Hi friends:

Image

I'm restoring a Zenith console and am including a pic of some of the parts. The Zenith brass is dirty, as is the white plastic switches that get pushed and pulled to change tone quality and stations.

I don't want to get too brassy with say Brasso but would like to have all brass look sharp with some patina. Any professional suggestions to do it right using household items??

Also, the dial glass has lost its rubber buffer. They ALWAYS get hard and brittle and crack off. Any idea where I can buy another rubber for a 7-inch glass??

Look forward to your input. Ken

You can get the rubber extrusion (gasket/buffer) from RadioDaze.

Thanks Ed for the heads up on Radio Daze extrusion rubber.

Still hoping someone out there has some suggestions for cleaning up the brass.-Ken

Cleaning up that kind of stuff is always tough . Its probably lost its clear coating and now its all tarnished and spotted up . I found no way to clean that stuff up to look real good but still original . About the only way to get it real nice again is to polish it all up even and to shiney then apply something ?? to tarnish it back again to look vintage . I have had good results using toner over polished parts but it takes so darn long .

Start with some soap and water, and a magic eraser type pad for the scrubbing action. Gently, David

These are not brass, these are painted zinc diecastings! At least the switch modules and large bezel. I suggest a careful cleaning, maybe with a little automotive rubbing compound. Too much polishing will reveal more grey zinc.

Or consider repainting with an automotive metallic finish. There are small spray cans by Duplicolor that may be close.

Very interesting that they are actually painted zinc.

If thats the case, my first thought is to start with warm water and palmolive dish soap with a toothbrush. Get most of the grease and smoke residue off and see from there.

Ken, I restored a 10S567 where the finish was completely worn away at the bottom around the bandswitch wheel. The metal was grey. Certain edges do seem to be highlighted but I can't tell if that's a painting technique, shiny wear, or brass plating under toner. But they're not solid brass.....

I have to disagree on the bezel. My switch housings and steering wheel are brass plated zinc on an 8s563/8a02. But the bezel itself is actual brass from what I can tell. I think this is why they often appear to be a different color from the switch area. I cleaned my “bar keepers friend” and 0000 steel wool. Many people would argue that it’s too bright but i’ll Likely knock it back with some tinted lacquer.
