Headlight covers oxidise over time, causing a dull, foggy build-up. Aside from being unattractive, dirty covers dim the lights' brightness and make it less safe to drive at night. Clean your 2003 Honda CRV headlight covers with a mild abrasive for a crystal clear look. According to Repco Authorized Service, this method will remove any build-up without scratching the covers.
Mix a small amount of toothpaste with an equal amount of warm water in a bowl. Stir well with a spoon to make a thin paste.
Dip a sponge into the toothpaste mixture and apply it to the headlight covers. Rub the headlights in small, circular motions to remove any build-up.
Rinse the headlights with water and a clean, wet sponge. If there's any build-up still present on the headlights, clean them with more toothpaste mixture and rinse once again.
Dry the headlight covers thoroughly with a towel.
