Sunglasses are a great way to protect your eyes from the sun's harmful UV rays, but they can easily get scratched and damaged. If your plastic sunglass lenses are scratched, there are several methods you can try to polish them and remove scratches. It's important to note that some of these methods may only work for shallow scratches, and deeper scratches may require professional help or lens replacement. One common method is to use a paste made from baking soda and water, which can be applied with a soft cloth or cotton ball and buffed away. You can also try using a small amount of metal or brass polish with a soft cloth, being careful not to get it on the frames. Other options include using toothpaste, glass etching cream, or vehicle cleaning wax. Always clean your lenses with a microfiber cloth before attempting any of these methods, and be cautious when using abrasive substances as they may damage your lenses further.

What You'll Learn
Use a non-abrasive paste, such as toothpaste or baking soda, and rub it on the lenses with a microfiber cloth
To polish plastic sunglass lenses, you can use non-abrasive pastes such as toothpaste or baking soda. Toothpaste should ideally be white and non-abrasive. You can also use baking soda, which is also non-abrasive and can be mixed with water to form a paste.
To begin, take a small amount of toothpaste and massage it between your hands. Then, apply the toothpaste to the lenses and gently rub it in a circular motion with a microfiber cloth. Rinse the lenses with cool water and wipe them dry with a non-abrasive cloth. Repeat this process if necessary.
Alternatively, mix equal parts of baking soda and water to create a paste. Apply this paste to the lenses and buff it with a microfiber cloth, again using small circular motions. Rinse the baking soda off and repeat the process if needed.
These methods are useful for removing minor scratches and restoring the appearance of your sunglasses. However, results may vary, and deeper scratches may require professional repair or alternative methods.

Try brass or silver polish with a soft rag
If you are looking to remove scratches from your plastic sunglasses lenses, one method is to use brass or silver polish with a soft rag. This method can be used if other methods, such as toothpaste or baking soda, have not worked. It is important to note that this method may not be suitable for all types of lenses, and it is recommended to verify that the brass polish is acetone-free before applying it to your lenses, as brass polish with acetone can damage the lenses.
To use this method, start by applying a small amount of brass or silver polish to a soft rag. Gently rub the polish onto the lenses in a circular motion, focusing on the scratched areas. Take care not to get any polish on the frames of your sunglasses, as it may damage them. Once you have applied the polish, use a clean, soft rag to wipe away any excess. Repeat this process until the scratches are no longer visible.
It is worth noting that this method may not completely remove deep scratches, and if the lenses are severely scratched, it may be best to consult a professional or consider replacing the lenses. Additionally, this method may remove any coatings on your lenses, such as an anti-reflective or anti-scratch coating, so it should be used with caution.
Another option is to use a glass etching cream, which can be effective in removing scratches from plastic lenses. However, this method can be costly and may damage the lenses if left on for too long. Always follow the instructions and take care when using any chemicals on your lenses.
By following these steps and taking the necessary precautions, you can use brass or silver polish with a soft rag to effectively remove scratches from your plastic sunglass lenses and improve their appearance and functionality.

Use car wax or vehicle cleaning wax
Car wax or vehicle cleaning wax can be used to polish plastic sunglass lenses. This method is only suitable for plastic lenses, as it will ruin glass lenses. It is also a method of last resort for plastic lenses, as it will remove all coatings from the lenses, leaving them more vulnerable to scratches.
To polish your plastic sunglass lenses using car wax, start by cleaning the surface of the lenses to determine the location of the scratches. Use a cleaner made specifically for glasses and a clean microfiber cloth. You can obtain this from any optician's office or eyeglass store.
Once you have cleaned the lenses, apply car wax to the scratched area. Use a microfiber cloth to rub the wax into the lenses in a circular motion. Continue rubbing until the scratch is repaired. You may need to scrub the lenses with water and a microfiber cloth to remove any remaining wax.
Other products that can be used to fill in scratches include scratch-filling wax, Armorall, and a mixture of alcohol and baking soda.

Glass etching cream is effective but can be costly
Glass Etching Cream: An Effective but Costly Solution for Polishing Plastic Sunglass Lenses
If you have scratches on your plastic sunglass lenses, you may be considering various methods to polish them and restore their clarity. While there are several DIY approaches, such as using toothpaste, baking soda, or vehicle cleaning wax, these methods may not always deliver the desired results, especially for deeper scratches. This is where glass etching cream comes into the picture as a highly effective solution.
Glass etching cream, which is readily available, contains hydrofluoric acid, a powerful ingredient that helps remove the plastic coating on the lenses. To use this product, apply a thick coating of the cream to the surfaces of the lenses. It is important to let the cream sit for around 5 minutes without rubbing it in. After this, rinse the cream off with cold water and wipe the lenses dry with a clean cotton cloth or towel.
While glass etching cream is highly effective for removing scratches from plastic lenses, it is important to remember that it is a temporary solution. It may not work in all cases, especially if the scratches are very deep or stubborn. Additionally, it can be more costly compared to other DIY methods. If not handled with care, it can also cause damage to the lenses if left on for longer than the recommended time.
When using glass etching cream, always follow the instructions on the packaging. It is also important to note that this method is only suitable for plastic lenses and should never be used on glass lenses. If you are unsure about the type of lenses you have or if the scratches are too severe, it is advisable to seek professional advice to avoid causing further damage.

Use metal polish with alcohol
Plastic sunglass lenses can be polished to reduce the appearance of minor scratches. Before attempting to polish your sunglasses, it is important to give them a thorough cleaning. Use a mild soap or eyeglass cleaning solution and a soft cloth to remove dirt and grime.
To polish plastic sunglass lenses using metal polish with alcohol, follow these steps:
- Add a small amount of metal polish, such as Brasso, to the lens. Be careful not to use too much.
- Get a clean cloth or tissue and use it to buff away the scratches on the lens. Be meticulous when buffing and repeat multiple times, especially if the scratches are deep. This step may take a while, so don't lose patience.
- Apply some alcohol to a cotton ball and thoroughly clean the lenses. Be sure not to inhale the fumes.
- If needed, apply a scratch filling product. If scratches remain visible on the surface of the lenses, apply a product that will fill the scratches temporarily with wax. Rub the product onto the lenses using a clean microfiber cloth in a circular motion, then wipe it off with a clean area of the cloth.
It is important to note that this method may not be suitable for all types of lenses, and it is always a good idea to consult the manufacturer's recommendations before attempting any repairs. Additionally, avoid using harsh chemicals, acetone, ammonia-based cleaners, or rough materials like paper towels that can damage sunglass lenses and coatings.
