No matter how much deodorant and antiperspirant you wear, you’re bound to find yourself in a sweaty situation that leaves you with yellowish armpit stains on your clothes. However, you don’t need to be stuck with stains forever. If you use the appropriate methods, you can successfully remove pit stains from your shirts. Fortunately, you don’t have to spend much at all—most materials you need you’ll already have around the house.

Laundry Detergent and Sun

Purchase a liquid laundry detergent that is meant to be used on protein-based stains, such as food stains.

Apply the detergent to the stained area, rubbing it in well.

Let the treated shirt sit for about 30 minutes.

Put the shirt in the washer and launder as you normally would. Refer to the garment label for washing and water temperature instructions. Let it air dry. If this doesn’t work, move on to Step 5.

Rub the stained areas with water to dampen them.

Apply liquid laundry detergent directly to the stain.

Lay the item out in the sunshine. Check on it and spray it with water to keep it damp throughout an afternoon.

Put the garment in the washer and wash with cool water. Let it air dry.

Hydrogen Peroxide

Mix together one part hydrogen peroxide and one part water in a small bowl to create a diluted solution. Hydrogen peroxide breaks down the protein in the perspiration stains. It can also help prevent the stains from darkening over time.

Pour the solution onto the pit stains. Let the garment soak for about 30 minutes.

Launder the garment in cool water in the washing machine. Let it air dry.

Create a stronger solution of hydrogen peroxide (two parts hydrogen peroxide to one part water) if the stain persists. Soak the garment again for 30 minutes and launder in cool water.


Create a vinegar and water solution to use on colored clothing. Mix 1 tbsp. of vinegar and ½ cup of water.

Soak the stained garment in the solution for 20 to 30 minutes.

Wash the garment with cool water and let it air dry.
