Headlight Restoration via Crest toothpaste! Yesterday that head light was 50% covered with green tarnished film. I applied toothpaste after sun went down and rubbed it in this morning for 5 minutes. Total process took less than 8 minutes for both headlights. Locally companies wanted $65 to do what simple toothpaste could do. It’s not back to 100% factory new condition but I’m well pleased with results for half a tube of toothpaste.
