← Stain and Surface GuideSweat and Deodorant Stain Removal Guide
Sweat stains and the yellowing that comes with them are usually a reaction between deodorant aluminum and body oils, so plain detergent often is not enough on its own.

Clothing (White or Light Cotton)
- Make a paste of baking soda and a small amount of water, and work it into the stained area with an old toothbrush.
- Let the paste sit for 30 minutes, then rinse it out under warm water.
- Apply a liquid laundry stain remover directly to the spot and let it sit for another 15 minutes.
- Wash in the warmest water the care label allows, then check the spot in sunlight before drying, since the sun can help fade any remaining yellowing.
Safety note: Avoid chlorine bleach on deodorant stains, since it can react with the aluminum compounds and turn the yellowing a darker, harder-to-remove color.
Clothing (Colored Fabric)
- Mix equal parts white vinegar and water in a spray bottle and lightly saturate the stained area.
- Let it sit for 15 to 20 minutes, giving the vinegar time to break down the residue without affecting the fabric dye.
- Rub a small amount of liquid stain remover into the spot, focusing on the underarm seam.
- Wash on a normal cycle in the warmest water safe for the color, then check the spot before drying.
Safety note: Spot test the vinegar solution on a hidden seam first to make sure it does not affect the fabric color.
