"Cleaning and preparing aluminum and Copper alloys for oxidizing and clearcoating"



2005

I am trying to prepare brass and bronze pieces for oxidization and clearcoat, and aluminum for clearcoat only. I have seen metal etch solutions in hardware stores but they seem to be only for steel and aluminum.
What is a good solution to prep brass/bronze for a darkening and then its clearcoat?

For copper and brass You can use 10% sulphuric acid, on aluminum You can use very short dipping in 10 % sodium hydroxide solution.Other solutions are more complicated.
Before colouring You must degrease Your objects- Acetone [affil. link to info/product on Amazon] or alcohol are both usable(both very combustible).Good luck!
