Video on the topic

It all started with a broken vacuum cleaner. For three weeks I was deprived of the joy of cleaning carpets with its help. And in the end, despite all my efforts, they acquired an extremely pale appearance. In the most literal sense of the word, they have become dull and gray. If it were winter, this problem would be solved quite simply - take it outside. I rolled it out in the snow, knocked it out properly, and then please. But winter is far away. Dry cleaning is expensive. In addition, there is carpet in the bedroom, which you simply cannot remove from the house.

I had to worry about finding ways to tidy up carpets and rugs. There are, admittedly, a lot of them

Clean out the dirt

..with salt.

Sprinkle the carpet with fine salt overnight (like “Extra”, and then sweep everything with a broom or brush dipped in warm water. Some additionally rub the salt into the surface of the carpet. This can be repeated several times. Then vacuum the carpet. You can leave the salt overnight. Same role can take on sawdust or large bran.

Sprinkle the carpet with quick brew. Wait until the tea leaves have absorbed all the dust and dirt. Then sweep the carpet with a broom or brush.

But this method is only good for dark carpets. Light hair from tea leaves may become stained.

… using semolina

Fill the carpet with semolina and brush it with a brush. Then vacuum thoroughly.

...with sauerkraut

At first glance, the method, of course, is extremely exotic, but nevertheless, some claim that it works. True, the cabbage should be without adding vinegar. Squeeze it out of the brine and scatter it on the carpet. To remove odor, you can pre-rinse it. Give the cabbage time to absorb the dirt and sweep it out with a brush. If necessary, the procedure can be repeated.

Then let the carpet dry and vacuum.

Cabbage may not remove old stains, but they say it copes well with dirt deposits.

Remove stains...

After you scrape off the plasticine itself, rub the remaining stain with a sponge soaked in a solution of acetone or white spirit (used to thin the paint). You can use an aerosol to clean car covers.

Then dilute any carpet or dishwashing detergent in water, dip a sponge and wipe the carpet with soapy water. . and cool, because over time it becomes soft again.

Finally, vacuum.

If this does not help, then mix 1 tablespoon of ammonia with 2 glasses of cool water and treat the stain with this mixture. Then rinse the carpet with clean water and dry.

An old glue stain must first be lubricated with petroleum jelly, then apply hand disinfection gel, cover with a stack of paper napkins or towels soaked in water and leave for half an hour. Then rinse with warm water and dry.

You can refresh the color of the carpet with potato broth or grated fresh potatoes diluted with water. The starch contained in potatoes will return the carpet to its former freshness.

Basic rules for carpet care

1. Before basic cleaning and removing stains, the carpet must be free of dust.

2. Carpets do not like hot water; too hard brushes; brushing against the grain;... dampness

3. Vanish type carpet cleaners are not suitable for natural fiber carpets. Only for artificial.

4. Carefully clean carpets made from artificial materials with acetone, hydrogen peroxide, vinegar and citric acid, gasoline, kerosene. First, be sure to check how these substances act in some small, inconspicuous area. .

5. Carpet cannot be treated with alcohol, gasoline, acetone or other solvents, but only with warm soapy water.

6. Colored carpets should not be cleaned with products containing bleach, as the colors will discolor.

7. After any stain removal procedure, it is advisable to clean the carpet with a soap solution.

Detergents last generations They can wash off almost any stain, but they definitely cannot return the color of the original shade to faded items. First of all, let's look at the cause of fading (burnout). It's simple - pigments (coloring) under the influence of the rays of our luminary are simply destroyed, which leads to the unsightly appearance of things. It is clear that it will not be possible to restore what is destroyed, but you can slow down the process and slightly (by half a tone) increase the brightness using traditional methods or simply dye the fabric.

To restore color, you can use chemicals, for example - “Color Restorer” Dr. Beckmann

or “The Magic of Color” (Caress, Balm)

There are other manufacturers, the choice of such products is quite large, you can choose according to the type of fabric or price range. It is clear that advertising pictures exaggerate, but still there may well be benefits from such chemicals.

If you categorically do not trust store-bought “chemicals” or want to save money, then you can try traditional methods, for example - make a solution by adding baking soda in the amount of 1 tablespoon (heaped, tablespoon) per 1 liter of clean water, rinse and see the result. For blue-orange-red material, you can use a solution of food vinegar - only 4-5 tablespoons per bucket (8-10 liters) of water. Pink shade fabrics or lilac, can be improved with ammonia solution - a liter of water and a teaspoon (teaspoon) of ammonia. Well, don’t forget about one more small life hack - iron only the back of the item, you should not iron the front part.

For home painting use:

• onion peel. 400-600 grams (depending on the intensity of its shade) of the husk are boiled in a bucket of water for about 30-50 minutes (depending on the desired saturation of the solution), then add table salt, 60-70 grams and place clothes in the container for a day. When you take out the dyed clothes, you will need to rinse them in a vinegar solution, this way you can enhance the effect. This coloring is suitable for brown, marsh green and orange shades, depending on the color of the husk itself - it also ranges from yellowish to dark purple;
• for beige or, for example, sand-colored fabrics, tea leaves are suitable - place in it for at least 5 minutes (the longer, the more saturated it will be). Special durability should not be expected;
• You can try updating black fabrics with a now exotic plant - tobacco; you need to take leaf shag in an amount of about 10-15 grams and pour 1 liter of boiling water over it. Let it sit until it becomes warm, then place the item in it for half an hour, and then rinse it in water (cold and slightly salty).
