| Lime Away does help brighten metal to some extent. I've used bleach to neutralize it so that it cannot rust at metal seams and such. Going over the chassis with something like Brasso or Mother's Aluminum (metal) polish works well. The polish will take off printed numbers and letters, though. The guy on www.myvintagetv.com (great web page) says that he uses phosphoric acid to clean his chassis. He says that it will brighten the chassis without removing the numbers and letters. I've never tried it, so I don't know how well it works. His chassis look fairly good, though. They don't look polished, but they are brighter than as they began. Thomas |
