How to remove pit stains on cotton

The Solution

Armpit stains or "pit stains" are seriously the pits. Some more yellow and others more gray, stains from sweat or perspiration are caused by the combination of natural body oils, deodorant, and fabric absorption. While it's a common problem, it doesn't make it any less embarrassing! Don't sweat it. We've conquered the pit stain and so can you.

Apply product(s): Apply Stain Solution directly to the affected area. Then sprinkle our All-Purpose Bleach Alternative on the Stain Solution to create a powerful paste.

Work the stain: Work the solution into the fabric using your finger or our Stain Brush.

Pour water on the stain: For added cleaning power, pour boiling water from a kettle onto the affected area. (Pour from a safe height so the water won't splash on you). The force of the pouring water helps to do the work. You can also use water from a faucet set to its highest water pressure output.

Soak up to 30 minutes: Soak the item in a basin filled with hot water.

To remove odor: Stains and odor often go hand in hand. To remove odor, presoak the item for up to 30 minutes in a basin of hot water mixed with our All-Purpose Bleach Alternative.

Reapply or repeat as needed: If the stain is not completely gone, repeat this process until satisfied.

Launder the item: Wash according to our washing instructions.

Preventing pit stains: Ward off pit stains by pretreating items before every wash. Simply apply our Stain Solution or use our Wash & Stain Bar on pit-stain-prone areas before laundering.


Our recommendations: Our recommended stain and odor removal methods are solely based on use with The Laundress products. Our products are safe for colors, darks, and whites. We cannot guarantee the safety or success of products from other brands.

Using bleach: We don't recommend using chlorine bleach on stains or odors, ever. Not only does chlorine bleach deteriorate, degrade, and weaken fibers, it's not color-safe. In fact, it can cause whites to yellow and make certain stains even worse, such as rust stains. Instead, we use All-Purpose Bleach Alternative. Like all products by The Laundress, it's color-safe.

Drying: Do not put stained items in the dryer.

Ironing: Do not press stained items.
