by polishing.
• Multicooker tanks are strictly forbidden to be washed in the dishwasher. From detergent and hot water, the coating of the internal cavity may be damaged, and the part will become unusable.
• Baking trays have a bad effect on the drains and filters of the machine. If the pan itself is not damaged, the dishwasher itself will suffer.
• Do not wash various strainers, graters and other small items in the car. Contaminants are not washed out of them, and the sharpened elements of the grater are dulled.
• Porcelain and bone china with inlays of gold-colored materials may be damaged. Golden elements from automatic washing fade, and subsequently completely washed off.

Now that we have figured out what cannot be washed in the dishwasher, let's consider what can be washed there.
