This does work like a charm on stains on clothing. I even got out old stains that were on a Santana knit white St. John skirt. It was good as new.
Here's something you may not know about, tho...it works on rugs, too. Well, it would be hard to use on *big* stains on rugs, but I did get out a small coffee stain on our white carpeting in the bedroom. And we are talking dark coffee!
Check it out. It's a good idea to keep one in your purse. (No, they are not paying me to say this, but I am open for endorsements). :-D
