After a few years of owning your car you may have noticed that the plastic headlight covers have become faded this can let down the appearance of your car, a simple car valet or a more extensive car detailing service will not be able to correct this.
Leaving the headlight cover not treated will just make the situation worse. This will seriously affect the operation of the light. This can be easily repaired without having to replace the light. Significantly increasing the appearance of your car. Especially if you are interested in a car detailing service.
Like the paintwork of a car, the headlight cover can be damaged by many factors, including acid rain, harmful UV rays, bonded contaminants, tree sap, bugs, and poor car washing techniques. Please see my Car Washing Guide.
How to Restore
First give the car a thorough wash. Whilst claying the car clay the headlight plastic surround. This will remove any bonded contaminants. A good quality plastic polish should then be used, this can either be applied by hand or with a machine polisher. The surrounding paintwork should be protected from the plastic polish to prevent damage.
If the headlight is to heavily faded you may need to use wet and dry sandpaper, making sure that the paper is kept wet. Use different grades until you have achieved the desired effect. It is best to use a machine polisher with the plastic polish afterwards to remove any marks caused by the sandpaper.
Once completed the headlight cover should now be crystal clear, improving the appearance of your car and the effectiveness of the headlight. The cover should now be protected with either a sealant or wax to prevent the headlight cover from fading again.
