Acid wash - what is this??

[PSU1981]

Considering going to a truck wash my 2015 27FB FC. They offer an acid wash. What is this? Do I want this or not & why?

Thanks,

Glenn

Never acid wash on AS. Destroys finish on aluminum.

Correct if its something polished it will take the shine off in a hurry. Its used on aluminum fuel tanks that are not polished. It will make dull aluminum brighter but not to the luster of polished. No easy way good old fashioned elbow grease and a buffing wheel.
