I have searched the entire site looking for suggestions on how to clean the clear "white" plastic section (reverse lights) of my taillight assembleys. With age, they have yellowed. I assume I will need to remove the taillight assembleys but I don't have a clue what to use to clean the yellowing from the inside?

Anyone have any experience here?

There is nothing you can do to remove the yellow colour but you can polish the plastic with cery high grit sand paper.(over 2000)

Thanks Peter,

I already polished the outside. The problem is inside and as you know that plastic is not smooth, there really is no way to polish all the nooks and crannies inside. I was hoping for a product I could spray on.

That's some old school hardware.

Its easily obtainable though;
Peroxide easily obtainable from hairdresser as it bleaches hair
OxyBoost from supermarket and a sun lamp

The plastic is oxidizing fron the outside, not the inside. Go to autozone and buy the 3m headlights restoration kit from autozone and use it on them (by hand). It will remove the yellowing, on the first grade of sandpaper, sand untilk the residue running off turns from yellow to white. What's happening to the taillights is the same thing that happens to modern headlights on most cars.

You can also use Meguiars PLast X to really clean up old dull wood clear coat. DONT USE ON DAMAGED WOOD however!
