Pit stains can be embarrassing, especially when on a dark-colored shirt. It happens to everyone, but it is embarrassing nonetheless. Pit stains can happen at very inopportune times, before a big presentation, on a first date. While we can’t stop your level of perspiration, we can give you some tips on how to get your nice shirts back to being stain-free! If you’re using a laundromat or a campus laundry room you want every load to count!

Armpit Stains

It is no secret that pit stains are caused by perspiration. Each person perspires at different levels, some more than others. These people might be more affected by pit stains. Your entire body perspires but armpits are a hot, confined space of your body where sweat tends to pool and thus, you get pit stains. On a dark shirt, pit stains look like wet spots but people also get pit stains on white shirts or undershirts. These stains can look yellowish. The yellow coloration is actually caused by a reaction between sweat and deodorant. These stains can prove tough to conquer.

How to Remove Armpit Stains

There are a few possible DIY solutions to combatting pit stains, it is a matter of trial and error to find the trick that works for you! A good first step is to find a local community laundry room with powerful commercial laundry equipment.

Dish Soap

Dish soap flies under the radar as quite the useful tool when it comes to laundry. Dish soap works tough to clean dishes but also works hard on clothing too. For a yellowish pit stain that you can’t seem to get out, try mixing dish soap and hydrogen peroxide. Scrub the mixture directly into the stain and let it sit for about an hour before putting it in the wash.

Baking Soda

Baking soda, similar to dish soap, is another great substance when it comes to stain fighting capabilities. For armpit stains, you can either create a paste using baking soda and warm water, rub that gently into the stain and let it sit. For tougher stains, add hydrogen peroxide into the mixture and apply to the stain, again letting it sit for at least a half an hour.


Another way to get rid of those embarrassing pit stains is using vinegar. When dealing with stains, it is best to use white distilled vinegar. You can either pour vinegar directly onto the stain and rub it into the fabric before washing, or soak the shirt in a water and vinegar solution for about a half an hour before washing.
