Hey guys I would like some of your help for my most recent problem of oxidation on most of the aluminum parts. I have tried steel wool but it barley removes the oxidation. I also tried one of those drill attached 3M Power Sanding Paint And Rust Stripper () it works very well but leaves behind scratch marks that I also cant get rid of. I am asking you guys if you know maybe of some readily available chemical remover or another 3m remover device that wont scratch. Thank you.
