Can you get sweat stains out of hats, shirts, & mattresses?

Last Updated: January 4, 2022

To attack sweat stains and get them out completely, follow these steps using natural products.

Many of us have lost a shirt or two to unsightly sweat marks. Sweating in itself is a natural process, but none of us want to deal with the stains left behind (or the odor). Though it may be tempting, using bleach is not the answer, and products with chemicals may be making things worse.

Sweat stains are common in the underarms and other areas you sweat most. The stain happens when proteins in your sweat mix with chemicals in your antiperspirant. A shirt that hasn’t been washed properly can fester bacteria, and once you wear it again, the odor can come right back. While the bacteria in sweat stains isn’t harmful, it is the reason for the odor and will thrive in warm or moist environments.

Are sweat stains permanent?

Just because you have some stubborn sweat stains doesn't mean they’re permanent. With that said, not all stains are created equal, and some can be more difficult to get out than others.
