I use paper towel, water and elbow grease to clean my reptiles enclosures. I have actually spent an entire day just scrubbing out 4 reptile pens but it saves using chemicals that I don't know are safe to use. Its also a good way to be extremely confident as to exactly what each reptile prefers to do.

I found spending the time scrubbing helps give me clues as to what my reptiles prefer. I picked up on enough clues partly from cleaning that I ended up managing to train two of my tortoises to respond to verbal commands - one will come running if I say pak choi and rip it out of the hand holding the pak choi.
