[TowerTalk] Clean copper

[Chris BONDE]

The tinners' solution has (I believe been also called 'killed' acid)  The old timers 
would take a certain amount of the acid plus a sealing ring from a preserving jay, 
the total zinc ones.  The reaction finished slightly acidic and was used to clean 
things.

No solvents, really, since what you are looking at is
corrosion/oxidation (copper oxide is black or red, depending on the
form).

Various forms of "bright dip" are available... usually consisting of
some mixture of nitric and hydrochloric acid.

Flux for soldering essentially produces the same effect, with a heat
activated chemical reaction (Ammonium Chloride (Sal Ammoniac) and Zinc
Chloride (Tinner's fluid) being notable examples).  The brush on
tinner's fluid is actually a mixture of hydrochloric acid and zinc
chloride, historically made by dissolving some zinc in HCl (but not
enough Zn to totally react with all the acid)..


If you don't want to fool with corrosive acids, one of the commercial
brass polishes might work (they use a combination of ammoniacal
compounds and a fine abrasive), but watch out for a film that they
often leave behind (to prevent tarnishing).
