Cleaning outside of glass tank

Why risk it? A tiny amount of windex can crash your bio-filter and poison your entire stock of fish.

Good old H2O works fine.
 
You could also use plain ammonia (no soaps/surfactants.) Put it on a cloth and then wipe the glass.
 
if you use windex..spray it on the cloth away from the aquarium..
 
HI, Windex is fine but be VERY careful. Spray it well away from the tank. Try using water with a bit of vinegar mixed in. It works well. Not to much vinegar though or your room will smell like a french fry stand !!!
 
2 wet white paper towels, and 3 dry ones. Clean, and safe.

Use the wax on wax off method. :D
