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

The advice you've gotten is good, but let me add one bit of caution
about hydrochloric acid (muriatic acid).

If you store it indoors, even in a sealed plastic jug it will cause
severe rusting of all steel and iron in the vicinity.

I set my jugs of muriatic acid into a plastic bucket kept outdoors. To
keep out the rain and dirt, I cover all that with a larger bucket,
turned upside down.

Besides the storage issues, there are a whole bunch of safety
precautions you must use when handling any strong acid. If you're not
familiar with them, ask for help from someone that is.

Best regards,
