How to Repair Yellowed Headlight Covers?
2 Answers
Methods to repair yellowed headlight covers: 1. Use professional cleaning agents and gently sand with fine-grit sandpaper to restore the covers to their original condition; 2. Apply insecticide to the yellowed areas of the headlights by spraying it on a cloth and slowly wiping until the covers return to their original state; 3. Use soapy water: it is a mild alkaline substance with gentle properties and high cleaning efficiency. Clean the headlights every three months, then polish them with a polishing agent and apply wax for protection. Avoid parking the car under direct sunlight for extended periods, as prolonged exposure can accelerate yellowing and aging of the headlights. Just like humans, cars also need sun protection. Do not use blades or sharp objects to scrape the headlights, as this can cause yellowing and leave marks.
Last time my car's headlight cover turned yellow, I tried using things readily available at home. First, I applied toothpaste on a cloth and scrubbed hard—the abrasives in it worked quite well, making the cover much whiter. Then, I applied a paste of baking soda for 20 minutes to neutralize surface acidity. Finally, I sprayed a layer of car wax as a protective coating. It took half an hour and cost nothing. I recommend doing this once a month, especially in areas with strong UV rays, as yellowing can affect brightness and make driving quite dangerous.
