What You'll Learn
Clean the plastic surface
To smooth out scratches on a plastic surface, it is important to first clean the surface. This will help provide an ideal environment for any mixture in the next steps to be more effective. Here are the steps you can follow to clean the plastic surface:
Firstly, make sure you have the right materials. You will need a clean cloth, some warm water, and a mild detergent or soap. It is also recommended to have a microfiber towel to dry the surface afterward.
Now, prepare your cleaning solution. Mix a small amount of mild detergent or soap with warm water. You can also use rubbing alcohol or vinegar for this step, especially if you are dealing with stains. For vinegar, use one tablespoon per cup of water, and for rubbing alcohol, simply apply a small amount to the stain.
Next, start cleaning the plastic surface. Dip your clean cloth into the prepared solution and gently rub it in a circular motion around the scratch. Make sure to cover not only the scratched area but also its surrounding parts to ensure any dirt or grease is removed. If there are deep cuts or scratches, pay extra attention to getting any dirt and debris out of them.
Once you have cleaned the area thoroughly, dry it with a clean, dry cloth. You can use a microfiber towel for this step to ensure a streak-free finish. Make sure the plastic surface is completely dry before moving on to the next step of scratch removal.
If you are dealing with stains, there are a few additional steps you can take. For coffee or tomato stains, use rubbing alcohol or hand sanitizer, and then wash the area with warm water and dish detergent. For yellow or grass stains, try using lemons by rubbing the stain with half a lemon and letting it dry in the sun.

Use a mildly abrasive compound
To smooth out scratches on plastic, you can use a mildly abrasive compound, such as toothpaste, furniture polish, baking soda, or plastic polish. First, clean the plastic surface with a damp cloth, rubbing in a circular motion around the scratch. Dry the area to remove any dirt, which should make the process easier. Next, apply a mild abrasive to the scratch. For example, you can try squeezing out a small amount of toothpaste and spreading it over the scratch with a soft cloth or cotton ball. Gently rub in a circular motion, then rinse clean with water. You can also make a paste by combining equal parts water and baking soda in a glass bowl. Apply this mixture to the scratch and let it sit for about 10 minutes before wiping it away with a rag.
If you are dealing with deeper scratches, you may need to use a more abrasive method, such as wet sanding with micro-grit sandpaper. However, always start with the least abrasive method first to avoid causing further damage to the plastic. If you decide to try wet sanding, soak a piece of 800-grit wet/dry sandpaper in water until saturated. Use a gentle, circular motion to sand the area, being careful not to apply too much pressure to avoid creating new scratches. Rinse the sandpaper and the plastic surface between passes, and re-wet the sandpaper as needed. If traces of the scratch remain, move on to a finer grit sandpaper, such as 1000-grit, and repeat the process until the scratch is no longer visible.
After removing scratches with a mildly abrasive compound, you may need to restore shine to the plastic. You can do this by applying a small amount of plastic or metal polishing compound in circular motions with a clean, dry cloth. Repeat this process as needed until the plastic gleams as good as new.

Buff the scratch out
Buffing out scratches on plastic involves using a mildly abrasive compound to smooth out the surface. Before you begin, ensure that the surface is clean and free of dirt or debris.
Toothpaste is a mild abrasive that can be used to buff out light scratches on plastic. Apply a thin coating of toothpaste to the scratch using a soft cloth, then gently rub in a circular motion before rinsing and wiping clean.
Baking soda is another mildly abrasive compound that can be used to buff out scratches. Create a paste by mixing equal parts water and baking soda in a glass bowl. Apply the paste to the scratch and use a cloth or cotton ball to spread it over the affected area. Allow the paste to work for about 10 minutes, then wipe it away with a rag.
For deeper scratches, you may need to use sandpaper to buff out the scratch. Wet the sandpaper with water to avoid it being too abrasive, then gently rub over the scratch in a circular motion until the scratch disappears. Clean the area with a fresh cloth and allow it to dry. If the scratch is still visible, repeat the process with finer-grit sandpaper. Finish by polishing the area to blend it in with the rest of the surface.
It's important to note that if a scratch is too deep, it may not be possible to remove it completely, and you may need to replace the plastic item or seek professional help.

Sandpaper for deeper scratches
Sandpaper can be used to remove deeper scratches on plastic surfaces. Before using sandpaper, 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 ball to clean the damaged area.
Once the surface is clean, you can begin the process of sanding. It is important to use micro-grit sandpaper, as regular grit sandpaper is too harsh for plastic. The sandpaper should be dampened with water to prevent further damage to the item. Start with the lowest grit micro-grit sandpaper (360 grit) and soak the paper in water for several minutes until it is saturated. Using steady, gentle pressure, rub the scratched area in a 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.
After sanding, the area may look duller than the rest of the piece. To restore the shine, use a commercial plastic or metal polishing compound. Follow the directions on the label, or put a small dab of the compound on a clean, dry cloth and polish the dull area in small circles. Buff the area with a lint-free microfiber cloth and repeat until the shine is restored.
If the scratch is too deep, it may not be possible to remove it completely, and you may need to replace the plastic item.

Rinse and dry
Rinse the plastic surface with water to remove any residue from the scratch-removal process. It is important to rinse periodically during the scratch-removal process to observe your progress. 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.
After rinsing, dry the plastic surface with a microfiber cloth. Ensure that the cloth is clean and dry before using it to wipe down the plastic surface. If you are working on a matte finish, you can wipe it down with a wash rag and non-moisturizing Pledge.
If you used toothpaste to remove the scratches, rinsing with water and examining your work is an important step. It may take a few applications and some elbow grease before you get the desired results. Rinse and dry the surface after each attempt to accurately assess your progress.
If you used a baking soda paste, rinse the area with warm water and check the scratches. You may need to repeat the process several times before the scratch is completely gone. Rinse and dry the surface after each attempt to accurately evaluate your progress.
