I use chlorohexadine personally. I order it from reptilebasics.com It is super super cheap to buy a big ole gallon. You mix a little with a bunch of water and it last FOREVER!!!! We clean everything with this ...snakes, lizards etc. I even clean off my counters with it when I am doing something with raw meat and when someone is sick in the house I use it to clean off areas. It will disenfect everything and is totally safe for the animals. In fact if your animals have any cut or scratches this is what vets use to clean wounds with.
I highly recommend it!!!! Plus the best part is ....it really has no smell to it which is nice when you have an enclosure without a lot of circulation.
What I do in our cages is spot clean everyday. So spray some on and wipe it up. Then once a week or so I will totally clean the cage. But typically this is easy to clean up any urine or poo right away. Plus I have a little brush and pan that I brush up the greens with each morning prior to putting new ones in. Seriously our cages are literally perfect all the time. It just makes life so much easier and for beardies especially its very healthy and clean. Plus no smell....I hate the way the sand smell. UGH. You can however put in a small box of sand for them to play in if you want. Bob has a small "toy box" in her enclosure and we can fill it with sand for fun.
