My polished red copper tees have a lot of finger prints on them and green sulphide. How will the finish be effected chucking them into citric acid?
Cheers

A quick pickle in Sulphuric/Nitric Acid (10%) with 1:10 Hydrogen Peroxide will yield perfect results.
Then use a copper clear coat that contains Benzotriazole. Wattyl Incralac
