What You'll Learn
Use toothpaste
Toothpaste is a mild abrasive that can be used to remove scratches from plastic surfaces. It contains silica, which helps remove stains on our teeth. To determine whether toothpaste will work on a scratch, it is recommended to run your fingernail across the affected surface. If your fingernail catches, it is probably too deep to be treated with toothpaste. Whitening toothpaste is the best for the job as it often contains abrasive ingredients.
Before applying toothpaste, clean the plastic surface thoroughly so that any loose debris doesn't further scratch the plastic. Use warm water and a few drops of dish soap, or a small amount of rubbing alcohol applied on a clean cloth or cotton ball.
Once the surface is clean, squeeze out just enough toothpaste to cover the scratch and, working in small circles with a cotton round or clean, dry cotton cloth, buff until the surface begins to even out. Rinse the residue with water and examine your work. It may take a few applications and some elbow grease before you get the desired results.
If toothpaste doesn't work, you can try a different method. There are specialist plastic polishes available for this purpose, and you can also try using wet sandpaper so as not to introduce more abrasions.

Baking soda
To use baking soda to treat scratches, start by cleaning the plastic surface to remove any dirt or debris that could cause additional scratches during the process. You can use a damp cloth and rub in a circular motion around the scratch. Then, dry the area.
Next, create a paste by mixing equal parts of water and baking soda. Combine the mixture in a glass bowl for easy cleanup. Apply this paste to the scratched area using a cotton cloth or ball, working it into the scratch in gentle, circular motions. Allow the paste about 10 minutes to work on the scratch. Then, use a rag to wipe away the mixture. Rinse the area periodically with warm water and check your progress. You may need to repeat the process several times to completely remove the scratch.
If the scratch is deep, you may need to use a more aggressive method, such as wet micro-grit sandpaper, in addition to the baking soda paste. However, be cautious when using sandpaper as it can further damage the plastic if not used properly. Always start with the least abrasive method and work your way up to avoid causing more damage to the plastic surface.

Sandpaper
Use your fingernail or the edge of a credit card to help determine the depth of the scratches. If your fingernail or the card edge glides easily over the scratch without catching, then the scratch is shallow and can usually be removed with a gentle abrasive like toothpaste or baking soda. However, if your fingernail catches, the scratch is deep enough that you will need to use a more aggressive process with wet micro-grit sandpaper.
To remove scratches from plastic, you will need several grades of sandpaper, from 800 grit to 1500 or even 2000. Higher numbers indicate finer sandpaper. You can find sandpaper at any store that sells hardware supplies. You can often find it in assorted packs so you don’t have to buy a separate pack for each grade.
Begin with the lowest grit micro-grit sandpaper (360 grit). Soak the paper in a bowl of water for several minutes until the paper is saturated. Using steady, gentle pressure, rub the scratched area in a circular motion. After a few circles, rinse the plastic and assess your progress. If the scratch is still visible, move to a higher grit paper. Be sure the sandpaper is very wet and repeat the circular motion. Rinse the plastic after every pass of the sandpaper and continue to move to a higher number, finer grit sandpaper until the scratch has disappeared.
Finally, clean and polish the area so it looks like new. If you notice that the plastic has lost its lustre in the working area, apply a small amount of either plastic or metal polishing compound in a circular motion with a clean, dry cloth. You may need to repeat the process a few times, but eventually, the plastic will gleam as good as new again.

Polishing compound
Plastic is a versatile material that is used in a variety of applications, from furniture to car parts. However, it is susceptible to scratches and scuffs, which can affect the aesthetic appeal of the plastic item. While there are various methods to remove scratches from plastic, such as using toothpaste, baking soda, and sandpaper, sometimes the scratches are too deep or numerous to be removed completely. This is where polishing compounds come in.
When using a polishing compound, it is important to follow the instructions carefully. The compound should be applied in small amounts, using a clean, dry cloth, and worked into the affected area in circular motions. It may take several applications to achieve the desired results. It is also important to ensure that the plastic surface is thoroughly cleaned before applying the polishing compound, as any remaining dirt or grease can affect the outcome.
In addition to restoring the finish of solid plastics, polishing compounds can also be used for edge finishing of acrylic sheeting. This is particularly useful for creating a clean, finished edge on acrylic items, such as furniture or accessories. Polishing compounds can be found in different sizes, from small bars to large industrial sizes, making them accessible to both hobbyists and professionals.
Overall, polishing compounds are an effective way to hide scratches and scuffs on plastic items, restoring their original shine and aesthetic appeal. With their versatility and ease of use, polishing compounds are a great tool for anyone looking to maintain the appearance of their plastic belongings or acrylic creations.

Touch-up pen
If you have a scratch on a plastic surface, there are several methods you can use to remove or hide it. One option is to use a touch-up pen, which is particularly effective for deep scratches on painted plastic.
To use a touch-up pen, start by cleaning the plastic surface with a damp cloth and warm, soapy water. This will remove any dirt or grease that could interfere with the touch-up process. Dry the area with a clean, dry cloth.
Next, look up the correct paint code for your automobile. You can usually find this in the owner's manual or on a label inside the car. Once you have the paint code, find a matching touch-up pen at an auto supply store.
When you have the touch-up pen, simply draw it over the scratch, and the paint will be applied. Allow the area to dry before continuing.
After the touch-up paint has dried, apply a clear coat to the area. The clear coat will help blend the repaired area with the rest of the plastic, making the scratch less noticeable. You can find clear coats at auto supply stores and should follow the instructions provided with the product.
Finally, polish the area with car wax to restore shine and protect the surface. This process will help hide the scratch and improve the overall appearance of the plastic surface.
While touch-up pens are a great option for deep scratches on painted plastic, there are other methods to consider for different types of scratches and plastic surfaces. For example, light scratches on plastic can often be buffed out with a gentle abrasive like toothpaste or baking soda. Deeper scratches may require the use of sandpaper, starting with a lower grit and progressing to a higher grit as the scratch is buffed out. For any type of scratch, it's important to clean the surface and remove any dirt or grime before attempting to remove or hide the scratch.
