An unpleasant smell in a backpack can appear for a variety of reasons, for example, due to spilled liquids.
It becomes unpleasant to use such a thing, which means that you need to clean the thing as soon as possible to remove the unpleasant smell.
There are several effective ways that do not require serious expenses.
Vinegar
The product should be mixed with water and sprayed on problem areas. Then the item should be dried naturally. It is best to leave the backpack in the fresh air so that the specific smell of vinegar also evaporates.
Alcohol
You can use vodka, which will also eliminate the smell of sweat, spilled drinks, etc. Problem areas should also be lubricated with such a product. After the procedure, it is important to dry the backpack well.
Soap
You should use not the bar of soap itself, but the soap foam. Apply it to the surface with a dry cloth and rub it in.
