I don't think it is an -actual- burn. Sounds like the skin came off and is pink underneath?

How exactly do you rip off shed accidentaly? When did she clear up from the blue phase? They shed 24-48 hours after so I am sure it wasn't really THAT premature :/

PAM is the way to go for mites, just follow the directions on the can. I think (don't quote me on this!) that you can spray the rack with the pam too.
