Searching for a way to remove black paint from my grills, ran across this thread.

Seems oven cleaner is worth a try. I don't have a blast cabinet so walnut shells aren't an option.

Any other "plastic-safe" paint strippers available?

Brake fluid perhaps?

Ha! Good thought.... how many warning labels have I read?

[Greg Reid]

Yeah, but for me it has always worked much, much better when I accidentally spilled it on something that I did NOT want to remove the paint from..lol

FWIW I used walnut shells on delicate/plastic stuff in the past and it worked beautifully.

Case in point the taillight housings for my 70 GTO, took all the old crud, paint, etc. w/o harming the base plastic or whatever it is. Even the raised numbers cast in were unaffected, still sharp after being hit.

How fine are the walnut shell particles? Like sand?

I don’t recall the exact grit # we used, but it wasn’t a fine/sand like consistency. Medium-fine is my recollection. Wasn’t uniform either, that I do recall, 90/10 or 85/15 of measured particles to smaller/finer ones. I believe it’s gentleness comes from being soft/pliable. I was amazed at the stuff I hit with it, and the fact it didn’t butcher the base material.

It won’t remove rust or other “hard” material…carbon, paint, goo, dirt, etc. are what’s in its wheelhouse.

We had that, sand, glass beads and slag, depending on what needed zapping. That and a whole host of nozzles and jet things for the gun. I think we also had super fine steel shot, but I don’t remember using that.
