I just tryed this stuff they call Aluma Kleen from Sled-Brite.com, I can say it works great for cleaning off the oxidation/corrosion from alum, I did my trailer/shield and sled and it came out looking brand new. good stuff. I have to polish they recommend but I hav`nt tryed it yet...Sorry no pic`s(before/after)
