We have all been there done that.
Microfiber?! I thought I spoiled my snake. They have scales, they can handle the roughness that is a regular old washcloth!!!
I just toss a clean wash cloth in the tub whenever there is stuck shed and watch as poor old Dante flails helplessly in the dungeon of water I just made him go into. He still hisses anytime it is bath time so it never gets better!
