Cleaning oxidized aluminum?
I have a few items made from aluminum that I want to clean. One is a sauce pan from Allclad that accidentally found its way into the dishwasher. Not really important, but if there is an easy way, I will give it a try.
The more complicated task is a set of camera lenses. These are old Kodak cine lenses from the 40s, and a few of them are completely oxidized on the outside. I cannot really soak them in anything or attack them too harshly in order to protect the glas, and I also don't want any small particles getting into the focusing mechanism. It may be a lost cause, but maybe someone has an idea?
