I hope you haven't tried anything yet, because whatever you try will only set the stain and prevent something that can really work.
My mom got red nail polish out of her white pants with Solumel. It takes out permanent marker, crayon, you name it! This product is from Melaleuca and it has over 100 uses. It is awesome! I even use it as ingredient in bug spray and my wonderful baby wipes.
Again, don't use anything if you haven't already, just wait if possible. I'd be happy to help you get this product into your hands. I rep the company that manufactures it (along with 300 + other products), I don't sell it, but I help others buy it at wholesale.
Please call or email and I can tell you about it.
