So when we purchased our tortoise, Rabbit, he had a spot of whiteout and permanent marker on the top of his shell. We tried a little bit of toothpaste to get it to come off and it dulled the Marker a little but didnt do much at all to the whiteout dot.. Any ideas on how to get this garbage off of our tortoises shell ?? Im tempted to use nail polich remover but dont want to harm him with chemicals...
