Many housewives actively use drugs from the pharmacy in everyday life, as they have high rates of benefit at a low cost.
For example, hydrogen peroxide is known for its ability to deal with difficult stains and unpleasant odors.
Therefore, experienced housewives try to buy hydrogen peroxide for the home in reserve.
To be more precise, the peroxide itself is not poured into the shoes: we use it to treat two cotton swabs and send them into the shoes.
It's worth leaving "surprises" for about 12 hours.
Then remove the cotton wool and evaluate the result: the shoes will no longer be a source of unpleasant odor. This method is very simple and convenient, so it is quite popular.
Many people believe that hydrogen peroxide can be safely replaced with vinegar, using exactly the same method. The effect should be approximately the same.
You can simply add a couple of spoons of soda. This method works well if the smell is particularly strong and powerful.
Litter tray filler also works well, so you can safely use it.
