My big tank is beloved by the kids and the cats. It's fairly new (got it for Christmas) so it's just now getting to the point where the nose and appendage prints from both cats and kids are needing to be swabbed away. Seeing howas my sorority and more live in that tank, I'm wondering if there is anything that it's best to clean it with. I'm thinking I shouldn't be spraying Windex around near the tank, but can I put that on the cloth say, in a different room and use it on the exterior? Or should I just go with H2O only?
