Mustard powder

The surfaces of tables, cabinets and stoves quickly become dirty and accumulate traces of cooking, and it is not so easy to get rid of them later. To make your task easier, you need to understand how and how to remove grease from kitchen furniture so that it is quick and effective.

Modern housewives have the opportunity to choose cleaning products from a wide and varied assortment presented in stores. However, more and more often they return to the old and proven traditional methods cleaning using effective means at hand.

The first and main rule that must be followed to ensure that the kitchen always sparkles with cleanliness is that cleaning must be done regularly. So that you don’t have to invent and figure out how to wash old fat in the kitchen, it is better not to start it, but to remove it immediately when it gets dirty. Among other basic recommendations, the most useful are:

1. When starting cleaning, you need to understand what materials the surfaces that need to be washed are made of. Different cleaning products are suitable for different areas of the kitchen and pieces of furniture.
2. Before using a store-bought cleaning product, you must read the instructions for use and follow them.
3. It is better to first try compositions made from available cleaning products on a small area of ​​the kitchen surface, and then wash everything.
4. Any detergents and mixtures must be washed thoroughly clean water, and then wipe the surface dry so that there are no streaks left.

The kitchen is a room in the house that requires daily cleaning, cleaning and hygiene. But wash away many days kitchen plaque much more difficult. Every housewife has encountered this, because you don’t always have the time and energy to thoroughly clean kitchen surface, and grease stains quickly transform into a persistent, indelible plaque.

There are a lot of kitchen cleaning products, but which ones won’t harm your health, won’t damage surfaces, and will also quickly dissolve grease without excessive effort?

The kitchen has a minimum of 3 kitchen unit covers. Each of them requires an individual cleaning method, since the mechanical and chemical effects of cleaning agents leave negative consequences. For example, caustic powder can instantly clean furniture, but corrodes the surface of the kitchen unit, which over time becomes unusable.

Therefore, before purchasing and choosing a product, determine what material your headset is made of. The packaging of detergents always states what surfaces it is suitable for.

Household chemicals are not universal

To avoid damaging the integrity of the surface, you need to apply products with warm water in advance. After a couple of minutes, it’s enough to simply wipe the walls of the headset from grease without friction and the risk of leaving scratches. But be careful with furniture made from cheap materials, fiberboard, which can become saturated with moisture and deteriorate.

If you have purchased a new product to remove grease from your furniture, it is better to test it on a small and inconspicuous area of ​​furniture.

Therefore, you need to select the product individually for each surface, work with gloves, and also rinse the surfaces well with running water and ventilate the kitchen.

For vertical furniture panels, it is better to use anti-grease sprays or gels. This way you can control the application without dripping onto the floor.

Grandma's products for all kitchen surfaces

In Soviet times, kitchen detergents were practically not used. Housewives used to clean the set:

• soda;
• salt;
• acetic and malic acid;
• lemon and its zest;
• mustard powder;
• vodka and alcohol.

Before use, it is necessary to moisten the kitchen furniture panels with hot water to soak. After 5-10 minutes, you can sprinkle the sponge with soda or mustard, and then clean the contaminated areas from grease. If the contamination is severe, then it will not be possible to wash it right away or you will have to put in a lot of effort. Therefore, you can make a porridge from water and the ingredient, spread it on greasy stains and wait a little. You can add acids.

A tincture is made with lemon zest and vinegar and then used for cleaning. The result is excellent, and a pleasant citrus aroma remains.

Another recipe is suitable for cleaning any set. Mix equal parts vinegar and vodka in a glass, add a couple drops of essential oil. Pour the liquid into a spray bottle and spray on dirty surfaces.

Wooden kitchen corner

If the set is made of solid wood, then, oddly enough, you can wash off greasy stains using vegetable oil and soda at a ratio of 1:2. The resulting slurry is applied to the contaminated areas and rubbed with a soft brush, or a toothbrush. The operating principle is as follows: the oil dissolves similar fat and removes it from a dried state. Soda washes away and removes the released oil from the surface of the headset.

Polished surface

Polishing products are both expensive and very harmful to health. Therefore, in order to save money and have a neutral effect on the body, regular potatoes are used. The tuber is cut lengthwise and rubbed onto the surfaces of the furniture. The effect is no worse than from sprays from the store.

Equipment for cleaning and cleaning in the kitchen

Modern steam cleaners are becoming increasingly popular in the kitchen. The powerful pressure of hot steam can clean any surfaces, materials, fabrics without excess detergents. The only drawback is that wooden furniture with thin film coatings and soft surfaces can deteriorate under the influence of high temperatures.

Innovative sponge (melamine)

Melamine sponge is similar to rubber or plastic that shrinks when compressed. The effect when working is similar to when erasing a pencil from paper with an eraser. The sponge wipes away dirt without detergents. Over time, the sponge wears down to small sizes. Quite convenient and, according to manufacturers, harmless to health.

Its best quality is considered to be the removal of traces from permanent markers and felt-tip pens. If children or adults leave drawings and notes on the refrigerator or stove, then such a thing in the household is simply necessary.

Which product to use is up to you. After all, there is no ideal approach to cleaning the kitchen and furniture yet. The main thing is that the overall result is satisfactory, the furniture does not deteriorate, and health does not deteriorate.
