5 reasons why your headlights still look foggy after cleaning the outside lens

why headlights still look foggy
  1. Car Detailing with Toothpaste

If you choose to clean the outside lens of your car headlights with toothpaste, chances are they will still look foggy because toothpaste is not an abrasive manufactured for car headlights. 

  1. Simple Car Wax 

Most detailing shops when cleaning the outside of your headlight lens would only polish, run a buffer over the lenses, and coat with simple wax. This offers minimum protection and would get your headlights looking foggy again. 

  1. Car Cleaning with Only Automotive Soap

If you intend to restore your car headlight and you only clean the outside lens with automotive soap, then it would definitely look foggy once your car is dry. 

  1. Consistent Exposure to Sun Rays

Do you always park your car outside rather than the garage? If yes, it can be one of the reasons when your car still looks foggy. Constantly parking your car under the sun exposes your headlights to Sun Rays which causes it to oxidize and look foggy. 

  1. Wrong Restoration Kit 

During your car detailing, applying the right restoration kit is very important. Without a specialized restoration kit like clear light tech, your car can still look foggy after the headlight lenses must have been cleaned.


A more thorough method to go for would be procuring a restoration kit. With just one kit, you could combat oxidation of headlights and have that amazing result you wish for in your headlamp. There are several methods as we have seen, but a restoration kit is one of the best methods when it comes to headlight restoration.
