How to Clean Dirt on Car Light Covers?

Remove the two rubber covers, take out the bulbs, and unscrew the two small lamp holders. Keep the two bulbs safe, being careful not to touch the glass parts to avoid damage, especially avoiding breakage. Mix a small bottle cap of dish soap, water, a cloth, and twenty to thirty grains of rice, then pour the mixture inside. Shake vigorously several dozen times to ensure thorough cleaning. Tap from the bottom upwards. If you can see a lot of dirt and debris hidden inside the light casing, shaking to a certain extent should suffice. Pour out the water mixed with dish soap and rice to clearly see how much dirt has been removed. Rinse the interior with plenty of water, repeating the process five or six times until the water runs clear. Wrap some cotton around the wires to dab out remaining dirt. Be extremely careful when wiping—the reflective material on the light bowl is more fragile than you might imagine, and even slight pressure can leave marks.
To clean headlight covers, I usually use a soft cloth dipped in soapy water to wipe them. For stubborn stains, I gently rub in circles with toothpaste instead of abrasive cleaners. Remember to avoid the sealant at the edges of the cover, as water seepage can cause fogging. If the cover is yellowed due to oxidation, use 3000-grit sandpaper with water to polish it, then apply UV protectant to slow down aging. During monthly maintenance, spray some hydrophobic coating—it significantly reduces dirt when washed by rain. Last time after a highway drive, the covers were covered in bug remains. I used a hot towel to steam them for five minutes before wiping, which protects the covers better than scraping. Plastic headlight covers are most vulnerable to alcohol and gasoline—corrosion-induced cracks are much more expensive to repair than cleaning.
