Hello Grace, I have very good luck cleaning tarnish off copper and
brass with the powdered cleaner found in grocery stores for use on
copper bottom cooking pans. The powder doesn't abrade the surface,
but I usually buff with a polishing cloth afterward. After you get
the pieces polished, clear coat them with a fine quality lacquer.
I've tried several products, but only one is non- yellowing, durable,
and non-detectible. I do mean, you can't tell it's there if you
apply it according to directions!! In fact, I just ordered a couple
12 oz. aerosol cans of the product I use. Here is the info: Product
is called 2105 Clear Lacquer, made by G.J. Nikolas & Co. Inc.
Distributor from whom I just ordered: McMaster Carr, Phone (620)
833-0300 Part #76885T62 The cost was just less than US$10 for
each can (plus shipping). A can lasts a long time. I usually
double coat items. It protects patinas as well as polished shine.
Is appropriate for any tarnishable solid or plated metal... copper,
brass, silver, etc. I'd avoid coating anything that is flexible, as
the lacquer might flake off when the metal is bent. Now, don't get
your knickers in a bunch, but I just clear coated my silver coffee
service and some sterling salt/pepper shakers. I'm tired of
polishing off the tarnish, but I want to display them. You CANNOT
tell they've been coated. BTW, I did not coat the interiors. Hope
this helps, Judy in Kansas where we finally broke the drought!
Wonderful sound to hear rain drops again.
