Yup - soft scrub works great in my experience. Rinse well. Never had a problem. Although, never took a microscope to the glass surface after use...

The fine abrasive partials might be just the ticket. Kent Osterberg Blue Mountain Solar, Inc. Tom DeBates wrote: hello Wrenches, I recently purchased some used modules. Unfortunately, they were mounted near a railroad track and many have a film of rust on the front surface. I have tried a few products; Dawn, Simple Green, vinegar (5% acidity), and Krud Kutter to safely remove the rust. So far the vinegar seems to be best when considering cost, disposal ,etc. But it still takes a good amount of time and "elbow grease". Today I will try CLR. Has anyone else run into a similar situation? If so, what products and/or methods did you use to remove rust stains? Awhile back I had to remove some urethane caulk from the face of module and had to resort to a solvent-based chemical (acetone....yes, acetone) with disastrous results..... thanks, tom Tom DeBates Habi-Tek 524 Summit St. Geneva,IL. 60134 630-262-8193 fax 630-262-1343 ________________________________ _______________________________________________ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Options & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org
