Catsup cleans brass. Try some pool acid. I guarantee that it doesn't eat copper, but its 6m Hydrochloric acid so it will eat a lot of other things including your lungs if not ventelated.
Ah, memories of sulfuric acid and sodium hydroxide vapors.... I'm going to miss my chem class.
no, Sulfuric acid is expensive and hard to find. HCl is easy to get and doesn't react with copper(I don't thing Sulfuric does either). Its beautiful.
Hehehe...I know I miss mine. I was in A.P. Chem two years ago and that was the best class I ever took...for acid you want a very weak one...try...a one molar or less sulferic acid...and remember do as you otta and acid to wata.
