The combination of sweat and deodorant can have an adverse affect on your clothing. Sweat contains a milder concentration of urea, also found in urine, which can lead to bleaching and discoloration of clothing. Together with the chemicals in deodorant and the paste-like residue they can leave behind white stains in the armpit area of clothing. When treating white armpit stains it is best to act fast to remove the protein stains before they become permanent.
Things You'll Need
- Table knife
- White vinegar
- Enzyme stain remover
- Laundry detergent
- All-fabric bleach
Lay the garment with the white armpit stain on a flat surface with the stain facing up. Remove any stain material off the surface of the fabric by gently scraping it with the dull side of a table knife. Repeat this until you have removed all deodorant residue or stain material collected on the surface.
Sponge a fresh armpit stain with a clean sponge dampened with undiluted ammonia. If the stain is old use white vinegar instead. Dab at the stain from the outer area into the middle to remove the bleaching and discoloration caused by perspiration.
Flush the site of the white armpit stain with warm water. Rub an enzymatic stain remover into the remaining stain. Work the stain remover into the fibers of the material by rubbing it in with your fingers then allow the fabric to sit for 10 minutes.
Launder your garment with laundry detergent and all-fabric bleach to remove the last traces of stain. Before placing the garment in the dryer check to make sure the stain was completely removed as the dryer's heat will set the stain. Repeat these steps a few times, as needed, for armpit stains that are difficult to remove.
