Typically, sweat stains become less noticeable, but they still remain.
There is a very simple method that copes well with recently appeared dirt. You need to dilute a little laundry soap in warm water in a basin. Then we put the item for a quarter of an hour before washing.
This method will allow you to get rid of even those stains that appeared on clothes quite a long time ago. It is best to apply peroxide in small quantities to the stains.
After 10 minutes of waiting, you can send your clothes to the wash.
Depending on the degree of contamination, you can try two methods. If the stain is fresh, then use a solution: dilute two spoons of soda in a glass of water, and treat the problem area.
For old stains, it is better to make a paste out of baking soda and water, treat the stain and wait thirty minutes.
