foggy headlights

Recommended Posts

hi to all, does anyone know of a foolproof way of restoring foggy headlights,(outside) other than buying a kit from a motor store ?, so far , don't laugh!, I have tried baking soda and vinegar , and plenty of elbow grease, poor results, over to you, thanks.

As above...a kit would be the best...you could try some rubbing compound too.

Rubbing it with brake fluid will clean off the surface oxidation, then polish up with rubbing compound (or toothpaste if money is tight).

I tried Meguiars PlastRX on mine, less than a tenner for a bottle from Halfrauds - ideally it needs to be applied on a sponge attached to a drill, but as I dont have one, I rubbed it on and buffed it with a cloth. Takes a lot of rubbing and buffing, and just about removes enough of the fogging to get the car through the MOT, but the fogging usually comes back quite quickly, and every year, gets worse as the fogging proceeds to go from the top of the headlights, further down toward the bumper. Mk1 and early mk2 models are really bad for headlight plastics going foggy. The plastic surface seems to get permanently damaged by the sun. Yaris is not the only car to have this issue, it affects a lot of older cars with plastic lenses. Aftermarket headlight units are about £100 to £150 each, and if your car fails its MOT for excessive deterioration of the lenses adversely affecting the beam pattern, they will probably have to be replaced.
