Just as in any cleaning task, in order to properly clean a headlight, you need to gather your materials. In order to properly do this task you will need to collect some rather specific items, or kits. Chances are that you won't have these items lying around the house you will need to make a run over to the local automotive parts store. Headlight cleaning kits will contain just about everything that you need, and a basic kit will cost you around $14.00. All headlight kits contain pretty much the same items. If you would rather make your own, then purchase one, here is what you will need.
- Several sheets of wet-sanding paper in 1000, 1500, 2000, and 2500 grit sheets
- Rubber or latex gloves
- Clean soft cloths (like microfiber cloths) or clean soft rags
- A bottle of plastic restoration polish
- Choose the day. It is usually preferable to do automotive cleaning, repairs, and restorations on a nice clear sunny day. That way you are outside in fresh air with plenty of space and ventilation, and enjoy the sunshine. If you cannot begin your project on a sunny day, or simply want to get it done as soon as possible, then as long as you have plenty of space, an area that can get wet with plenty of ventilation.
- Major imperfections. Begin by getting one of the headlights wet, after which you need to start sanding with the 1000 grit sand paper. Continue sanding until you have removed all the major imperfections on the lens. Only use the wet-sand type of sandpaper, as the other kind is not going to get you the results that you want. This step should take you about 30 minutes to do. However, it can take considerably longer depending on how foggy or dirty your headlights are. Conversely, it can take you almost no time at all. The key to know when to begin using the finer grit paper lies in noticing when the water and plastic runoff changes from a yellowish color to a more transparent and white color.
- Minor imperfections. After the major lens discoloration and imperfections have been removed with the 1000 grit wet-sandpaper, you are ready to move on. Repeat the process by using the 1500 and 2000 grit sheets. You will only need to spend about 15 on each sheet. An important thing to keep in mind when you are using sand paper is that when you change from the coarser to the finer, you should also be using less and less pressure, until finally you seem to be barely touching the paper to the headlight. Continue sanding with the 2500 grit paper as well, spending no more than 20 minutes on each headlight.
- Polish. Finally, polish the headlight till you bring it to a nice sheen. Simply apply the polish to the cloth you are going to use as an applicator and rub it in. Press down, using firm pressure and another clean, soft cloth or rag and begin polishing. While this process can take between 10 to 15 minutes for each headlight, you will love the results.
