I just got an aluminum 10# CO2 tank, FULL,(re-dated 09/08) from Gearbeer for 45 bucks.
It is a little dirty and oxidized, so what do I have laying around my house to clean it with? I haven't cleaned aluminum for as long as I can remember.
Simplegreen, Barkeepers Friend, Brasso? I have no clue what to start with, so I figured that someone else has recently gone through all this before me.
What cleans aluminum up?
