This simple trick eliminates the sweat stains on your clothes.

You bought a pretty white blouse, used it a few times, and were careful not to get it dirty, but it still had a yellow spot under your arm? What a pity!

This is a very common situation for those using aluminum-containing deodorants or antiperspirants (specified in the product composition as aluminum hydrochloride, aluminum chloride or aluminum-zirconium complexes).

The sweat itself is transparent, but when it reaches the tissue under the armpit and eventually dries up, the salts, proteins and oils in this region can leave a residue.


This residue is easily removed when the laundry is washed. However, when the body's natural secretions come into contact with the deodorant, they form a yellowish spot.

As the garment is used on a daily basis, this mixture accumulates in the fabric so that the stain becomes impregnated and very difficult to remove with normal washing.

  • 1 teaspoon of kitchen detergent
  • 1 tablespoon hydrogen peroxide volume 10 (3%)
  • 1 teaspoon baking soda
  • 1 old toothbrush

Specified quantities of products are approximate. More or less material may need to be used depending on the size and intensity of the stain in question.

The trick is quite simple: First, mix all the products in one container until it forms a homogeneous paste. Then, with the piece still dry, apply this paste on the stain and scrub with the old toothbrush for about 1 minute.


Let the mixture act on the stain for about 10 minutes and then wash the shirt as usual to regain the white of the fabric. If the stain is very impregnated, you can still rub it with coconut soap at the time of washing.
