Whether it's a car, plastic chair, dish, or accessory, scratches can be unsightly and decrease the value of your possessions. Luckily, there are a variety of scratch removal methods and products available, ranging from household items like toothpaste and baking soda to commercial scratch removers and repair kits.

Using toothpaste
Toothpaste can be used to remove minor scratches and scuff marks from plastic. It is a mild abrasive that can help buff out scratches without damaging the surface. It works best on superficial car scratches, also known as clear coat scratches, which do not go through the paint job and only affect the clear coat.
To use toothpaste to remove scratches, first prep the surface by washing the car with mild soap and drying it off. Use a microfiber cloth to dust any dirt or debris from the area around the scratch. This will help the toothpaste work better and prevent further damage.
Next, squeeze a pea-sized amount of toothpaste onto a soft, clean cloth. It is important to use a non-gel standard whitening toothpaste, as it has a rougher, grittier texture that will help buff out the scratches. Begin working in small circles on the scratched area, being gentle to avoid creating more scratches. As you move or lift the cloth, you should see the scratch begin to disappear.
Once the scratch is no longer visible, buff the area with a clean, dry cloth. Finally, wash and wax the area to protect it from future damage.
While toothpaste can be an effective way to remove minor scratches, it may not work for deeper scratches. In such cases, it may be necessary to use stronger abrasives like sandpaper or seek professional help.

Baking soda paste
Baking soda is a gentle mineral abrasive that can be used to buff away scratches on plastic. To make a baking soda paste, combine two parts baking soda to one part water. You can also add toothpaste, talcum powder, or isopropyl alcohol to the mixture. Using a cotton cloth, dip it into the paste and apply it to the scratched area. Work in a circular motion to buff away the scratch. Rinse the area often with water to check your progress. Repeat the process until the scratch has disappeared and the plastic surface is even.
If you are dealing with deeper scratches, you may need to use a buffer or sandpaper in addition to the baking soda paste. A buffer is a good option for harder plastics like acrylic and polycarbonate. You can turn on the buffer and hold the plastic up to the buffing surface to remove the scratch. For deeper scratches on softer plastics, you may need to use super-fine grit wet sandpaper. Start with a lower grit, such as 220-grit or 360-grit, and work your way up to a higher grit, such as 400-grit. Remember to always work in a circular motion and rinse the area periodically to check your progress.
After removing the scratches, you can apply a polishing compound or a buffing wheel to remove oxidation and make your plastic shine. You can also use car polish, such as Autoglym, applied sparingly on a very soft cloth and then buffed to a shine. It is important to proceed with caution when removing scratches from plastic, as using the wrong technique can dull the finish or create more scratches. Always test the method on a small, inconspicuous area first.
Additionally, it is important to keep the area clean and free of dirt and debris before, during, and after the process. Use a soft cloth or sponge to lightly scrub the plastic with warm water and a mild soap or dishwashing liquid. This will help prevent scratches and ensure a smooth finish. Overall, removing scratches from plastic requires some patience and elbow grease, but it is possible to restore your plastic items to their former glory!

Sandpaper
Firstly, you should assess the severity of the scratches. Run your fingernail or the edge of a credit card over the scratch and if it glides easily without catching, the scratch is shallow and can be removed with a gentle abrasive. If your nail catches, the scratch is deeper and will require a more aggressive process with wet micro-grit sandpaper.
Before you begin, it is important to remove any surface soil that might cause additional scratches. Clean the area with warm water and a few drops of dishwashing liquid, gently rubbing with a cotton round or microfiber cloth.
When using sandpaper, start with a lower grit number, as the higher the number, the finer the grit. Fold the sandpaper to fit the size of the scratch and wet it to avoid being too abrasive. Gently rub over the scratch in a circular motion, being careful not to apply too much pressure. Rinse periodically to check your progress and re-wet the sandpaper if needed.
If traces of the scratch remain, clean the area and move on to a higher grit sandpaper, repeating the circular buffing motion and cleaning after each pass. Continue to use progressively finer-grit sandpaper until the scratch has completely disappeared.
Finally, clean the surface again with a damp cloth. You may notice that the plastic has lost its lustre, so apply a small amount of plastic or metal polishing compound to bring back the shine.

Citrus oil cleaners
Before using a citrus oil cleaner, it is important to test it on a small, hidden area of the plastic item to ensure that it does not cause any damage or discolouration. If the paint is on a large surface, apply the citrus oil and cover with plastic wrap for about 10 minutes. For smaller items, place them in a container with the citrus oil cleaner for 1-3 hours. Then, use a plastic scraper or your fingernail to gently remove the paint. If the paint does not come off easily, you may need to use a stronger paint stripper or solvent.
One example of a citrus oil cleaner that can be used to remove paint scratches from plastic is Goo Gone. It is important to note that citrus oil cleaners may not be effective for removing well-dried oil-based or water-based paints. In these cases, a stronger paint stripper or solvent may be required.

Scratch repair kits
One popular scratch repair kit is the Meguiar's Scratch Eraser Kit, which has been praised for its effectiveness in removing light scratches from vehicles. The kit includes a scratch-removing compound that can be applied with a clean microfiber cloth in a circular motion with moderate pressure. The compound uses fine abrasives to smooth out the jagged edges of the scratch and blend the clear coat, filling in the scratch until it becomes invisible.
Another highly recommended kit is the Turtle Wax Premium Scratch Repair Kit, which has been found to completely erase light scratches. This kit follows a similar process to the Meguiar's kit but includes additional steps for more comprehensive scratch removal. One notable feature of the Turtle Wax kit is the use of a scratch repair pen, which can be extremely useful for deeper scratches that require more targeted treatment.
When using scratch repair kits, it is important to follow the instructions carefully and perform a patch test on a small, inconspicuous area first to ensure that the products do not cause any further damage to the surface. It is also recommended to polish and wax the repaired area to blend it in with the surrounding paint and provide additional protection.
In addition to scratch repair kits, there are also standalone scratch remover compounds available, such as the Formula 1 Scratch Out, which can be applied with a microfiber cloth in a simple one-step process. These compounds are designed to be effective and convenient, requiring minimal effort and time while still delivering noticeable results.
