How to Repair Car Scratches with Toothpaste?
2 Answers
Method for repairing car scratches with toothpaste: Use a soft cloth or sponge to apply toothpaste and gently polish the scratched area. Be careful not to apply excessive force to avoid large-scale polishing that may cause a matte finish and affect visual appearance. Toothpaste has a polishing effect and can repair some minor scratches. However, it is not recommended for car owners to use toothpaste for repairs, as improper handling may result in more severe scratches. If scratches appear on the car's paint surface, it is advisable to visit a car beauty center for polishing. The car's paint surface consists of four layers, from the inside out: the electrophoretic layer, the middle coating layer, the color paint layer, and the clear coat layer. After the car body is assembled, robots immerse the entire body in an electrophoretic pool to form the electrophoretic layer, which serves as an anti-rust barrier. The middle coating layer is the second layer of paint, which also provides anti-rust protection and enhances adhesion to the next paint layer. The third layer is the color paint layer, which displays the various car body colors visible in daily life. The fourth layer is the clear coat layer, which protects the paint and enhances its glossiness.
Once, there was a fine scratch near the door handle of my family car. I simply squeezed some regular white toothpaste onto a soft cloth and gently rubbed it in circular motions for about ten minutes. Some ingredients in toothpaste can indeed polish away minor scratches on the clear coat surface. After rubbing, make sure to thoroughly clean off any residue with a clean, damp cloth. Be careful not to use toothpaste with granules, as it might make the scratch more noticeable. This minor repair method is particularly suitable for those long, thin scratches caused by neighboring car doors hitting yours—it saves both money and time. However, if you can feel any unevenness or see the primer color through the scratch, this method won’t work.
