I used to use all those expensive terrarium cleaners, but now I use regular table salt. It takes off the slime and gives it a fresh smell. Just rinse thoroughly. I also have a spray bottle with a 10:1 water/bleach solution that I use twice a month for bacteria control. Seems to work very well on my Xenopus aquariums. I use a 5 gallon plastic container to hold the frogs during cleaning.
