Video Tutorial on how to polish your headlights with toothpaste. This method does actually work, but it can be very work intensive compared to my other method of wet sanding. This works similar as to applying a polishing compound because toothpaste does contain an amount of grit/abrasive material. If you do have any stone chipping or heavier scratches in the headlight, toothpaste will not remove that as this method takes the contour of the light surface. Wet sanding on the other hand does remove more material and skins over the surface taking down any high spots. Your choice of wax can also be applied in the end to protect the lights over a longer period of time and give them a deep shine. Toothpastes that contain more of a grit/abrasive feel tend to work better than the types that don't. The outcome of the final product will depend on how much time you are willing to spend, what type of toothpaste you are using, and what the severity of the hazing on your headlights is. This will also work on other lights around the vehicle such as fog lights, parking lights, and tail lights. This process will last for almost a year until they need to be revisited again (when applying a protective layer of wax). This particular tutorial was done on a 1997 BMW 540i.
