Sunfading and patience....not a good thing for me....

depending on what the stain is.. it can take two to three weeks.. maybe longer..
you might wanna try getting some jellied peroxide from the local hair shop and applying some to a paper towel and then mummifying her.. or just her butt.. depending on where the stain is..
that might work a lil faster.

Jellied Peroxide? That is an interesting one, have you ever used it on brown spots, ink marks or pink spots before?
