Nothing reduces visibility and aesthetics more than a set of headlights that have a foggy, yellow haze. However, you can make your headlights look like brand new by utilizing the right lens renewal system and some elbow grease.
Described in detail are the steps required to restore the clarity of your headlight lenses on your Mercedes-Benz. The steps are simple and the results – simply amazing. We renewed the lenses on a facelift w210 E55 AMG.
Things you will need:
1. 3M Lens Renewal System – Available at any auto parts store for around $25. This kit includes everything you will need minus a power drill. You must have a power drill to get good results.
Steps in completing lens renewal:
1) Clean the lights to make sure the lights are as clean as possible. It is also a good idea to clean the areas around the headlights. This will ensure that the protective tape adheres properly and doesn’t scratch the paintwork. After you have done that, lift up the hood and carefully cover the exposed body panels with the included green painters tape. Your results should look something like this (click the image to see how the lights looked before we started):
2) The next step involves a power drill. We used a drill that plugs in. If you drill is run off of a battery, make sure that it has sufficient charge to last for about 30 minutes of continuous use. Look in the kit and you will find a Velcro drill attachment. Lock this into place. Next, find the yellow sanding disk. There are six in the package. Apply the yellow sanding disk to the Velcro attachment. Sand the headlights by slightly tilting the drill and going in up and down motions. Do not leave the drill in the same spot, make sure you are continually moving the drill. This will eliminate the chance for any scoring. In this process you are trying to remove the oxidized yellow layer. Make sure to sand enough off the headlights so that the oxidized layer is removed. Change the sanding disks often to ensure proper effectiveness. Once you are done, it should look like:
3) After you have finished using the yellow sanding disk, you will switch to the white sanding disk (800 grit). Make sure to wipe off any residue on the headlights to ensure that the disk doesn’t get clogged. This process will smooth out the deep scratches caused by the yellow sanding disk. Make sure to follow the same precautions as before -replace the pads often and don’t hold the drill in the same spot. Sand until the headlights have the same uniform cloudiness.
4) Again, wipe off any residue from the lights to make sure you have a clean surface. Attach the grey sanding pad to the drill attachment (3000 grit). This process involves water to wet sand the lights to a smooth finish. Using a spray bottle, spray water on the headlight lenses and on the grey sanding pad. It is important to keep the headlights and the pad wet at all times. Wet sand the lights until they start clearing up. You will notice that the lights are starting to look almost clear and like new. Continue on all lights until the lenses have the same clarity.
5) Finally, attach the peach colored foam pad to the drill attachment. Included in the kit is plastic polish. Apply a little amount of the plastic polish on the pad. Make sure to smear polish you applied on the pad to the headlight, otherwise the polish will splash everywhere. Using a circular motion, polish the lights until they are crystal clear. You will need to add more polish as soon as the pad starts to dry up a little bit. After all of your hard work you will lights will look like they are brand new units.

As you can see, the kit is very easy to use and the results are superb. This is a project anyone can do to improve the visibility and restore the cosmetic condition of any Mercedes-Benz with plastic headlight lenses.
