How to Get Deodorant Stains out of Black Shirts

The combination of antiperspirant aluminum salts and heavy waxes with the body’s natural sweat, oil, and proteins makes deodorant stains.

This mixed chemical creates a sticky, water-resistant residue that attaches to the fibers of the clothes. On black shirts, stains become visible because the unabsorbed salts and powders dry into contrasting chalky-white marks.

Deodorant stains also worsen when you apply too much deodorant to your underarms and get dressed before it completely dries, allowing those wet ingredients to transfer directly to the wardrobe.

Living in rainy Seattle, Washington, I have been following several processes to remove deodorant stains from black shirts.

The Difference Between Colour Types (Black vs. White Shirts)

On a black shirt, deodorant stains appear as chalky marks because when you apply antiperspirant containing aluminum compounds and waxes, it mixes with the body’s natural sweat.

On a white shirt, deodorant can cause yellow stains because when you apply antiperspirant containing active aluminum to block underarm moisture, it reacts with the shirt’s fabric, leaving yellow marks.

Synthetics vs. Delicates

Synthetics

Cleaning Materials

• White vinegar
• Baking soda
• Dish soap

Synthetics are man-made fabrics that trap sticky marks, and when you are at home and see a stain in the underarm area, it is because these fibers stick to deodorant waxes.

Apply 50% white vinegar to soothe tough spots, then use a 75% baking soda paste on the mark, and clean sticky oils with 100% dish soap and 100% warm water.

Delicates

Cleaning Materials

• White vinegar
• Detergent
• Baby Shampoo

Delicates are fragile fabrics, like silk or wool, that are easily damaged. When you see stains on your armpit, it’s because natural fibers quickly absorb sweat and salts.

You can start with 50% white vinegar to soften deodorant marks, then use a mild detergent at 5% to melt away stains. Protect the fabric by cleaning with 100% cold water and 100% baby shampoo.
