Here is advice: * Are you sure the light is dirty on the inside? I detail headlights at used car dealerships and most of the time the outside is dirty it only looks like the dirt is on the inside. You can clean the outside with Crystalenz, this stuff works great. For more info check out the website www.crystalenz.com * You have to take the light off then take the bulbs out. Stick a rag inside the light through the bulb holes and work it around with a screwdriver to clean it. * Just dump some CLR in it. let it soak over night and rinse in the morning. Make sure you dry it (I used a hair dryer)

The answer to how to clean your headlight lens depends on how dirty your lens is. If it just has bug juice and road grime any good car soap will clean it, just be carefull not to scratch the plastic. However if your lens is really yellowed or the clear coat cracked then you will need kit designed to clean the lens.
