It’s frustrating to take your favorite T-shirt out of the wash only to find those yellow underarm stains are still there. You might wonder what the heck the stains are, and the likely culprit is a mixture of sweat and deodorant. The chemical reaction between sweat, deodorant and the fabric leave unsightly yellow discoloration on the shirt. Before you kiss your favorite tee goodbye, try one of these remedies to get rid of the yellow stains for good.

Fill a bucket with enough warm water to saturate the T-shirt. Add 1 cup of white vinegar and soak the shirt for three hours. Wash the shirt as usual.

Put two uncoated aspirins into a bowl. Crush them up with a spoon. Add ½ cup of warm water and stir. Pour the mixture onto the yellow stains, wait three hours and launder the shirt as usual.

Mix 2 teaspoons of meat tenderizer with 1 teaspoon of water to create a paste. Wipe the paste onto the yellow stains on the T-shirt and rub it in well. Wait a few minutes, then wash the shirt as usual.

Mix 1 tablespoon of liquid dish soap with 2 tablespoons of hydrogen peroxide. Pour the mixture onto the yellow stains. Scrub it into the fabric with your hands and let it sit for one hour before washing the T-shirt.

Cover the yellow stains with household ammonia. Work the ammonia into the fabric with a rag. Let it sit for 10 minutes before washing the T-shirt.

  • Use ammonia in a well-ventilated area and wear rubber gloves.
  • Wash the T-shirt in the hottest water safe for the fabric and use heavy-duty laundry detergent. Avoid using chlorine bleach, even if the shirt is white, because it can make the yellow stains worse.
