Need shop to clean old electroformed copper waveguides

2004

I have some electroformed copper parts and some copper alloy and BeCu copper rectangular tubing that is corroded due to exposure over years to condensation of water vapor. The corrosion is a light green (patina) color. These parts are used for RF waveguide purposes, and quite valuable, so I am interested in finding someone who can try to clean and remove the copper oxide (e.g., dilute sulfuric acid, Chem Brite, etc. treatments).

I may be able to find some pictures if someone is interested to see some examples.
