The best thing that I can suggest is to let him soak for a few minutes and then let him crawl around through a wet towel...
I tried letting him go through a wet warm towel but he didn't like it so i sprayed down his substrate and put some damp cocofiber in his warm hide. I don't want to mess with him.
