So my wonderful girlfriend purchased me a large terrarium and a red eyed tree frog. After about 2 weeks of having the little amphibian, the glass has become dirty. I read somewhere online that I cannot clean the glass with Windex due to the risk of poisoning my new roommate. So what can I clean the glass with? I struggle with wipping down the sides of the class with just water because it makes it streaky and is ineffective. Suggestions? I also don't want to spend much for a new cleaner. Please help!
