well something you could consider is giving him a warm bath and hope he'll submerg and then let him shed it on his own. Since that won't alway's work sometimes if it's olny a small patch I'll leave it be and next shed it'll be gone. i don't know if it'll work if it dosen't it probably happens in the wild and I don't think it'll make a huge deal?
I dunno just try and give it abath and see wht happens good luck!
