1. Take some egg whites first, then dip them with toothpicks and smear them on the scratches. Be careful when smearing, otherwise it will affect the effect. Wait until the egg white is almost dry, and then gently press the scratched part to make the two sides of the incision stick together tightly. This method only applies to black.

2. Squeeze a proper amount of toothpaste on the wet rag, and wipe the scratches repeatedly, and the scratches will gradually fade away until they disappear.

3. If the scratch is small, quickly wipe it with a rag dipped in a proper amount of detergent; If the scratch is large, it is necessary to polish the scratch with sand to make it lighter, and then completely eliminate the scratch with detergent.

4. Scratch stickers also help to remove scratches on plastics. Apply the scraping paste to the rag and wipe the scratches on the plastic repeatedly. If the scratch is shallow, you can wipe it off several times. If the scratch is deep, you can repair the plastic scratch by rubbing it several times.
