How to Use Alcohol to Remove Stains on Clothes. Stains no longer spell the end of your favorite clothes. Most stains can be treated with a homemade stain remover-the very same rubbing alcohol that you probably keep around the house for cuts and scrapes. To remove stains with alcohol, follow these steps.
Place a paper towel, folded twice, inside the article of clothing and behind the stain.
Put some rubbing alcohol on a sponge and blot the stain.
Turn the fabric over so that the stain is face down, and put it on top of a fresh twice-folded paper towel. Make sure you can get to the stain and use the alcohol-soaked sponge to blot more. After you are done, replace the paper towel with a fresh one.
Add liquid laundry detergent to a fresh area of the sponge and gently rub the stain. You will probably need to replace the paper towel another time while doing this. Continue to rub the laundry detergent in with the sponge until most of the stain is gone.
Wash the garment with detergent in the hottest temperature the garment tag says it will allow. The stain should come out by the end of the cycle. Dry as usual.
