Sun damage, oxidation, and scratches can cause the clarity of car headlights and taillights to deteriorate over time and exposure to the environment. Headlamp function can be reduced by cloudy, foggy, or yellowed lenses at night or in poor visibility, which is especially harmful during the autumn or Winter season. Yellowing headlights reduce light output at night, impairing your vision and placing you and everyone else in your car at risk.

Fortunately, hazy headlights are relatively simple to repair. Furthermore, since headlight restoration is something you can do yourself, you won't have to spend much money at the mechanic.

We at Novsight care about you, and we believe headlight restoration is something you can do yourself, you won't have to spend much money at the mechanic.

Preparation for Headlight Restoration

Let's start the free restoration!


Sanding


Sanding is the most effective and time-saving method of permanently restoring car headlights. Sanding headlights remove the hazy coating and reveal the once-shiny light lenses you adored.


You'll need the following items:


  • Warm and soapy water

  • Clean water

  • Soft dry cloth

  • Tape for masking or painting

  • Plastic Polishing Compound Sheets - 600, 1,000, and 2,000 grit

  • UV resistant sealant on a flannel polishing cloth


Must Do's Before Sanding Your Headlights


  1. -Clean your headlights. Without appropriate cleaning, sanding headlights scrapes impurities deep into the surface, producing a rough, uneven surface with poor adhesion.


  1. -Clean the surface of the headlight lenses with warm, soapy water, then rinse and dry with a soft, dry towel. To aid with the next step, you may want to wash the surrounding surroundings as well.


  1. -Mark the area with tape. You don't want to sand off your car's paint by accident, as it would merely add another new and expensive vehicle problem to your to-do list.


  1. -Apply masking or painter's tape around the headlight area before you start sanding away to repair your headlights. Usually, two pieces of tape suffice. You can permanently remove your headlights if you still feel insecure after using tape, but this will be a lot of work.

Sanding Your Headlights

  • After cleaning your hazy headlights and taping off the areas, then you can now start sanding your headlights using some elbow grease and several grades of sandpaper. The finer the sandpaper, the greater the grit, so we recommend starting with the coarsest one and working your way up to the finest.

    1. Dry sand using 600 grit sandpaper, the coarsest one. It is recommended to sand your headlights in straight horizontal lines until the entire surface is covered and keep a consistent pattern until the foggy layer is gone.


    1. Sand your headlights with a 1000 grit sandpaper while wet. You can apply water as a lubricant to the surface of your headlights with a water spray bottle. And then, softly wet sand using a 1000 grain wet-dry sandpaper. Use constant sanding strokes while continuing to lubricate the surface with water.


    1. Then, use wet sand with 2000 grit sandpaper. Your headlights should appear clearer now, and this final sanding gives them an extra smooth effect. Using water as a lubricant, lightly sand the surface with a 2000 grit wet-dry sandpaper in regular motions.


    1. In addition, you can clean and polish your headlights. To remove sanding debris, wipe the surface with alcohol and paper towels, then use a flannel polishing cloth to rub in your polishing compound in regular motions. Then to finish the restoration, you can also apply a UV sealant to prolong the cleanliness of your headlights.

Quick Home Remedy To Clean Headlights

Baking Soda


Baking soda is a good cleaning agent since it is a moderate alkali that causes grime and grease to dissolve easily in water, allowing easy dirt removal. Baking soda is a safe and effective cleaner for glass, chrome, steel, enamel, and plastics.

  1. First, your old car headlights should be cleaned with soap and water.

  2. Combine baking soda and water in a mixing bowl.

  3. Make sure there's enough baking soda than water in the solution and come up with a paste-like consistency.

  4. Apply the baking soda solution to the headlight lens using a dry towel.

  5. Continue rubbing in a crosshatch pattern while applying the baking soda solution generously.

  6. To see the results, wash away the baking soda solution. Repeat until you reach the desired level of clarity.
