Prior to the restoration process taking place, the headlight will be cleaned and any contaminants will be removed to ensure the best finish can be achieved on your headlights or brake lights. Contaminants will include residue from cleaning products over time, waxes and sealants and the general build up of dirt from bugs and dust to tree sap and water contaminants. This is only the start of the headlight restoration process and although the clarity may already start to improve at this point, it is unlikely a clean is all that is needed.

This requires a little more care, especially when being carried out with the light casing still fitted to the car. Be careful and use tape to protect the paintwork of the vehicle where possible, you will not want to get anywhere near the paint when sanding. The sanding process itself is not too aggressive and is simply to remove thin layers of the surface to cut it back to the clearer material below.
