Magic eraser is great on Prius headlights and paint marks

I haven't heard that before myself, but from what I've read and seen online about restoring cloudy plastic headlights is you sand off the top "dirty" layer to reveal fresh clear plastic below. Then the most important step is to apply some sort of UV coating otherwise they will get faded / foggy even faster without any protection from UV.

I got the 3M products on Amazon and they did a great job. Very cheap with a little elbow grease (and a drill) and they look great.

 

Magic Eraser is abrasive; I’d test it out on something less expensive before diving in on a headlight.

 

Not much different than the abrasives used in the headlight restoration kits. Just keep it away from the paint.

I was able to get rid of them with a lot of polish and elbow grease...

I also used car polish on my headlights (in a non- critical section) and it appeared to work. waiting to see what they look like after 6 months, but so far so good.

 

Mothers won't hurt the paint, that's what the guy in the video said. It didn't hurt mine either.
I didn't get a lot on it though, just the edges. You could tape it up if you wanted to be cautious.
It has been 5 months since I mine and they are just starting to show some fading. And they've been
in the sun a lot.
Next time I clean them I'll use the Meguiar's Headlight Coating on them and that's supposed to last a year.
I'm happy with the 6 months though, for 10-15 minutes of work...
