how to get rid of armpit stains on shirts

Pit stains are embarrassing, frustrating and costly. Consider the time spent treating pit stains and the money wasted on new shirts, cleaning products, and laundering fees. All that adds up to one big headache. But don’t fret! We’ve got you covered. We’ll explain what causes armpit stains – and how to get rid of armpit stains on shirts.

Armpit stains can be caused by a number of factors, including your sweat and interactions with the deodorant or antiperspirant you use. The most common pit stains are yellow, but they can also be grey, white, or black depending on your shirt's color and fabric. Yellow pit stains are caused by a chemical reaction between the aluminum in antiperspirant and the proteins from your sweat. When the two elements mix together and rub against the fabric, they create an unsightly yellow mark.

While there are plenty of detergents that can help remove armpit stains, sometimes you don’t have one handy – or you need something stronger. These armpit stain removal treatments are all made from products you probably already have at home – and most are chemical-free. You’ll find different variations of these across other sites; we found that these simple solutions require 1-2 ingredients (plus water) and all work.

Read on to learn about the best armpit stain removers and how to get rid of underarm stains on shirts using each one.

1. Baking Soda & Hydrogen Peroxide

What You Need:

  • Baking Soda
  • Hydrogen Peroxide
  • Water

Cleaning armpit stains with baking soda is one of the most popular ways on how to get sweat stains out of shirts. Combine the baking soda, hydrogen peroxide, and water in equal measures until fully mixed. (One-quarter cup of each is usually enough for one shirt.) Rub the paste into the armpit stains and allow it to sit for at least 30 minutes (longer for stubborn or previously washed stains). Use an old toothbrush to loosen the mixture off of the fabric, then wash the shirt as usual.

2. Dish Soap & Hydrogen Peroxide

What You Need:

  • Dish Soap
  • Hydrogen Peroxide
  • Soft bristle brush (like an old toothbrush)

For another option to get armpit stains out of shirts, combine the dish soap and hydrogen peroxide in equal measures until fully mixed. Spread the gel onto the stains and allow to sit for at least an hour. If the stains are stubborn, after one hour pour on some baking soda and use a soft bristle brush to scrub the stains, then wash the shirt as usual.

3. Aspirin

What You’ll Need:

  • Aspirin pills
  • Warm Water

Pit stains can be a real headache to remove, but you won’t even need an extra pill while using this pit stain remover. Crush up two aspirin and mix them with ½ cup of water for each shirt you want to treat. Apply the water to the stained area on your clothing and let soak for at least an hour. Then throw the shirt in the wash.

4. Oxygen-Based Bleach & Ammonia

What You’ll Need:

  • Oxygen-Based Bleach, like OxiClean
  • Household Ammonia
  • Rubber gloves
  • Soft bristle brush (like an old toothbrush)

In a well-ventilated room, put on the rubber gloves and mix equal parts of oxygen-based bleach and ammonia. (Two tablespoons of each is more than sufficient for treating one shirt.) Using a soft bristle brush, gently scrub the stains for 30-60 seconds. Then allow the mixture to sit on the shirts for 10 minutes before washing as usual.

This is the most heavy-duty treatment on the list, because it involves using two household chemicals to create a powerful stain remover. If you’ve had trouble getting rid of armpit stains using other methods, this is a good one to try. Do not use chlorine bleach instead of oxygen-based bleach for this mixture. Chlorine and ammonia mix to make a toxic gas! (Not safe for use on Ejis sweat proof products.)

5. Vinegar

What You’ll Need:

  • Vinegar
  • Water

Head to the pantry for this one! To treat one shirt, mix 2 tablespoons of vinegar with one cup of water; increase for each shirt you plan to treat. Apply the liquid to the stains, and allow to sit for at least 30 minutes. Wash shirt on a cold water setting. (Not safe for use on Ejis sweat proof products.)

6. Lemons

What You’ll Need:

  • Lemons
  • Water

If pit stains are one of life’s lemons, use real lemons to make a lemonade-like solution. Juice lemons to create a solution of equal parts of lemon and water. Apply the liquid to the stains, rub in the stains using your fingers, and allow to sit for at least 30 minutes. Then wash the shirt as usual.

7. Vodka

What You’ll Need:

  • Vodka
  • Water

Instead of drowning your sorrows, use vodka for pit stain removal. Skip your top-shelf vodka and opt for a lower quality one – it won’t impact the results. Mix equal parts of vodka and water, then soak the stains in the solution. After 20-30 minutes, wash the shirt as usual.

8. Salt

What You’ll Need:

  • Salt
  • Water

This is one of the easiest solutions for getting rid of pit stains on this whole list – so it’s a good one to try first. Mix four tablespoons of salt into 4 ¼ cups of water for each shirt you want to treat. Soak the stains in the salt solution for up to an hour, then wash as usual.

9. Meat Tenderizer

What You’ll Need:

  • Meat Tenderizer Powder
  • Water

It may seem unorthodox, but meat tenderizer can help remove pit stains. Wet the stained area using plain water, then sprinkle it with meat tenderizer. Let sit for a few minutes before washing as usual.
