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
