The only time mine get a bath is when they have managed to roll around in their own crap. I have more than a couple white snakes and I don't like my white snakes chocolate covered. This "bath" consists of running the animals under a faucet and quickly rubbing the poop off. A 15 second process. I do not have bad sheds nor have to keep them "regular". I actually wish they were not so regular.

I think you may need to modify your thinking a little. If it is not broke, don't fix it.
