How to Get Rid of Underarm Stains on Shirts

Yellow underarm stains are never a welcome sight. Underarm stains are caused by the reaction of the salts in your sweat to ingredients in your anti-perspirant. The aluminum compounds contained in these anti-perspirants are often the cause of these yellowish stains.

These stains are unsightly, smelly, and can weaken the fabric. Here are the steps to take these nasty stains off your clothing.

Materials Needed

  • Ammonia
  • 2 Aspirin tablets
  • Baking soda
  • Lemon juice
  • White vinegar
  • salt
  • Laundry sponges
  • Laundry pre-treatment
  • One-gallon containers

Preventing Stains

  1. Switch to aluminum-free anti-perspirants. Allow the anti-perspirant to dry before dressing to prevent rub-offs on fabric.

  2. Take actions when perspiration has come in contact with your clothing. Wash or dry clean the garment as soon as possible.
  3. Stop using the dryer when yellow stains begin to appear. Contact with heat can make these stains even harder to remove.

Pre-Soaking Techniques

  1. Before going through your typical laundry routine, soak the soiled garment in an enzyme product designed for pre-soaking.
  2. Alternatively, you may use a paste made from 4 tablespoons of baking soda mixed in a cup of warm water. Rub the paste onto the stain. Use the paste with some vinegar when taking out collar stains.
  3. Vinegar alone may also be used to take out perspiration stains. Pour a small amount of vinegar onto the soiled area. Rub the vinegar into the fabric before washing.
  4. If the stain remains after pre-soaking, do not put the fabric in the dryer or iron it. The stain will become heat-set and quite impossible to remove.

Post-Soaking Techniques

  1. Make a solution out of a tablespoon of ammonia and a cup of water. Apply the solution on the soiled area and air it dry.
  2. Old stains can be treated with one tablespoon of vinegar or lemon juice mixed in a cup of water. Apply onto the soiled area and air dry.
  3. Alternatively, you can use a solution made out of two Aspirin tablets and a cup of warm water. Soak the soiled area in this solution for 2 to 3 hours.
