Scratches on plastic items are inevitable, whether it's a plastic windshield, car interior, or household item. While some scratches may be overlooked, they can build up over time and become unsightly. Luckily, there are several ways to hide or remove scratches from plastic, and you likely have the necessary tools and supplies lying around your house. This includes using household items like toothpaste, baking soda, and sandpaper, or commercial products like plastic polishing compounds. The chosen method will depend on the depth of the scratch, with deeper scratches requiring more effort and possibly specialized products.
| Characteristics | Values |
|---|---|
| Scratch removal methods | Toothpaste, baking soda, sandpaper, polishing compound, touch-up pen, clear coat, car wax |
| Scratch assessment | Use fingernail or credit card to determine depth; shallow scratches can be repaired with light abrasives |
| Surface preparation | Clean with warm water, dish soap, and a soft sponge or microfiber cloth; remove dirt, grease, and grime |
| Toothpaste application | Squeeze non-gel toothpaste to cover scratch; buff in small circles with a dry cotton cloth; rinse with warm water |
| Baking soda application | Mix equal parts water and baking soda to form a paste; apply with a cotton ball or cloth in circular motions; rinse |
| Sandpaper technique | Start with coarse/micro-grit sandpaper, then progress to finer grits; soak sandpaper in water; use gentle, circular motions without applying too much pressure |
| Polishing compound | Apply a small amount of plastic or metal polishing compound in circular motions with a clean, dry cloth; repeat as needed |
| Touch-up pen | Look up paint code for automobile and find matching touch-up pen; draw over the scratch |
| Clear coat | Apply clear coat to blend the repaired area with the surrounding plastic; follow product instructions |

What You'll Learn
Toothpaste
Before applying toothpaste, clean the surface to remove any debris that could cause additional scratches. Next, squeeze out enough toothpaste to cover the scratched area. Using a dry cotton cloth, work the toothpaste into the scratch in small circles, applying light pressure. Rinse the area frequently with warm water and check your progress. You may need to repeat this process several times until the scratch disappears. Once the scratch is removed, clean and dry the area with a damp cloth to remove any residue.
If toothpaste alone does not remove the scratch, you can try creating a paste with equal parts toothpaste and baking soda. Apply this paste to the scratch and work it in with gentle, circular motions. Rinse periodically to check your progress and repeat as needed.
For deeper scratches that cannot be removed with toothpaste, you may need to use a different method such as wet sandpaper or a plastic polishing compound. It is important to proceed with caution when attempting to remove scratches from plastic, as using the wrong technique can dull the finish or create more scratches.

Baking soda
Before you begin, it is important to assess the severity of the scratch. Run your fingernail or the edge of a credit card over the scratch; if it glides easily without catching, then the scratch is shallow and can be treated with baking soda. If your nail catches, then the scratch is deeper and may require a more aggressive process with wet micro-grit sandpaper.
To treat light scratches with baking soda, start by cleaning the plastic surface to remove any dirt or debris. Use a damp cloth and rub in a circular motion around the scratch. Dry the area thoroughly.
Next, create a baking soda paste by mixing two parts baking soda to one part water. You can adjust the quantities as needed to form a thick paste. Apply the paste to a clean cloth or cotton ball, and gently work it into the scratch using gentle, circular motions. Rinse the area periodically with warm water to check your progress. Repeat the process until the scratch is no longer visible.
Finally, clean and dry the treated area with a fresh cloth. If desired, you can apply a small amount of plastic or metal polishing compound in circular motions to bring back the shine to the plastic.
While baking soda is effective for light to moderately deep scratches, very deep scratches may not be removable and may require a replacement. Additionally, always test any cleaning process on a hidden area of the plastic item to ensure it does not cause further damage.

Sandpaper
If the scratch is shallow, it can usually be removed with a gentle abrasive. If your fingernail glides easily over the scratch without catching, it is shallow and can be removed with toothpaste or baking soda.
For deeper scratches, sandpaper can be used. It is recommended to get several grades of sandpaper, from 800 grit to 1500 or even 2000. The higher the number, the finer the grit.
Before buffing, clean the plastic surface thoroughly so any loose debris doesn't further scratch the plastic. Then, wet the sandpaper to avoid it being too abrasive and gently rub over the scratch in a circular motion. The abraded area should be larger than the scratched area. 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.

Polishing compound
Before applying the polishing compound, it is important to clean the plastic surface thoroughly to ensure that any loose debris does not cause further scratches. Use warm water and a few drops of dish soap, or a small amount of rubbing alcohol applied on a clean cloth or cotton round.
After cleaning, you can apply a small amount of either plastic or metal polishing compound. Make sure to apply it in circular motions with a clean, dry cloth. You may need to repeat the process a few times until the scratch is no longer visible and the plastic surface is restored to its original shine.
It is important to note that the depth of the scratch should be considered when deciding on a repair method. For deeper scratches, it is recommended to use fine-grade sandpaper before applying the polishing compound.
Additionally, it is always recommended to test any repair method on a small, hidden area of the plastic item first to ensure that it does not cause further damage or discolouration.

Touch-up pen
If you have a scratch on a plastic surface, such as a plastic countertop or your car, there are several ways to fix it. If the scratch is on painted plastic, a touch-up pen can easily hide the problem.
First, clean the plastic. Take a clean, damp cloth and dip it into some warm, soapy water. Gently rub it in a circular motion all around the scratch. This will remove any dirt and grease, making it easier to get rid of the scratch. Dry the area with a clean, dry cloth. You can use a microfiber towel.
Next, use a touch-up pen. Look up the correct paint code for your automobile (check the owner's manual or look for a label on the car). Find the matching touch-up pen at an auto supply store. Most of the time, all you have to do is draw the pen over the scratch, and the paint will be applied. Let the area dry before continuing.
After applying the touch-up paint, you can apply a clear top coat to the area. This will help blend the buffed area back in with the rest of the plastic. You can find clear coat at auto supply stores. Follow the instructions provided with the product. If it’s just a small scratch, you can probably just paint the clear coat on the area. Work in a well-ventilated area.
Finally, polish the area with car wax. Once you’re done and everything’s dry, get some regular car wax.

Frequently asked questions
You can use a touch-up pen to hide scratches on painted plastic. For car scratches, make sure to use a pen that's approved for automobile use. Alternatively, you can use a plastic polishing compound or toothpaste to buff out the scratch.
The best method depends on the depth of the scratch. Start by cleaning the surface with a damp cloth and mild soap. For light scratches, use a gentle abrasive like toothpaste or baking soda. For deeper scratches, use fine-grade wet sandpaper.
Regular cleaning will help to prevent scratches from accumulating and becoming deeper. It will also help to prevent a cloudy white film on the plastic from becoming permanent.
