List- I am looking for information on cleaning aluminum. The surface in question is approximately 25 years old and looks as if it was originally polished. I have removed some areas of whitish oxidation with gentle scrubbing and a mild detergent, however, the surface below seems to be pitted. Although what appears to be pitting may also just be residual oxidation that I have not been able to remove. I have not been very aggressive in cleaning thus far. Also there are areas where the surface has become discolored to sort of a bronze tint. Has anyone has any experience, luck, success with returning an aluminum surface be returned to its original appearance, and if so, how? Thanks, Mark
