Restoring yellow plastic
+
I'm restoring a British sports car. The plastic windshield washer
bottle has yellowed with age. Is there any way to restore the white
color of the original plastic short of painting? Maybe a dye or
chemical treatment?
Thank you in advance.

Try some 100% householed bleach. Caution on its use don't get it
on you or your clothing. It turn evething it come in contact with
white. Also clean the contaner out with water and let dry before
using the bleach.
Good luck

Sorry, Tim, but I think you are up a gum tree.
That 'white' and now yellowed plastic bottle is losing its fight
against U.V.
This is a typical behaviour pattern with Polyethylene. In time it
should stress crack and fail. That's why all commercial Pe pipe is
coloured black along with some other plastics, too.
May I suggest you just paint it. I don't think that bleach will do
anything for you.
Cheers !

As far as yellowed parts go, try this: denture whitener. A friend
of mine has refurbished many a weathered GI Joe Storm Shadow figures
using this technique.
