How not to get bogged down in fat: we clean the ventilation and exhaust hood in the kitchen

What harmful substances are released in the kitchen during cooking

The kitchen is the room where households spend most of their time. According to statistics, a person is on it every day from 3 to 8 hours.And at the same time, he breathes in air that cannot be fresh and clean by definition, because food is cooked in the kitchen, fried, steamed, boiled. A rare kitchen can boast of spaciousness and convenience. Typical Soviet buildings were built in such a way that a minimum area was allocated for the kitchen. Like, cooked food - and free. With poor ventilation in ordinary and especially in small kitchens, the air is heavy. Keeping the window permanently open is not possible. But in fact, the air in the kitchen is not only not ideal in composition, but also contains a lot of carcinogenic substances. Among them, the most dangerous are the following:

1. Radon, a radioactive gas that enters apartments with natural gas that runs stoves. This gas causes lung cancer along with smoking. It should not be forgotten that a person receives 75% of all radioactive radiation not from the activity of the sun and not from staying in radioactively contaminated territories, but from radon. There is even more radon in the bathroom than in the kitchen, because radon enters apartments through tap water. By equipping faucets with good carbon filters, human exposure to radon can be virtually eliminated. But with regard to gas, the only method is to ventilate the room and have a well-functioning exhaust hood.
2. Aldehydes: formaldehyde, acrolein, ammonia, acrylamide, polycyclic aromatics, saturated and unsaturated acids. They are released during the frying process. And if droplets of water fall into the hot oil, a micro volcanic eruption occurs from the oil-water mixture. Droplets "shoot" high and far, settling on the ceiling, walls and furniture.Over time, dirt and dust adhere to them, emitting carcinogenic volatile substances.
3. Carbon monoxide. The concentration of this substance should not exceed 2%, and a family of 3 people consumes 1 m3 of gas daily, i.e. the concentration of carbon dioxide is almost 4%. Without a good exhaust, you can easily get poisoned by the combustion products of a gas burner.
4. Increased humidity. The air of an average 9m2 kitchen contains three glasses of water in the form of vapours. Ideally, air humidity should not exceed 60%. a well-functioning hood can help with this.
5. Microorganisms. Microbes and bacteria thrive in warm, humid environments. That is why the kitchen should be cleaned as often as possible. And to ensure high-quality outflow of air into the ventilation shaft.

Hoods are different in structure and functional device. Depending on the type of exhaust device, there are exhaust and filter hoods. In the first case, the hood takes air from the kitchen and “carries” it into the ventilation shaft. Filtering types of hoods are equipped with several layers of carbon and grease filters that purify and disinfect the air, returning it back to the room. This is a more complex device. Filters are changed every 3-6 months.

To clean them, you must first disassemble.

1. Disconnect the hood from the power supply. Remove the bottom cover, which is installed parallel to the gas burners. Unlatch the latches and pull the cover down, it can be easily removed. If the grille is attached with bolts, unscrew them with a screwdriver.
2. Take care of filter extraction. They are fastened with clamps or inserted into grooves.
3. Remove the pipe containing the filter. It also needs to be washed with a grease remover.If the design of the pipe hood does not suggest, simply remove the air filter and replace it with a new one.
4. Prepare a grease remover in advance. It can be a regular dishwashing gel. Apply the product to a sponge and rub it on the surface of the grate until foam forms. Place the rack in the soap solution. If the contamination is severe, wipe the surface with citric acid. In extreme cases, when the grate has not been cleaned for a long time, the fat has dried up and does not lend itself to conventional means, use a pipe cleaner. However, remember that excessive use of chemicals will damage the metal surface of the grate.
5. The air filter does not always need to be cleaned. It is best to throw away the old one and replace it with a new one. If you decide to just clean the filter, you can put it in the dishwasher or wash it by hand.

Checking the operation of the air duct

Cleaning the ventilation shaft takes a little time - the main thing is to do it regularly

The working status of the channels is checked in the following order:

• gratings on vents are dismantled;
• dust, dirt deposits, fatty deposits are washed off them;
• gratings are put in place;
• a transom or window opens in the kitchen;
• a paper sheet measuring 10x10cm is applied to the outlet;
• the situation is assessed: adhered paper held by the natural force of the air is an indication of the good performance of the system.
• similar manipulations, but already with open doors, are carried out with ventilation ducts in the toilet and bathroom.

Knowing how to clean the ventilation in the apartment yourself, you can avoid unnecessary work. First, all available vents are audited, one after the other, each separately.The degree of deviation of the paper sheet in each case is analyzed. If, as you move forward, the angle of its deviation begins to change, the blockage is in the middle of the ventilation duct.

Applied tools and equipment

We offer to consider a set of cleaning equipment from the well-known Finnish manufacturer Pressovac:

• video camera for internal inspection of air ducts;
• brush machine with electric or pneumatic drive;
• vacuum installation;
• filter unit;
• compressor (used in conjunction with a pneumatic brush machine);
• spray bottle for ventilation system disinfection.

The brush device is a flexible shaft 6-40 meters long, connected to an electric motor or pneumatic drive. The rotating shaft is placed inside a strong shell, a brush of the required shape is fixed at the end.

The vacuum unit is a powerful fan with a capacity of up to 15,000 m³/h that sucks debris out of the channel. Then the flow is sent to the filter machine, where pollutant particles are trapped.

In addition to the main equipment, the kit includes accessories:

• brushes of various shapes and hardness;
• corrugated pipes connecting the units with air ducts;
• plugs for side outlets of ventilation ducts;
• vacuum discs used in round pipes;
• shaped elements and inspection hatches for additional inserts into the channels.

Professional cleaning of ventilation systems

If the ventilation system in an apartment or office is dirty, cleaning specialists will promptly come to the rescue. In their work they use brush machines and vacuum systems. During the diagnostics of the main canals, the scale and nature of pollution are determined. In the process of cleaning the air duct, the brush, rotating at high speed on a flexible shaft, knocks dust, dirt, and grease off the inner walls. All this is immediately removed and collected in sealed bags using a vacuum unit. The length of the brush machine shaft reaches 40 meters! If necessary, disinfection of ventilation ducts and elements of ventilation equipment is carried out. The result of the work of professionals:

• compliance of the microclimate with sanitary and hygienic standards;
• decrease in morbidity;
• increase in labor activity;
• extending the service life of ventilation equipment;
• increasing the level of fire safety.

Types of duct contaminants

Exhaust and supply air ducts and ventilation ducts are the main parts of the ventilation system that require careful maintenance.

Gradually, various contaminants settle on their surfaces, which significantly affect the functioning of the entire exhaust complex.

Even a slight decrease in the working diameter of the duct due to dirt can cause a drop in the draft level in ventilation. When the exhaust is reduced, the air in the room immediately becomes more humid and heavy.

Methods for cleaning household ventilation pipes largely depend on the types of pollutants that have filled the air ducts.

The main ones remain:

• ordinary dust and dirt penetrating into the room and mine from the street;
• rust and other deposits, which over time can concentrate on metal surfaces due to increased levels of humidity;
• fungi and mold;
• plaque from water, which is formed due to the movement of moist air masses or the formation of condensate during a change in air temperature;
• fatty deposits, the source of which is the heat treatment of food products;
• colonies of microorganisms growing in a favorable moist environment.

In specialized facilities, such as laboratories or manufacturing plants, particles of reagents or chemicals may settle on the inside of the ventilation units, which, due to their nature, require a special approach to neutralization and removal.

A separate and rather complex subspecies of pollutants are deposits after a fire or a flood. Combustion products require immediate removal from the mine and air ducts, since the inhalation of these substances is very detrimental to human health.

The consequences of the flood are no less insidious: the abundance of moist air and condensation contribute to the growth of fungal colonies inside the ventilation system.Spores easily move through the air ducts, penetrating into the living quarters, after which the development of mold continues directly in the apartment - on the walls, ceiling of living rooms.

fungus on the wall may be a consequence of long-standing flooding, even with neighbors a few floors away. Mold spores from the air duct can enter the apartment during air circulation and, once in a suitable environment, settle even in a room that was not affected by the flood

Exhaust ducts get dirty more slowly than supply ducts. In the latter, in addition to street dust, allergens are retained, for example, flower pollen, chemical compounds from exhaust gases or emissions from industrial enterprises.

Checking the operation of the air duct

Cleaning the ventilation shaft takes a little time - the main thing is to do it regularly

The working status of the channels is checked in the following order:

• gratings on vents are dismantled;
• dust, dirt deposits, fatty deposits are washed off them;
• gratings are put in place;
• a transom or window opens in the kitchen;
• a paper sheet measuring 10x10cm is applied to the outlet;
• the situation is assessed: adhered paper held by the natural force of the air is an indication of the good performance of the system.
• similar manipulations, but already with open doors, are carried out with ventilation ducts in the toilet and bathroom.

Knowing how to clean the ventilation in the apartment yourself, you can avoid unnecessary work. First, all available vents are audited, one after the other, each separately. The degree of deviation of the paper sheet in each case is analyzed. If, as you move forward, the angle of its deviation begins to change, the blockage is in the middle of the ventilation duct.

Go to filters

Before proceeding with such manipulations, I advise you to read the instruction manual. It indicates the location of the filters, the scheme of installation and dismantling. In addition, each brand provides its own recommendations for the use of cleaning products.

All modern hoods are equipped with grease filters. The frequency of cleaning is specified by the manufacturer. As a rule, this is required every 200-250 hours or every 2-4 months. But in practice it all depends on intensity of technology use.

Smart hoods are equipped with an indicator that will show when the filter needs cleaning. The indication is different. Some models estimate the actual degree of filter contamination, others simply count the number of hours worked.

It is important to follow a few rules here:

• If you neglect to clean the filters, you can bring the hood to breakage. Dirt and grease subject the engine to increased loads, which reduces the period of non-repair work;
• disposable grease filters (so-called mats) made on the basis of polymers, synthetic winterizer, interlining, acrylic should be replaced with new ones. Do not listen to craftsmen who offer to wash them. Even a perfectly washed old filter will not be able to provide a free passage of air flow. This will provoke the occurrence of increased loads on the turbine and increase the risk of breakdowns. In this vein, I advise you to check the availability of replaceable filters at the stage of choosing a hood. Otherwise, then you will have to solve the problem with their search and purchase;
• reusable (permanent) grease filters are made in the form of cassettes and are used during the entire operation of the hood. This requires periodic flushing.In one model, from 1 to 3 cassettes can be installed. The material of manufacture is typical - steel or aluminum. Already after 2-3 months of active use, a thick layer of fat is deposited on the product. It is removed with household chemicals or in the dishwasher.

If you decide to wash the reusable filter in the dishwasher, install it vertically. This will ensure that all contaminants are completely washed away. The washing cycle should be intensive, with a temperature regime of at least 65 degrees. I advise you to refrain from washing dishes along with the filter - let it rinse alone.

If manual cleaning is intended, soak the cassette in detergent diluted in hot water. Use the most common degreaser. More aggressive concentrates can cause darkening of the metal, damage to the appearance of the surface. Soaking is carried out for 15-20 minutes, after which the plaque will begin to move away. Next, the filter is treated with a semi-rigid brush and placed under a stream of hot water with good pressure.

You can clean it with a simple household steamer, steam generator. Here you will need a soap solution and a jet of steam under pressure. In any case, after washing, the filter is thoroughly dried. Only a perfectly dry cassette is placed in the hood.

Again, cleaning or replacing the grease filter should be done regularly. Deposits will reduce the life of the device, moreover, overloading the motor can cause a fire.

If there are charcoal filters in the hood

If your appliance is in recirculation mode, it will need a charcoal filter. It serves to purify the air that enters the room again. It also requires replacement on average once every 3-6 months.In principle, it is possible to combine the cleaning of grease and the change of carbon filters. To reduce the replacement interval, leave the appliance in operation after cooking is completed. 5-10 minutes are enough for excess moisture to leave the coal, it does not form lumps and continues to effectively absorb pollution.

The principle of replacement is quite simple - the old cassette is dismantled, a new one is installed instead. Disposable varieties are not washable and cannot be reused. The degree of saturation of the carbon filter depends on the frequency of operation of the appliance, the frequency of washing the grease filters, the type of kitchen.

If the carbon filter is reusable, the replacement is somewhat different. By the way, such systems can be found only in a couple of manufacturers. They are found on Teka, Elica, AEG hoods. Their service life is about 36 months.

Washing can be done in a dishwasher. As with grease filters, an intensive mode is started with a temperature of at least 65 degrees. Next, the cassette should be dried in an oven at a temperature of 100 degrees. Replacement or cleaning must be timely, otherwise the device will work in vain, the load on the motor will increase.

How to clean the hood grate

Light dirt can be removed from the hood grate without dismantling on site, using liquid detergents. In case of severe clogging, the grate is separated from the body and washed using fat solvents: folk or ready-made professional products.

Scheme of work:

1. Separate the grille from the body.
2. They are placed in a container in which the part can be completely or partially immersed (tray pan, large basin, bath).
3. Spread the prepared agent over the surface so that the grid is completely covered with the preparation.
4. Maintain the recommended time, checking whether the fat leaves the mesh.
5. When the stains have softened, wipe them off with a sponge.

After complete cleaning of the surface from fatty deposits, rinse with running water and dry.

Consider how to clean the hood grate using household appliances:

1. Dishwasher. In the home assistant, you can wash the grate with a slight coating of dirt. If the contamination is strong, the part is pre-soaked in a fat solvent or several washing modes are started in a row with maximum water heating. This is the easiest and most effective way for housewives who monitor the condition of the grate and wash the part regularly.
2. Steam cleaner. The high temperature of the steam (150°C) can dissolve stubborn grease or soften tough splatters to a point where they can be easily wiped off with a sponge. Hot steam removes fatty traces in hard-to-reach places.

If the dirt is old, the methods can be combined to obtain perfect cleanliness.

Ways to clean ventilation ducts

mechanical cleaning

Cleaning is done with scrapers and brushes. Specialized machines with flexible shafts equipped with nozzles are used. Nozzles can be of different hardness to work with different degrees of pollution. Another option is to blow out the ventilation with compressed air.

Sometimes vacuum pumps are used. They are connected to the ventilation outlets and all deposits cleaned with a brush are sucked up by the pump. This is how cleaning happens.

Chemical cleaning

The ventilation system is sealed and chemicals are sprayed inside.They react with fatty deposits, due to which the dirt “sticks” from the surface and is easily removed mechanically or similarly using a vacuum pump.

Combined method

The foam generator pushes hot (at least 60°C) foam into the air duct. The composition contains surfactants that help soften the fat layer, after which it easily exfoliates and is removed mechanically.

Or vice versa - first mechanical cleaning of contaminants is performed, and then wet using a solution with chemical reagents that help to cope with the remaining contaminants.

blasting

Blasting is a chemical spray cleaning procedure. It can be baking soda for gentle blasting, or dry ice for a serious cleanup. The essence of the method is that contaminants are exposed to a reagent in combination with a compressed air stream. The method has a very high efficiency, while not damaging the surface of the duct. The separated dirt particles are removed by means of a vacuum pump.

Disinfection

This procedure is performed after all stages of cleaning the duct. This is not a mandatory measure and the decision on its necessity is made by the state. supervision. Disinfection is carried out if pathogenic microflora is found in the room. The method of disinfection is selected depending on the bacteria found. The disinfectant is sprayed through the duct, rendering it harmless.

Ventilation cleaning is a must

Indeed, with an unprofessional view of external changes in operation of ventilation and air conditioning systems you may not even notice: the fan continues to work, air, albeit in smaller volumes, but enters.Over time, the change in air flow seems to be imperceptible, and the problem does not seem so obvious. And the possible infectious danger is not taken into account at all, since it is not noticeable to the eye. In addition to reducing the set parameters of ventilation operation, there is a risk of ignition of deposits from grease and dust. In addition, on heat exchangers and in the drainage system of air conditioning, pathogenic bacteria and mold multiply and spread in the air of the premises.

What do you need to know before cleaning?

Just wiping the outer part of the case with the buttons does not mean washing the hood. The device will have to be partially disassembled, and in order to do this correctly, you will need to look into the instructions, which indicate all the design nuances and disassembly rules for a particular model. In general terms, the process of preparing the hood for cleaning is as follows:

• de-energize the device;
• unfasten the latches of the top panel (if any) and remove the grease filter. It captures fat particles well, does not need to be replaced - only regular cleaning. The grease filter is usually made of steel or aluminum. The steel version is the best. There are disposable grease filters that are used in the most compact hoods. They are made on the basis of paper, acrylic, synthetic winterizer or non-woven fabric, and need to be replaced every 3-4 months, they cannot be washed;
• remove the charcoal filter, which is equipped with circulation hoods. The carbon filter cannot be washed - it needs to be replaced as it gets dirty. On average, it is changed every 4-6 months.

Flow-type hoods remove the drawn-in air through the ventilation duct to the street. A grease filter is necessary to protect the motor. AT this type of hoods sometimes the ventilation duct needs to be cleaned. Circulating hoods draw in air, clean it and send it back to the kitchen. The cleaner the carbon filter is, the more efficient the process, so don't forget to change it.

What and how to clean hood in the kitchen from fat? It all depends on the degree and age of pollution. Someone will get by with little blood, i.e. the most common detergents, and someone will have to sweat using aggressive chemicals.

Methods for cleaning and disinfecting ventilation and chimneys

To independently clean the walls of the ventilation duct in the kitchen, you can use different tools. Usually, mechanical cleaning is carried out to restore the performance of air ducts.

mechanical cleaning

The most popular way to clean the ventilation system. It involves the use of a vacuum cleaner, a small spatula to remove dirt and a brush with a long handle.

A brush with a long handle will clean hard-to-reach places

Stages of mechanical cleaning

Mechanical cleaning implies a fairly simple process:

• move the stove and kitchen set away from the wall on which the ventilation grill is attached;
• put newspapers on the floor so as not to stain other surfaces;
• provide free access to any section of the duct;
• remove the grate at the entrance to the ventilation duct and wash it with powder and a scraper or replace it with a new one;
• remove debris from the mine by wearing gloves;
• clean dirt and grease from the walls of the channel with a scraper, then immerse the vacuum cleaner hose into the ventilation hole and run it through the ventilation shaft for about 5 minutes;
• wipe with a damp cloth the area that can be reached by hand;
• disinfect and then seal the entrance to the ventilation duct with a grill.

The dirty ventilation shaft is shown on the left, and its appearance after cleaning is shown on the right.

Air circulation

Another way to restore ventilation performance is to improve air circulation. The fact that there are problems with the movement of air masses in the room can be indicated by a piece of paper that is not attracted to the ventilation grate when the doors are fully open in the room. The problem with poor air circulation is usually solved by expanding the gap between the door and the floor to 4 cm.

Air supply

To ventilate the room naturally, open windows and doors. But in winter, you hardly want to renew the air in the apartment in this way. Therefore, you should think about additional ways to supply oxygen to the kitchen and other rooms. For example, air inlet slots can be created in tightly closed plastic windows. Thanks to them, warm and cold air will begin to interact, and the necessary microclimate will be created in the room.

Thanks to special slots in the room, air exchange will improve

Additional exhaust system

If the improvement in air flow has not changed the situation, then it is recommended to install an additional exhaust system in the kitchen. To do this, it is necessary to fix a fan powered by electricity in the ventilation duct.This appliance will add fresh air to the room.

Filter cleaning

There are several types of filters in the hoods, with which they work in different ways:

1. Fat, also called lattice. The external filter can be washed with grease-dissolving agents, also in dishwashers, or cleaned with a steam generator. If the mesh is made of aluminum, alkaline and acid solutions, which lead to stains and streaks, should not be used.
2. A carbon filter is present in recirculation type devices. This type of filter element is disposable and cannot be cleaned. The carbon cassette is taken out of the slot and replaced with a new one. In order for the unit to clean the air well, it should be replaced within the time specified by the manufacturer. The service life can be increased if you do not turn off the device immediately after cooking, allowing it to work for another 7-10 minutes to dry the coal.
3. Replaceable internal grease traps cannot be cleaned. From wetting, they are destroyed, after an aggressive impact, they lose their properties.

Timely change or washing of filters will provide clean air in the kitchen and facilitate the operation of the hood, which will affect the service life.

Duct cleaners

• powerful industrial vacuum cleaners;
• electromechanical equipment;
• reagents and chemical compositions;
• cleaning devices with several filters;
• vacuum installations;
• brush pneumatic units.

Flexible shafts can be used to clean the air passages on their own. They should be attached to a drill or screwdriver.

Ruff can be done independently. You will need 5-6 plastic bottles of the same size, from which you need to cut off the bottom. Then cut the strips with scissors from the bottom to the neck.The width of each should be from 4 to 5 mm. All received blanks should be fixed with nuts, washers, bolts with hats. The weighting agent can be made from lead, an iron can and a steel bar. It remains to string steel pipes 90 cm long on a plumbing cable and screw to the head

In the apartment, a vacuum cleaner or a long-handled broom, a wire with a metal hedgehog on the handle, rubber gloves, and a respirator are also useful for cleaning.

Self-cleaning the ventilation duct

Despite the existing rules, many management companies do not appear in the apartments of tenants for years to check the operability of the ventilation system. Therefore, residents of high-rise buildings are forced to periodically diagnose and clean their exhaust vents on their own.

With small contamination of the exhaust hole, you can achieve results with a conventional brush

The ventilation hatch can be cleaned with minor contamination, but if the dirt has accumulated in it for years, then it is better to call specialists.

Self-cleaning is carried out as follows:

1. Remove the ventilation grilles, clean them well of dirt and dust and rinse under running water.
2. They clean the walls of the ventilation duct, which can be reached. For work, use a metal brush or wire.
3. Clean the hole of debris with a vacuum cleaner.

Actually, this is where all the homework for cleaning the ventilation holes ends. If there is a reverse draft in the duct and the smells of the neighbors are carried into the apartment, you can replace the old ventilation grill with a model with a check valve.

If they did not lead to the desired result, and the thrust in the channel remained at the same level, then there is a blockage in the common shaft. This is the work of special services, which can be called through the Criminal Code.

Licensed companies use professional equipment and special cleaning technologies, which are selected after a thorough examination of the canal and taking into account its current condition.

How to clean individual hood elements

The cleaning process will take no more time than any other processing of kitchen appliances. Regular cleaning of the filter, even in an ordinary soapy solution, will not allow soot to settle on the grill and other internal parts. You can wash the elements of the exhaust hood in the dishwasher. Regular maintenance of exhaust equipment will reduce the cleaning time of all parts of the structure and extend the performance of the unit.

Chassis cleaning

This part of the device is always in sight, so any housewife washes it much more often. For normal wet cleaning, dishwashing liquid is quite suitable. If you want to make the surface more shiny, use a glass cleaner.

If the case has not been cleaned for a long time, a more effective method will be needed. Here are some options:

• spray or liquid for cleaning ovens and stoves;
• composition: 3 tbsp. soda ash, 100 ml of silicate glue, 0.5 tbsp. dissolve the washing powder in a glass of water and apply on the plane;
• rub the body with lemon juice, then rinse.

Button cleaning

It can be difficult to clean the buttons - grease and food debris are clogged in them. To do this, use a toothbrush or cotton buds. You can soak them in the following ways:

• ammonia;
• liquid, which is washed off the varnish;
• hydrogen peroxide.

Be careful not to ruin or damage the buttons

Inner surface

For cleaning, the same substances are used as for washing the body. If a lot of plaque has formed inside, use a liquid to clean the pipes. But be sure to rinse it thoroughly.

air duct

Housewives with flow hoods may sometimes notice a deterioration in the draft of the device. This means that the air duct is clogged and needs to be cleaned. If the pipe is smooth, then it is not so difficult. The sleek round or square duct is easy to disassemble, clean and reassemble. More difficult with corrugated pipes. Sometimes they are easier to change than clean, especially if they have accumulated a large amount of body fat.

Fan and motor cleaning

Before cleaning these items, read the user manual carefully to remember their attachment and location. Then carefully detach and wash the impeller with soapy water. The engine must not be wetted: dust and dirt are removed from it as far as possible, then lubricated. This procedure is carried out once a year.
