OK, I'm new to this forum but have lurked around here for a couple of years getting inspiration for my own project and it is almost finished. A problem I have is with smudges on my new aluminum skin. The aluminum seemed to have a thin film of manufacturing oil on it an I got sweaty while bending and fitting it and now I don't know how to get rid of the sweat smudges. I tried detergent but to no avail. Anybody got any ideas?
