Ok ,unfortunately my work areas for firearms and vehicles
are in the same space.

To keep it short ,
I got carbeurator cleaner droppings on a black plastic
stock for an HK-91.

I immidiatly wiped it off ,and rushed it to soap and water.

Now there is a white/grey residue on the surface.
Soap doesnt' work ,neither did Goo-Gone.

I tested in an unseen area ,ad I got some off with a stiif plastic brush.

If I get any rougher ,the pattern will come off.
Any ideas what I can use to clean it off ?

I really don't want to have to redye it.

The inside of it has had some mods I don't want to repeat on another.

Anyone ?

There maybe nothing you can do. Some "plastics" are damaged by the such strongsolevents as carb cleaners

But have you tried oiling the spot. It may be grey only because you've stripped off all of the old oils.

Plastic is damn near impossible to repair a stain on, IMO.

An even mixture of WD-40, blood and semen.

Can't hurt, can it?

Scotch Brite pad, compressed air, wax & grease remover, and a can of semi-gloss or flat black paint. Worked wonders after I FUBAR'd mine.

Well? Did anything work?

I put a thin coat of motor oil
(Castrol 10W-30 Synthetic blend)
on the stock and let it sit overnight.

The next day after returning home from work,
the gold like color of the oil was replaced by an
opaque gray/white where the spots were.

The original bright gray/white spots were darker ,
about a dark gray.

I decided to wipe it off and do it again.

After 3 days of doing this over again ,the spots have
nearly disappeared.

If you get up close you can pick out a slight pattern,but
from 6 inches away it's all the exact same color and
can not be picked out.

I absolutely could not believe how well this worked.

I let it sit without re-oiling it for a few days to see if it would
stay black and it did.

Thanks for the tip !
It saved me some cash ,and allowed me continue with my project.

Great news! I'm glad things worked out good for you.

I haven't used Duracoat, but I've gathered its a very good product and something to keep in mind for next time.
