I use Virosan buy it from Pro Exotics
You can use it on everything including your hands or right on the snake
Kills all germs and no need to rinse and no smell.
Won't harm your snake they use it when they have small cuts etc or for oral sugery
Great stuff, bleach scares me as you have to rinse rinse and more rinse.

I do rinse water bowls etc out good after using.
The stuff works well and is not expensive I think like 8.00 for a lagre spray bottle
