How to Treat Car Scratches with Toothpaste?

Methods for treating car scratches with toothpaste: 1. Squeeze out an appropriate amount of toothpaste and apply it to the car body; 2. Use a scouring pad to gently rub the car body; 3. Wipe the car body clean with a damp cloth. Toothpaste has a polishing effect and can repair some minor scratches, but it is not recommended for car owners to use toothpaste for repair, as improper operation may cause more severe scratches. A car's paint surface consists of four layers, from the inside out: the electrocoat layer, the primer layer, the basecoat layer, and the clearcoat layer. Most minor scratches usually appear on the clearcoat layer, and simple polishing can remove these scratches. However, frequent polishing is not advised, as it will reduce the thickness of the clearcoat layer and, over time, diminish the gloss of the car's paint surface.
I usually handle minor issues myself. For light scratches on the car, you can try using toothpaste. First, wash the car to ensure the scratched area is free of dust. Then, use a clean soft cloth to apply a small amount of white toothpaste to the scratch, gently rubbing in one direction in small circular motions without applying too much pressure. After a few minutes, rinse it off with water. Remember, this method only works for superficial light scratches—it may not be effective for deep scratches or metallic paint and could potentially damage the finish. I’ve tried it a few times, and it temporarily makes the scratches less noticeable, but the effect doesn’t last long. Afterward, it’s advisable to apply car wax for protection, and regular washing is recommended to prevent new scratches. In the long run, professional polishing or repainting is the more reliable solution, especially for cars frequently exposed to the elements—maintaining the bodywork is crucial. Safety first: if the scratch is large or in a critical area, it’s best to have it checked at a professional auto repair shop to avoid affecting driving safety.
