How to Get Rid of Armpit Stains

Let’s face it: we have all dealt with one of the most difficult laundry challenges: removing armpit stains from a shirt’s underarms. 

But there is a way to defeat these ugly yellow or dark armpit stains—and the best armpit stain remover, such as Vanish, is the surprising answer to this persistent problem.

Read on to learn how to get rid of armpit stains and save your favorite shirt from unnecessary disposal. 

What causes armpit stains? 

Sweat is a mixture of water, proteins, salt, fats, and the skin’s natural bacteria. When these components interact with fabric, they can leave behind a residue commonly recognized as sweat stains.

The best time to combat a sweat stain is when it’s fresh. Using the best stain remover for armpit stains, such as Vanish, helps break down the mixture for easier stain removal.

First and foremost, armpit stains, or any sweat stain, must be treated as soon as possible. Over time, untreated sweat stains can permanently discolor clothes, making them difficult, if not impossible, to remove. 

To remove armpit stains from white clothes, use Vanish Oxi Action Crystal White Powder; for colored clothes, use Vanish Oxi Action Powder. 

There are three methods for utilizing Vanish products to eliminate stains: Pre-treat, Soaking, and adding directly to the Wash. 

Although pre-treatment and soaking are typically reserved for tough stains, the in-wash method is the simplest and can be combined with pre-treat or soaking.
