I use Nolvasan/virosan and paper towels. I like the paper towels because they are disposable. Also, my wife gets nervous when I use the dish towels : )

Seriously, sponges, etc. are fantastic breeding grounds for micro-organisms (my wife is a microbiologist, which is why she's not into me using the dish towels). So using the same cleaning sponges, towels etc., without dissinfecting them thoroughly can result in smearing bacteria around your clean-looking enclosures; especially is you use the same sponge for multiple enclosures.

Happy cleaning!
