Hello to the NG,
I have some old Eico gear & would like to clean up the copper chassis a
bit. There is black lettering on the chassis also. I'd like to clean up
the copper without taking the lettering off! Does anyone know what I could
use on the copper chassis without harming the lettering???

Thanks,
Steve K2FW



I would use a mild acid, like lemon juice, or tomato juice. They both make
copper shine right up. You must be sure to do a good rinse afterwards.

I cannot say for sure what would happen to the lettering, but as long as you
don't scrub, it should be ok.
