Hard Water Deposits

[Jester313]

I am getting a very nice aquarium from my uncle who is moving to NJ. The tank is pristine, except for some hard water deposits that are "staining and streaking" the outside of the aquarium.

What should I use to get them off of there?

try some vinegar, or i read lemon kool aid works so you can just use the unsweeten kind to make a paste. john

Any acid will work. Try Lime-Away from the hardware store.
