Guys i could really use some help with the best way to clean oxidation spots off some 5052 aluminum sheeting. It was covered to protect it from some recent rain but either condensation got between the sheets or the rain found its way through the plastic and it left some looks like hard water deposited and i could use some serious advice on a cleaner I have a little over 25 sheet hung:gloomy: didnít think it was any big thing but was wrong wont come off as easy as I thought it might.

so some professional input would be greatly appreciated.

Unfortunately thatís not an optional process for cosmetic aluminum sheets
