In the course of a day, getting stains on your clothing is a commonplace occurrence no matter how careful you are. To remove a stain from clothing, treat the stain as soon as possible so it doesn't set. Use bleach to treat stains on fabrics that allow use of bleach. Generally, you can't use bleach on wool, silk or spandex. After you treat a stain, put the clothing into the laundry and wash it.
Look at the tag on the article of clothing you intend to treat. The tag should provide information about how to wash the clothing. If it warns against using bleach, don't use bleach to treat a stain. You could damage the fabric.
Test the bleach on an inconspicuous corner of colored clothing to check its effect on the color. Use approximately a tablespoon of bleach in 1/4 cup of lukewarm water. Blot dry after one minute.
Mix 1/4 cup of bleach in a gallon of lukewarm water. Completely immerse the clothing into the mixture. If you're treating cotton fabrics, soak for no more than 15 minutes, according to the University of Iowa Extension. If the stain is still there after 15 minutes, bleach won't remove it and you risk damaging the fabric if you continue to soak it.
Rinse thoroughly with normal water and wash the clothing in a laundry load.
Using Paper Towels
Test a small corner of the clothing with diluted bleach solution to determine its effect. Never use pure bleach; follow the instructions on the container.
Place the article of clothing facedown on top of a paper towel or white cloth.
Pour diluted bleach onto the underside of the fabric. According to the Butlers Guild website, this pushes the stain off the fabric rather than through it. This is more likely to completely remove the stain.
