How Stain Removers Work?

The best stain remover that I know of, is bleach. It can only be used on whites though. I also use a color safe bleach but it does not remove stains like the bleach for, whites only, does.

well i have a vague memory from my high school days about my teacher explaining about how soaps and detergents work.. well i was too busy ogling some girls to pay any attention.. there was something said about detergents reducing surface tension of some sort.. guess it's the same with stain removers..

I have no idea how they work but I'm glad they do. My favorite is Shout for clothing and Resolve for carpets.
