It's pretty simple what the toothpaste does. it DOES not take down the edges of the scratch. What it does much like a rubbing compond is mar's the surface around the scratch to even the scratch to the surface that it is in. So in turn you are not removeing a scratch or in the head light case cleaning the "haze". What is actually happening is a layer of the material around the scratch or what not is being removed.

 

toothpaste might be the next duct tape if it can really do all this stuff
my headlights are gettting a little hazy so im gona clean them with toothpaste this weekend
i heard nail polish remover works and i tried it and it worked for about 2 to 3 mins

 

Just go to the auto parts store and buy plastic X. It's made by maguiers works great

 

I gave that a try and it worked considerably but they didnt impress me like I expected. Either way, Im lookin into some blackhouse headlights to replace them

DOT approved saves the pain in the @$$.

 

Did you repeat the application a few times?
