Re: Restoring discolored tail light lenses

I have used acetone successfully but you have to be very careful.
 
Use a clean soft cloth like from an old t-shirt.  Put acetone on cloth  and 
wipe the lens carefully, do not get carried away as the acetone will  dissolve 
the plastic and leave streaks.  A little bit at a time works  well.  I would 
practice on an old lens or the bottom or side first where  you can't see it if 
you go to far.  It will take the yellowing off.   After you take the yellow 
off, you can polish with clear coat compound and wax  if you like.
 
You buy a can of acetone at most hardware stores.
