I've been using Windex for 10 years, no issues

50/50 Vinegar/RO. wipe/scrub with one cloth, then buff with another

50/50 Vinegar and a squeegee

ya brad i've been using windex up until recently, i noticed that when the front panel gets bad water stains the windex kind of smears it, vinegar and water doesn't leave any noticable streaks as i can tell

drock169 i noticed you said you use newspaper, i've heard of this several times, i'd imagine the ink wouldn't release as people wrap there live rock/stock in it for shipping all the time without ill effect-

Is using news paper an uncommon thing for cleaning glass? I've been using news paper since I was a wee little lad .....

First time I heard of the newspaper thing

I've used newspapers for most glass cleaning like mirrors, car windshield, windows, and exterior of the fish tank. It works great for not leaving streaks. I aim the windex away from the tank and spray a bit of it on the newspaper before wiping it on the fish tank.

Compare and Contrast
 

Globe, National Post, Sun, National Enquirer?

The National Enquirer wpn't work. All the B.S. in it smears the glass.:mrgreen:

Another newspaper user here. Water with a little vinegar and newspaper.
