Thread: Rehydrating hard rubber

Any way to turn this stuff back black from this brown color it has?

Polish it.

I think once the brown is removed and the fresh black is exposed and polished it makes for and easy recovery. I did try soaking some in silicone lube once but I don’t think it had any impact on the overall project. I was afraid to try mineral oil because of that whole oil and rubber issue and I did not want to have them become rubbery.

If it's actually neoprene (a plastic), then try isopropol alcohol. If it's real rubber,
try this: TECHSPRAY 1612-2SQ RUBBER REJUVENATOR.

It works on copy machine/printer rollers, but you may be talking about rubber scales.
I dunno about them. Never tried it. But it does work on copiers and printers.

There used to be a product called Fedron, which worked very well, but that
was 25 years ago. I don't think it's available anymore.

Need to try that stuff on the rubber rollers on thickness planer. I’ve tried using paint thinner moistened rag but like rez said, not sure they’ll play nice.

Just polish the scales, real light sanding with 1k or 1.5k should do it then polish. They turn brown from oxidation, a decent furniture wax afterwards should help slow the process.

Another thing you could try is to rub them down with glycerine.

I typically sand them with 0000 steel wool, then polish.
with Flitz. Repeat, until desired results.

Pinned or unpinned, don't matter.
