Cleaning a Copper Chassis
 

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.

Cut small piesces of tape and cover the writing .
Be very careful of what you use, cleaning the copper is hard because
it's plating and could be removed easily.

Brasso works well, also, but requires some buffing.

Hmmmmm. Mayhaps you are correct?? The can doesn't say abrasive.. but it
doesn't say it isn't either. I've been using Brasso on brass for a
mellinium and it did/does work on things like Drake LP filters and other
brass items. It will, of course, take the silk-screen markings off. I
should have mentioned that... for sure.

Brasso IS abrasive. Many, many hours spent polishing collar brass on
Army uniform.
