As an example, acetone dissolve ink stains (liquid ink, gel, ballpoint pen paste). The effect is greater if the stain is recent. Note that the acetone can dissolve also the dyes of a textile material.
goof off works pretty good-but-a razor blade with soap and water works best
Mostly the changes are not chemical at all, but physical changes. It does depend on what kind of stain and what kind of detergent. Soap itself only works by physical changes, and not by chemical means at all. However, things like bleach or other bleaching agents (such as whiteners) do cause chemical reactions to remove stains.Perhaps somebody can add some information here about how bleach and whitening agents work?See the Related Questions to the left for more information about how soap works.
it is chemical because it changes the way your mind works chemically
Try soaking it in pure filtered reverse osmosis water. It will remove any gunk on it. If you dont have a reverse osmosis water filter, look for a place that sells water like water mart or similar place that uses reverse osmosis to purify their water. I use this water to remove stains out of carpets and to clean glass with no streaks. It works.

Alcohol based cleaners are often very effective to remove stains, depending on the type of clothing stained. Amonia (a household chemical) also works wonders.
Folex works great
Oil and grease stains are tough to remove from clothes because they resist water. The water in a washing machine works around the stain. Detergent makes it possible to remove oil and grease stains.
I heard that vinegar and a toothbrush works best.
Never Dull works well with some elbow grease.
A bleach is a chemical that can remove or lighten color, usually via oxidation. Rubbing alcohol can often be used to remove stains depending on their size. It works best with smaller stains. To remove a stain using rubbing alcohol apply the alcohol to a cotton ball and then rub the stain and the area around it. The rubbing alcohol will help distribute the original color of the clothing so that it begins to cover the stained area. This method is best used on darker colored items. Light colored items or items with larger stains tend not to absorb the color as well.
Use hairspray on it :) Sounds crazy but really works! ;D
Try deep woods off insect repellant. It will remove permanent marker off of most anything, remove fingernail polish and works on mosquitoes as well. It works. Ive tried it.
There is no single best way to remove all stains. The best way to remove a protein stain is with cold water and OxyClean. The best way to remove a dye stain is to use bleach if the fabric can handle it. Try looking up the best way to remove your specific stain.
Use Hydrogen Peroxide for blood stains. Works every time. Even on old blood stains in which case you just have to let it soak for a few minutes and you may have to repeat application a couple of times
