As a result, whether washing foggy headlights with vinegar as well as other household solvents is necessary, it is essential. There is cloudiness above the headlights when the polycarbonate oxidizes.Ĭloudy or foggy headlights are a typical problem that every car headlight has, so here is what you need to know about them: they may make a vehicle’s headlight appear pretty unpleasant, and they can even cause accidents since they obscure or hinder the view of the road. Coating protect the plastic, but the film dissolves over time as a result of naturally accumulating dust and exposure to UV radiation. Car headlights are polycarbonate plastic, which is naturally porous despite being very stable. Popular Mechanics even did a comparison test of a bunch of kits and ranked them for you here.The reason for your headlight’s fogginess is simple but also a bit scientific. It is basically a clear paint that seals the plastic from reacting with the oxygen in the air or UV rays from the sun.Įven with the cost of the needed supplies and the labour involved, restoring headlights is much less expensive than buying new headlight housings on most cars. Some of these wipe on, and some spray on, but all of them work about the same. The last step, and most important for long lasting crystal clear headlights, is to apply a clear UV and oxygen resistant coating. When you are done with this step you should have an almost new looking headlight, but it would stay that way long without the last step. Rub it on, polish the scratches left from the sandpaper, and wipe it clean with a damp rag. Some people have suggested toothpaste can be used, but it doesn't work as well as a dedicated polishing compound or plastic polish.

Typically you start with 1000 grit wet/dry paper, and a small bucket of water to dip it in. You actually may get away with skipping this step and moving right onto the polishing compound if they aren’t too bad. How coarse a grade of sandpaper you start with depends on how bad your lenses are. The abrasives used to fix headlights can ruin paint, so you want to mask around the headlight as well before you move to the next step.
Wax the car as well, including the headlights this may actually vastly improve the fogginess. This way you get a much more accurate idea of exactly what you are dealing with.
Like a lot of car appearance and maintenance tasks, it helps to start by washing the car. Obviously to fix a foggy lens from the inside you will have to remove the housing and access it from the rear. Fixing them, despite promises to the contrary from many products, involves labour and abrasives. Inside there is less that can affect them, but the UV from the bulb itself is enough, as well as moisture from bad gaskets around the bulb socket. The outside is prone to damage from road debris, sandblasting from bugs and dirt, and general degradation from UV light and oxidation.
