Step by Step Guide to Clear Plastic Headlight Restoration

In this article, we take a look at a subject that affects nearly all car owners at some point in time – that of Clear Plastic Headlight Restoration. One of our regular customers recently pulled up outside our premises and asked me to take a look at his headlights which had become extremely clouded and dull over time from a combination of fine scratches and the effects of UV on the clear plastic.

Afraid that they were going to fail his upcoming MOT and not being able to afford a new set of headlights he wanted to know how he could restore the clarity back to his headlights.

I advised there are a number of different products available on the market which enable you to polish away light scratches, scuffs, haziness and surface marks from your headlights to leave them looking like new.

These range from single stage polishes, two step cleaning and polishing compounds to multi-step headlight restoration and protection kits.

Single Step Clear Plastic Headlight Restoration

Meguiars Plastic PolishProducts such as Meguiars PlastX are single step products that are best used on fine scratches and haziness. They tend to contain a blend of micro-abrasives and oils to restore the clarity together with water-resistant polymers for added protection.

Whilst simple to apply, needing only foam or microfibre applicator, they can however require a fair amount of “elbow grease” to get that like-new finish. As some of our own customers’ reviews testify:

Excellent Product  I had a Ford Focus Mark 1 with foggy headlights, which would have not passed the next MOT. After one application the headlights were clear and bright – made night time driving a lot clearer. I saved at least £200 over a replacement set of headlights. A second application made them look like new.   Kevin – Essex

However, being around £10 and under, they are very good value for the money.

Two Step Clear Plastic Headlight Restoration

Meguiars 2 Step Plastic Polish & CleanerIf you are looking at potentially the next level in your clear plastic headlight restoration a two step method may be the system to look at. This generally involves a separate clear plastic cleaner and clear plastic polish – another popular system, again from Meguiars, is the Mirror Glaze M10 (M-1008) and M17 (M-1017).

Meguiar’s Mirror Glaze Clear Plastic Cleaner is a non-abrasive, alcohol-free Plastic Cleaner that aggressively cleans and removes hairline scratches without harming the surface.  Whilst the Clear Plastic Polish provides the second step to protect the previously cleaned headlight and leaving behind an anti-static coating that helps repel damaging dust and dirt.

Headlight Restoration Kits

Your final choice in DIY headlight restoration is a multi step kit. These are very effective systems combining extremely fine abrasives and polishes to remove the scratches and dullness from your headlights and followed up a separate sealant and protectant.

Whether using a headlight restorer kit or supplies from your local auto store the following steps will help to restore that like-new clarity to your plastic headlights:

  1. First clean the headlights using your usual car wash shampoo to ensure all the dirt and bug splatter etc is removed
  2. Using a very fine 2000 grit wet and dry paper, work is over the surface of the headlight, keeping it moving so as not to concentrate in one area for any length of time
  3. Fill a spray bottle with clean water
  4. Fix a 2 inch (approx 5cm) backing plate to your electric drill (ensuring it is one that does not operate above 2000-2500 rpm)
  5. To the backing plate fit a
  6. Apply a suitable clear plastic polishing compound to the centre of the pad, place the face of the pad to the headlight and start the drill. Again ensure to keep the pad moving across the surface of the headlight. Do not keep the pad in contact with any one area of the headlight for more than 15-20 seconds
  7. As the polish drys out, stop the drill and using the clean water in your spray bottle, wet the pad and continue polishing until the haziness disappears
  8. Buff off any remaining polish with a clean microfibre cloth
  9. Next using a clean section or another clean microfibre apply one or more coats of a plastic protectant, allowing it to dry in between coats.
