Toothpaste for headlights?

[prr]

I just bought the Two Step Headlight Restoration Kit from Meguiars, because the headlamp covers on both of my cars have a lot of gunk on them.

After buying this, someone told me that they read/heard somewhere that you can clean off the plastic headlight cover, using toothpaste.

Has anyone done this before? What results did you get?

Tried editing original post 2x but still wouldn't take so here goes again.

Before Meguiar's and the like hit the consumer market with their products a generally accepted method was to make a paste from white (distilled) vinegar and cream of tartar to clean & renew Lexan headlight covers. It was just aggressive enough to remove the surface particulate matter and to reduce or remove the yellowing caused by UV exposure. Lexan's an incredibly tough cross-linked polymer that stands up well to particulate impact and discoloration caused by UV exposure.
