First, use a soft damp towel to clean the interior plastic panel. Then shake the car-specific dashboard wax and spray it evenly on the interior plastic panel. For more severe scratches on car interior plastic, the repair method involves sanding and polishing the surface of the plastic. For minor scratches on car interior plastic, clean the scratched area and then use professional materials to spray it. If the scratches are on genuine leather car interiors, the repair mainly focuses on the color layer, and specialized interior leather paint is generally used for repair.

A few days ago I just finished dealing with the plastic scratches on my car and discovered several practical methods. For minor scratches, you can slowly polish them with toothpaste and a soft cloth, just like removing scratches from a screen. Be sure to use plain white toothpaste, not the gel type. If the scratches are a bit deeper, there's a plastic repair paste available at car detailing shops that works exceptionally well—once applied and dried, the scratches are barely noticeable. The scratches on my car's air vents were treated with a heat gun and a scraper, but you have to be very careful not to set the temperature too high to avoid warping. Regular maintenance is also crucial; spraying some interior protectant periodically can help prevent new scratches. Lastly, I'd like to remind everyone never to use alcohol or strong solvents to clean plastic parts, as that will only make the surface rougher.

As someone who frequently handles interior refurbishment, I believe scratch repair depends on the severity. Superficial scratches can be fixed with an eraser, which works especially well for fine lines near door handles. For medium-depth scratches, I recommend using professional plastic restorer, but remember to clean surface grease before application. If the scratch reaches the primer, gently sand it with 600-grit sandpaper first, then apply color—interior touch-up pens sold on Taobao are very convenient. Avoid casually tossing keys onto the dashboard while driving, as metal edges easily scratch plastic parts. During summer heat when plastics soften, they're more prone to marks, so try parking in shaded areas whenever possible.

I've seen too many cases where improper repairs made the interior look worse. Minor scratches are actually nothing to worry about; plastic parts naturally show signs of wear over time. If you really want to address them, even a bottle of shoe polish from the supermarket can serve as an emergency fix—black shoe polish works surprisingly well on dark-colored interiors. Just remember, never use steel wool or hard brushes, as they will definitely cause permanent damage. If the dashboard has severe glare issues, applying a scratch-resistant film is the most hassle-free solution. For scratches near the airbag, it's strongly recommended to consult a professional, as DIY attempts might interfere with the airbag deployment.

I always keep an interior repair pen in the glove box, as treating scratches immediately yields the best results. The repair process involves three steps: first, clean the surface with an alcohol wipe, then apply the repair solution in small dots, and finally polish in circular motions with a microfiber cloth. For linear scratches, always follow the grain direction—never rub across it. Regular use of dashboard wax can create a protective layer; my friend's car interior still looks brand new after five years. For car mod enthusiasts, note that while carbon fiber wraps look cool, removing them often leaves stubborn adhesive marks that are harder to fix.

After fixing my kid's toy car last time, it suddenly occurred to me that similar methods could be used for interior scratches. Use a hairdryer on low heat, blow at the scratch for half a minute to soften the plastic, then gently smooth it out with the back of a smooth spoon. After cooling, it basically returns to its original state—this trick works particularly well on door panel storage compartments. For white scratches, applying some hand cream and wiping it off after half an hour is very effective. When cleaning the interior, always choose a neutral cleaner; strongly alkaline ones can make the plastic turn white. Light-colored interiors are recommended to be maintained monthly, while dark-colored ones can be done every two to three months.
