How to Remove Deodorant Stains from a Shirt Without Damaging the Fabric

You see yellow stains on the underarms of your shirts. These are deodorant stains, caused by aluminum in antiperspirant reacting with sweat and fabric. The stains build up over time and seem permanent, but they can be removed. Here’s how to remove deodorant stains from a shirt without damage.

A deodorant stain on a shirt is a yellow or white mark caused by aluminum compounds in antiperspirant reacting with sweat and bonding with fabric fibers. The reaction creates a waxy, yellow residue that builds up over time. Removing deodorant stains requires breaking down the waxy residue with a surfactant (dish soap), an acid (vinegar), or an enzyme cleaner (OxiClean).

To remove deodorant stains from a shirt, apply Dawn dish soap and let it sit for 30 minutes, or make a baking soda and vinegar paste and let it sit for 30 minutes, or spray with OxiClean and let it sit for 15 minutes. Wash with Tide Free and Gentle in warm water and check before drying. Don’t use hot water on protein stains, don’t use chlorine bleach on colors, and don’t put stained shirts in the dryer.

How to Prevent Deodorant Stains

Let Deodorant Dry Before Dressing

Wait 1 to 2 minutes for deodorant to dry before putting on your shirt.

Use Less Deodorant

A thin layer is enough. Using too much causes buildup.

Wear Undershirts

Wear an undershirt to catch sweat and deodorant before it reaches your outer shirt.

Wash Shirts Regularly

Don’t let deodorant residue build up. Wash shirts after each wear with Tide Free and Gentle.

Add Vinegar to Every Wash

Add half a cup of white vinegar to the rinse to prevent buildup.

Use Lysol for Odor Control

Add Lysol Laundry Sanitizer to the rinse for heavily soiled loads.

Clean the Machine Monthly

Use affresh Washing Machine Cleaner monthly.

What Not to Do

Don’t use hot water on protein stains. Hot water can set sweat stains. Use warm water.

Don’t use chlorine bleach on colored shirts. Use oxygen bleach.

Don’t put stained shirts in the dryer. Dryer heat sets deodorant stains permanently.

Don’t use fabric softener. It coats fibers and traps the stain.

Don’t rub the stain. Press gently or scrub with a soft toothbrush.

Don’t give up after one treatment. Set in deodorant stains may need 2 to 3 treatments.
