Removing deep scratches from plastic sunglasses can be a straightforward process with the right tools and techniques. While minor scratches may be buffed out with household items like toothpaste or baking soda, deeper scratches often require more specialized methods. One effective approach involves using a plastic polish or scratch removal kit designed for polycarbonate materials, which are commonly used in sunglasses. Additionally, a fine-grit sandpaper or a polishing wheel can be employed to gently sand down the scratched area, followed by a thorough buffing to restore the smooth surface. It’s crucial to work carefully to avoid further damage, and in some cases, professional repair services may be necessary for severe scratches. Regular maintenance, such as storing sunglasses in a protective case, can also prevent future damage.

What You'll Learn
Using Plastic Polish
Plastic polish is an effective solution for minimizing deep scratches on plastic sunglasses, as it works by gently buffing the surface to reduce the appearance of imperfections. When choosing a plastic polish, opt for one specifically designed for eyewear or plastic surfaces to ensure compatibility and avoid damage. Brands like Novus Plastic Polish or Brillianize are popular choices for this purpose. These polishes typically come in multi-step kits, with different stages for cleaning, polishing, and finishing.
Before applying the plastic polish, clean the sunglasses thoroughly to remove any dirt, oils, or debris that could interfere with the polishing process. Use a mild soap and water solution, and dry the lenses with a microfiber cloth. Once the sunglasses are clean, apply a small amount of the plastic polish to a soft, lint-free cloth or a polishing pad. Work the polish onto the scratched area in a circular motion, applying gentle pressure. Focus on the scratched region, but also blend the polish into the surrounding area to avoid creating visible boundaries.
For deep scratches, multiple applications of the plastic polish may be necessary. After the first pass, wipe away any excess polish and inspect the results. If the scratch is still noticeable, reapply the polish and repeat the process. Be patient, as reducing deep scratches can take time and effort. Avoid over-polishing, as excessive friction can thin the plastic or cause other damage. Always follow the manufacturer’s instructions for the specific polish you’re using.
After polishing, use a clean microfiber cloth to buff the sunglasses to a shine. This step removes any remaining residue and enhances the clarity of the lenses. If the polish you’re using is a multi-step system, proceed with the finishing step, which often involves a finer polish or a protective coating. This not only improves the appearance but also adds a layer of protection to prevent future scratches.
While plastic polish can significantly reduce the visibility of deep scratches, it may not completely eliminate them, especially if the scratches are very severe. However, it remains one of the most accessible and effective methods for improving the look and functionality of scratched plastic sunglasses. Regular maintenance with plastic polish can also extend the life of your eyewear by keeping the lenses in better condition.

Applying Toothpaste Technique
The toothpaste technique is a popular and effective method for reducing the appearance of deep scratches on plastic sunglasses. This method works because toothpaste contains mild abrasives that can gently buff out scratches without damaging the plastic surface. It’s important to use plain, white toothpaste rather than gel-based or colored varieties, as these may contain additives that could harm the lenses. Before starting, ensure your sunglasses are clean by rinsing them with lukewarm water and drying them with a microfiber cloth to remove any dirt or debris that could cause further scratching during the process.
To begin applying the toothpaste technique, squeeze a small amount of toothpaste (about the size of a pea) onto a clean, soft-bristled toothbrush or a microfiber cloth. Gently dab the toothpaste onto the scratched area, ensuring it covers the entire scratch. The key here is to use a light touch—apply minimal pressure to avoid pushing the abrasives too hard into the plastic, which could worsen the scratch. Circular motions are recommended, as they help distribute the toothpaste evenly and work it into the scratch without creating new marks.
Once the toothpaste is applied, continue buffing the scratched area for 10 to 15 seconds. The mild abrasives in the toothpaste will gradually smooth out the scratch by removing a thin layer of the plastic surface. Be patient and maintain consistent, gentle pressure throughout the process. After buffing, rinse the area with lukewarm water to remove the toothpaste residue. Use a clean microfiber cloth to dry the lenses thoroughly, ensuring no moisture or toothpaste remains.
Inspect the scratched area to assess the results. While deep scratches may not disappear entirely, the toothpaste technique often significantly reduces their visibility. If the scratch is still noticeable, repeat the process, but avoid overdoing it, as excessive buffing can thin the plastic and weaken the lenses. Typically, two to three applications are sufficient to achieve the desired result.
Finally, to maintain the clarity of your sunglasses and prevent future scratches, store them in a protective case when not in use. Additionally, clean the lenses regularly with a microfiber cloth and mild soap to avoid buildup that could exacerbate scratches. The toothpaste technique is a simple, cost-effective solution for deep scratches on plastic sunglasses, but it’s always best to handle your eyewear with care to minimize the need for such repairs.

Wax and Heat Method
The Wax and Heat Method is a popular and effective technique for reducing the appearance of deep scratches on plastic sunglasses. This method works by filling in the scratches with a protective layer of wax, which is then smoothed out using heat. The process requires a few simple materials and careful execution to ensure the best results. Start by gathering the necessary supplies: a non-abrasive wax (such as carnauba wax or a specialized plastic polish), a hairdryer or heat gun, a clean microfiber cloth, and a soft-bristled brush. Ensure your sunglasses are clean and free of dust or debris before beginning.
Begin by applying a small amount of the wax to the scratched area of the sunglasses. Use the soft-bristled brush to gently work the wax into the scratches, ensuring it fills the grooves completely. Be careful not to apply too much wax, as excess can make the surface uneven. Once the scratches are filled, allow the wax to dry slightly, but not completely harden. This usually takes about 5–10 minutes, depending on the wax and environmental conditions. The goal is for the wax to be pliable but not sticky to the touch.
Next, use the hairdryer or heat gun to apply gentle heat to the wax-filled scratches. Hold the heat source about 6–8 inches away from the sunglasses and move it in a back-and-forth motion to avoid overheating any one spot. The heat will soften the wax and plastic, allowing the wax to meld into the surface more effectively. Be cautious not to overheat the sunglasses, as excessive heat can warp or damage the plastic. Heat the area for about 30–60 seconds, or until the wax appears smooth and level with the surrounding surface.
After heating, immediately use the microfiber cloth to gently buff the area. Apply light pressure in circular motions to smooth out the wax and blend it seamlessly with the rest of the lens. This step is crucial for achieving a clear, scratch-free finish. If any scratches are still visible, repeat the process by adding more wax, reapplying heat, and buffing until the desired result is achieved. Patience and precision are key to success with this method.
Finally, inspect the sunglasses under good lighting to ensure the scratches are no longer visible. If the lenses appear hazy or cloudy after the process, use a separate clean microfiber cloth to give them a final polish. The Wax and Heat Method is a cost-effective and accessible solution for deep scratches on plastic sunglasses, but it’s important to note that it may not completely remove the scratches—it primarily minimizes their appearance. Always test this method on a small, inconspicuous area first to ensure compatibility with your sunglasses.

Sandpaper and Buffing
Using Sandpaper and Buffing to Remove Deep Scratches from Plastic Sunglasses
When sanding, use gentle, circular motions over the scratched area, applying minimal pressure. The goal is to gradually level the surface without removing too much material. Work slowly and inspect the lens frequently to monitor progress. If the scratch is deep, you may need to repeat the process with progressively finer grits (e.g., 2000 grit followed by 2500 grit) to achieve a smoother finish. Always sand uniformly across the entire lens to avoid creating uneven spots or a noticeable haze.
After sanding, the lens will likely appear matte or cloudy due to the fine scratches left by the sandpaper. This is where buffing comes in. Use a soft buffing wheel or a microfiber cloth with a small amount of plastic polish or toothpaste (non-gel, non-abrasive). Apply the polish to the buffing tool and work it over the sanded area in circular motions. The buffing process helps restore the lens’s original glossy finish by smoothing out the fine scratches created during sanding.
For best results, use a handheld rotary tool with a buffing attachment if available, as it provides consistent pressure and speed. If using a manual method, ensure your motions are steady and even. Buff the entire lens surface to maintain uniformity, as focusing only on the scratched area can create a visible difference in texture. Wipe away excess polish with a clean, dry cloth, and inspect the lens under bright light to ensure the scratch has been removed.
Finally, clean the sunglasses thoroughly to remove any residue from the sanding and buffing process. Use a mild soap solution and a soft cloth to gently clean the lenses and frames. Avoid harsh chemicals or abrasive cleaners that could damage the plastic. With patience and attention to detail, the sandpaper and buffing method can effectively restore your plastic sunglasses, making deep scratches nearly invisible.

After the final layer has dried, gently buff the area with a soft cloth. This step helps to smooth out any excess polish and blend the repair into the surrounding surface. Be cautious not to rub too hard, as you don't want to remove the polish from the scratch. With this method, you can effectively minimize the appearance of deep scratches, giving your sunglasses a new lease of life.
This clear nail polish fix is a temporary solution but can be a great way to extend the life of your sunglasses without the need for professional repair or replacement.
