white vinegar works like a DREAM.

so does ammonia free glass cleaner and a fresh razor blade.  I get wierd looks from guests when they see the razor blade and glass cleaner on my desk next to my cages, but hey, my glass sure is clean...

+1 to vinegar I use 220 grit black sandpaper 

My dart frog tank had deposits on it from where it was used before my frogs got put in. Best thing I could have ever done with it? I took a whole lemon, cut it in half, and rubbed it all over the glass with quite a bit of elbow grease. Then I took a paper towel to whipe it off gently and boom, all gone!!

+1 on the lemon.  I use just regular old lemon juice from a bottle though... just pour some on a paper towel and start wiping (I rinse w/ water after, just to be safe).  I use it to clean all of my glass tanks.  It's also great for those pesky geckos that like to "go" all down the glass.  The lemon juice takes it right off!

I'll have to try those. Would that 220 grit sandpaper scratch the plastic of the dishes - I know that would probably make future cleanings more difficult.

It's the baked on stuff that is in the plastic and ceramic water dishes that really gives me the difficulty.

I have used the vinegar for hard water problems on cages and dishes, and definitely rinse thouroughly! Never heard of lemon trick, but that sounds very interesting!

P.S. As far as standard cleaning of the glass on cages/tanks/terrariums, I use listerine in a spray bottle, it cleans & disinfects and does not have the strong after smell of bleach, but a nice pleasant smell ;)

FYI, If you use RO (reverse osmosis) water, you'll never have to worry about hard water deposits again.

try rep-zilla terrarium spray its safe, and you can use it on any cage surface.
