cleanining aluminum
I stopped using Simple Green 30 yrs. ago. It is very corrosive for all metals. The Air Force stopped using it about 15 yrs. ago for the same reason. They had to start replacing panels on aircraft because they were so thin from the affects of this product.
Has anyone had any luck cleaning the mottling off old aluminum parts? I have tried soda blasting, aluminum jelly and polishing compounds with little luck. Parts look cleaner but still have a mottled rather than bright shiny finish which they had when new. I'd like to get as close to that as possible. View attachment 81818
