K.W.
I had this happen once, and I remember also that nail polish remover DID NOT WORK. In fact, it just makes it worse. I looked around online and found somewhere that recommended WD-40. Believe it or not, with Wd-40, LOTS of scrubbing with one of those green scrubber pads, and a hot wash, I was able to get it out!
Good luck. It really takes a lot of elbow grease still!
