Always read and follow the care instructions and any warnings on the garment label. And, follow the General Rules for washable fabric stain removal.
Perspiration, if allowed to stay in fabric, will eventually stain and weaken the fabric. Aluminum chlorides in antiperspirants will also weaken the fabric under the arms. Controlled use of antiperspirants and frequent washings immediately after wear can minimize this type of damage. Wearing an undershirt or perspiration pads, can also keep stains off your shirts or blouses. Also, consider experimenting with different anti-perspirants/deodorants.
These types of stains can be difficult to remove. And, the build-up of aluminum chloride or zinc salts may be impossible to remove. Old stains are more difficult to treat because they have been set, particularly from being heated in the dryer.
- Rub light stains with a liquid detergent and then launder.
- Pretreat heavy stains with a prewash stain remover. Allow to stand 5 to 10 minutes.
- Launder using an all-fabric bleach.
- If fabric has discolored, you might try treating fresh stains with ammonia and old stains with WHITE vinegar.
