Cleaning the outside glass

I pour rubbling alcohol on a paper towel, and ring it out, wipe the whole side of the tank down then with a dry towel to wipe off the alcohol. ... Spotless :)
 
I just use Windex or a simple streak free window cleaner. I then spray alittle on a dry washcloth and wipe the tank off. Once I see it is cleaned I turn the cloth over and use the dry side to dry any wet areas. Takes only a couple minutes to do the whole thing.
