How to fix discolored coppers"

[60streeter]

Just looking for a good plan or product to give those very discolored coppers a uniform tone... preferably brown.... I have dug many with great detail, but horribly discolored.

I've been using white distilled vinegar, let them sit overnight and rinse.

I use peroxide, with good results, but you need to heat it up first, then watch it bubble crap way, lol Ask Tom how he cleans his, lol !!!!!!
