The instructions below will work on Mercedes Benz Models:

To restoring a Mercedes foggy headlights are the same as restoring the headlights on a BMW. The principle of restoring headlights remains the same throughout the industry. There are basically four (4) steps

1. Wet sand the foggy headlights from a coarse grit to extra fine grit
2. Polish you headlights
3. Clean the headlights with a pre-spray
4. Seal the headlights lenses with a quality headlight restoration sealant

Most Japanese cars you can start sanding with #400 grit sandpaper or possibly a 1000 grit and then move on to a 2000 grit sandpaper. But with German cars like Mercedes Benz we suggest start sanding with #220grit sandpaper especially if the headlights are partially foggy.

If your headlights are crystal clear on some areas and foggy or cloudy in the other areas that means you have some of the manufacturers sealant still on your headlights. Headlights in this condition are a little more difficult to clean and restore than those that are completely oxidized, yellow or cloudy white. Based on my experience in headlight restoration Mercedes headlights have extremely tuff sealant on them. Using #400grit sometimes skids off that sealant with very little effect. For that reason starting with #220 grit sandpaper would be more effective when restoring partially foggy headlights or headlights that are just starting to get foggy or cloudy on any Mercedes Benz vehicles.

What you need before getting started

1. EZ4U2 headlight restoration kit
   Kit Contents: 
   4 pieces wet / dry sandpaper- 1 each 220 /400 / 1000 / 2000 grit
    2 white and 1 blue towels, 1 glove, 1 polish, 1 pre-treater, 1 sealant and instructions.
2. Spay-bottle with water or water hose
3. Roll off blue, green or regular masking tape
4. A scissor
5. Paper towel or rags for drying and cleaning headlights and surrounding areas.
6. A shaded area to work comfortable

Specific directions for restoring Mercedes foggy headlights:

      i.        Tape around the headlight to protect your cars paint job

    ii.        Begin wet sanding your foggy headlights with the 220 grit sandpaper from side to side until your headlight has a consistent dull look.
Then go to the 400 grit followed by the 1000 grit and then 2000 grit sandpaper finishes your sanding. Now your headlights should look nice and clean with a low sheen

   iv.        Start polishing your headlights.
Apply a dime size amount of the fine cut polish on the white towel that came with your headlight restoration kit. Put a little extra energy in polishing your headlights. Obviously after polishing your headlights it would look a little brighter. Now they do not have to be crystal clear! That will happen when you seal them. Trust me you will be pleasantly surprised.

    v.        Pre-spray the headlight lenses with the lenses cleaner and leave it for about 10 to 15 seconds then wipe dry. The pre-spray strips away any grease or polish residue from the lenses. Plus it helps to open up the pause of the headlights creating the right condition to receive the sealant to make an excellent bond.

   vi.       Sealing your Mercedes headlights to look like new. 
This is where your hard work pays off. It's like magic! Right in front your eyes you will see your once foggy headlight transform to a like new headlight. 
You see from step ii to iv you were simply cleaning your headlights. By using a high quality headlight restoration sealant that is provided in the EZ4U2 headlight restoration kit makes all difference in your Mercedes headlight restoration.
Take the blue towel from the kit and saturate about one inch of it with the sealant. Next apply the sealant from one side to the next side of the headlight making sure you overlap by about 50% on each pass. Here is where you will understand why this headlight restoration kit is one of the best headlight restoration kits on the market today. Your Mercedes headlights will bring a smile to your face in amazement seeing them transformed from just clean headlights to headlights that look like new.

That’s how you restore the foggy headlights on a Mercedes Benz
