What Causes Black Underarm Stains On Clothes

Black underarm stains on clothes are a common problem that can be unsightly and embarrassing. They are caused by a combination of sweat, deodorant, and bacteria.

Sweat is made up of water, salt, and other minerals. When it comes into contact with deodorant, it can cause a chemical reaction that produces a dark residue. This residue can then be transferred to clothing when you sweat.

Bacteria can also contribute to black underarm stains. Bacteria feed on the sweat and deodorant residue, which produces acids that can break down the fibers in clothing. This can cause the fabric to become discoloured or even to develop holes.

To prevent black underarm stains, it is important to:

Wear loose-fitting, breathable clothing made from natural fibers such as cotton or linen.
Use an antiperspirant deodorant to reduce sweating.
Wash your clothes regularly in hot water.
If stains do occur, you can try to remove them by using a commercial stain remover or by making a paste of baking soda and water.

If you have tried these tips and you are still getting black underarm stains, you should see a doctor. There may be an underlying medical condition that is causing the problem.
