Hey, if your headlights are so bad you’re thinking of replacing them, you’ve got nothing to lose by trying this “3 minute headlight restoration” method. No need to buy polishing kits with successive grit pads and compounds.
I tried it on some nasty Subaru headlights and it really worked well. Then I coated them with a UV sealant.
The essentials:
Clean headlights well.
Scrub headlights with 0000 steel wool.
Clean again.
Wipe headlight in one swipe with acetone-soaked towel.
Let dry.
Treat with UV sealant.
