I worked with a guy that was an ex-Army Ranger, nice fellow, but I think he might have fallen on his head a time or 12 repelling upside down from a chopper.
Anyway, I came to the shop to do maintenance work on the trucks as he was cleaning them, and I noticed the floor in one of them was smoking!
He was using toilet bowl cleaner, which was 20% muriatic acid, straight from the bottle onto the aluminum floors of the box trucks.
Stunk to high heaven, but them floors were SHINY! 
A fairly strong acid was what we used to clean aluminum and stainless steel tanker trailers. .....and aluminum truck wheels and trim.
DO NOT USE ACID on aluminum that has a protective coating or you'll have to clean it every week after that.
BRILLO pads and acid made aluminum truck wheels shine like chrome.

But, under the name of ‘liberalism’, they will adopt every fragment of the socialist program, until one day America will be a socialist nation, without knowing how it happened.†- Norman Thomas, U.S. Socialist Party presidential candidate 1940, 1944 and 1948
