There have been many posts on the forums asking about which headlight cleaner to use to remove the yellowing oxidation of our headlights. Here's what I have found, I hope some of you find it useful.
After talking to the boys at Meguiar's about which product they have to clean the oxidation away, they were quick to recommend their PlastX – Clear Plastic Cleaner and Polish. Looking at the front of the 296ml bottle it claims to "remove fine scratches, cloudiness and stubborn oxidation".
Following the instruction I applied a small amount of the cleaner onto a Meguiar's applicator pad and started at the small side of the headlight to test the product. It started cleaning away the cloudiness well, moving over the rest of the headlight it was able to remove the yellowing well. You can see in the 3 way comparison, the cloudy before, during were I have only gone half way around the headlight and then the final result.
I used a Meguiar's Microwipe Polishing Cloth to buff the residue of the polish off. I needed to apply a little more of the cleaner, to get the residue that had dried off the plastic, to make it look perfectly clear. A final buff with the cloth to make sure no residue was left over.
Well the Meguiar's PlastX lives up to its claim of removing stubborn oxidation and clouding. I am pleased with the results, my only nit picking observation is that the liquid cause streaking that took application of more cleaner, cleaning and buffing to remove, however this did not take long so isn't a problem. Overall it took 5 minutes a headlight to get them looking clean and new. Ill keep you posted on how well the treatment lasts.
Best wishes
