Tom,
I would also try Kerosene which is also a mild abrasive. Happy New Year. Carl Emerson Free Power Co.

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
