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)

Inside or outside? Outside is pretty direct. A damp cloth usually does the trick. If the inside is dirty, I'd buy a CD lens cleaner and use it. That will solve any crud on the lens problems. If the inner workings have become dirty due to blowing dust or something, You may have to yank it out and have an auto audio shop clean it up for you. FriPilot
