I'm restoring a very old product engine, the one with the red plastic backplate and no mounting. It's cleaning up well but the red plastic backplate is very dirty, it seems to have lain around for so long that the dirt has actually stained the plastic. Does anyone know how to clean it? I've tried most of the usual cleaners and it's a little better, but still looks very scruffy.

I am sure Mudhen can chime in here, as he has restored a lot of plastic backplates.

i'm familiar with the issue, my medallion has the same problem.
try srubbing it with an old toothbrush soaked in fuel, it helped my carb a little.

I've had some luck with BRASSO metal polish, it's a very fine abrasive. It’s sold as a metal polish, but works on most plastics as well.

The Brasso will work pretty well if it is mostly surface stuff.

I have had success removing a slight amount of material to achieve a new, clean surface. Usually the hard part is getting the right finish on the 'fresh' surface.

Solved it! I thought I'd try one last idea, before resorting to brutal methods! I left it soaking in a dilute solution of household bleach for a couple of hours, it's come up nearly like new! Even the stains have come out, amazing!

Estimate, about 5 - 10%

yep, its not fool proof, the idea is to take off the surface crud, you need to know when to stop.

Wilf,
Great discovery! I'll have try it sometime. Sound like the engines are comming around.

Mud,
Have you had any luck with the dreaded white residue left on plastic RTF's after clean-up?

Yes, I'm workin' on 'em!
Re: the white residue left, I polished my backplate with wax furniture polish, gets rid if most of it & helps restore the original plastic sheen, might work on RTFs too, and no harm done if it doesn't.
