Hi

I am in need of some advice for cleaning copper. I have used a vinegar
and
lemon juice solution but it seems to leave a slight discolouration on
the
copper and as well as smelling a bit rank it still requires some removal
of
the surface debris by hand. I have heard that hydrochloric acid is a
better
solution to use but I have no idea what percentage strength it would
have to
be or if there are any other better solutions available to buy and/or
mix.

Any advice would be appreciated

At the risk of stating either the obvious or the inappropriate: there
are a number of copper-cleaning compounds sold for kitchen pots and
pans. No safety issues, rinse off easily. Cost more than mixing your own
but are quick, risk-free and easy.

Don't know about you but I often find myself reinventing wheels, then
kicking myself for the lost time.

I can't help but agree, but the acid process can be more aggressive for
those cases where the chore at hand is extreme. For instance, you can
clean beryllium copper after heat treat and have it look great. That's
assuming you don't have a controlled atmosphere furnace at your disposal,
and I don't. After silver soldering, too.
