Mothers NuLens Headlight Renewal Kit

Cloudy headlights don’t just hurt a car’s appearance. They can also reduce nighttime visibility, which is a safety hazard. Mothers NuLens Headlight Renewal Kit bills itself as a restorer of yellowed or foggy headlights, so our product review team put it to the test.

This review will cover the effectiveness of Mothers NuLens headlight cleaner, discuss its ease of use, and give an informed take on the overall value of the product. Based on extensive testing, we rank the Mothers NuLens Headlight Renewal Kit as one of the five best headlight restoration kits on the market in 2022.

Mothers NuLens Headlight Renewal Kit Overview And Features

Bottom Line

Simple and effective kit that can be used in less than an hour

Pros

  • Large quantity of materials for repeat use
  • Can be used on headlights or taillights
  • Buffs heavily sun-damaged headlights back to clarity

Cons

  • Possible difficulties operating a drill if you don’t have much experience with one
  • Results not that different from hand-based washers
  • No UV sealer

For its headlight restoring product, Mothers NuLens requires wet sanding. The process involves using water to help lubricate sanding discs to help better clean the headlight lens.

What’s In The Box?

Besides instructions, Mothers NuLens Headlight Renewal Kit comes with only these four items:

  • Mothers NuLens’ PowerPlastic 4Lights® polish
  • PowerBall 4Lights® polishing tool
  • A drill attachment backing plate for the polishing tool and sanding discs
  • A bag containing sanding discs (800-, 1500-, and 300-grit)

Mothers NuLens assumes you will have a drill handy for the restoration process. If not, you’ll need to buy one. Other items you’ll need are materials for a car wash and microfiber towels for wiping the headlights off in between steps. Masking tape is also encouraged to help protect the area around the headlights.

Mothers NuLens Headlight Renewal Kit Testing Process

In testing the Mothers NuLens Headlight Renewal Kit, we primarily looked at three factors: results, clarity of instructions, and price.

  • Results: The main goals of a headlight lens restoration kit are to remove yellowing and improve clarity, but the longevity of the plastic polish is also a factor.
  • Clarity of instructions: Most kits don’t have a single-step application process, so readable and easy-to-follow instructions are crucial for this DIY project.
  • Price: Headlight restoration kits are fairly affordable in terms of automotive care, with most available for around $20. By comparison, the cost of replacing an entire headlight lens generally ranges from $60 to $200.

For our tests, we attempted to restore a severely sun-damaged headlight. Although the directions said it may take multiple passes to reach the desired clarity, we limited our test to one complete run-through.

Before putting sandpaper to plastic, we washed the headlight to make sure we weren’t sanding any dirt or grime into the existing plastic. After washing, we wet sanded the headlight with a variety of sandpaper grits until it met the manufacturer’s specifications. We then buffed the headlight and cleaned it with a microfiber towel until it reached a polished look.

What We Like About Mothers NuLens Headlight Renewal Kit

Besides the entire process taking only about 20 minutes to complete, there’s plenty our review team likes about the Mothers NuLens Headlight Renewal Kit. It comes with enough extra materials to service two or three other cars and have sandpaper and polish left over.

The restoration discs work very well, and it only took a few passes to remove built-up oxidation on our headlight. We also didn’t leave any unsightly hairline scratches, and the polish immediately cleaned the headlight.

What We Don’t Like About Mothers NuLens Headlight Renewal Kit

Even though Mothers NuLens supplies customers with plenty of materials for follow-up work, a renewal kit comes with only one 3,000-grit sanding disc. While this disc is the most heavy-duty of the bunch and is supposed to be used as more of a refining tool, having more than one would be ideal.

One issue with using a drill is that areas of the headlight such as corners and curves become hard to reach and properly sand. If you find uneven areas or smudges after a few passes, you can remedy this by using the sanding discs by hand. We should also mention that if you’re not accustomed to handling a drill, guiding a sanding pad may be difficult.

Positive Mothers NuLens Headlight Renewal Kit Reviews

Many customer reviews highlight how quick and easy the Mothers NuLens Headlight Renewal Kit is to use. They also tend to mention its affordability.

“Excellent! My headlights look as clear and shiny as new! Still have lots of polish left and will be using it for my motorbike.”

– Stefan via Amazon

“Each light took me about 20 minutes, and as you start to sand the lens down with the 800-grit paper, … it all comes together after the polishing sponge. I was impressed, and for $15 and some elbow grease (with a cordless drill), it was well worth it.”

– Elizabeth O. via Amazon

Negative Mothers NuLens Headlight Renewal Kit Reviews

Some more critical reviews say the oxidation remover didn’t work properly or the kit did a poor job of improving clarity. In other reviews, however, users admit that they didn’t correctly follow the instructions.

“I followed the instructions, and all it did was make matters worse. It sanded up a lot of the yellowing [material] into a pile on the headlight that I could not sand off. I tried all four sanding pads that came with the kit, and they all wore out and fell apart. . . . This was with one headlight.”

– Ted via Amazon

“I have now tried the polishing compound twice in this kit, and it does not work as advertised. . . . I have attempted to use [the kit] one time so far without success. The sanding pads don’t seem to work very well, and the polishing compound and pad/ball was not very effective at polishing out the sanding marks.”

– G. Nelson via Amazon

You might consider buying this product if you have cloudy headlights and want an easy DIY project you can knock out fairly quickly. However, if your car’s headlights are already clear or you’re not very comfortable using a drill, the Mothers NuLens Headlight Renewal Kit isn’t for you.

If you’d prefer to tackle this project without power tools, the Sylvania Headlight Restoration Kit or Chemical Guys Headlight Restorer might be a better option.
