I was using a paint stripper to remove paint from 71 240z door strikers and the yellow nylon bumpers came out snow white. The same happened to the deep nylon adjusting nuts in the head light assembly.

This should make some of you restorer's happy.

Sorry no pics I was working more so than normal.

Here is a photo I found online. This restored set is in great shape but the nylon has a yellow streak on the top and a yellow tint on the bottom.

The paint stripper would remove all the yellow.

On throttle linkage... sort of yellow nylon to begin with so not a big change like the strikers.

Changed the metal a little too. Red flecks were from my paint brush and the work done earlier today.

Actually I have some that never oxidizes, they had a silver paint on them. They are white. You can't expect something that yellows all the way to be white again. Anyways a cool litle trick you found thanks for sharing.

You are removing the heavy, outer layer of oxidation and contaminants. Problem is, you don't know if it's going to lead to stress-cracking of the plastic later on. Not an issue with the door bumpers, but could be a problem on the throttle parts.

That said, most paint removers are a combination of caustics & solvents. Assuming these parts are thermoplastic nylon, it has good resistance to both of these chemicals, so it may OK.
