Polishing Brass, Copper and Bronze
This is just an overview of a much more in-depth approach to the subject, which you can read here.
Brass can suffer heavily through handling. Because it's not silver or gold, it tends to be very neglected. But what a beautiful metal! When it's properly polished and maintained it has such a bright glow. Museum polish makes brass give up a radiant beautiful lustre.
Again if you want to save on polish you can often remove bad oxidization with LEMON JUICE, or Vinegar, either of which will do the trick. Don't forget to rinse it off really well though, or dip the item in a solution of water and sodium Bicarbonate to neutralize the acid.
Copper, the perfect complement to brass, and beautiful in its own right. I don't understand people who get gleaming pieces of copper and have it artificially aged! I want to polish it every time I see it - that green oxidization drives me crazy. If it's really bad I nuke the oxidization with a mild acid solution, again vinegar does a fine job. Being a relatively soft metal, polish with Curator's Blend to achieve the ultimate lustre. Museum blend is also good on copper but is better suited to brass, bronze, stainless steel, nickel and
Bronze - the Boatman's metal, though being replaced more and more these days by stainless. Really severe oxidization I have been known to nuke with Muriatic acid. If you do this don't forget to have the sodium bicarbonate ready in order to prevent etching.
Then wash off really fast, and neutralise with sodium bicarbonate.
Normally exposed to the elements, nothing protects it against the salt air like laquer, I am sorry to say (only because I hate having to remove it for repolishes!). But the difference in lifespan between a
lacquered finish or waxed finish leaves only the one choice. A urethane
If the item is ornamental and not on a boat, our liquid polishes will give it all the protection it needs.
