Can Toothpaste Be Used to Clean Yellowed Car Paint?

[Cardoso]

If the yellowing is slight, toothpaste can be used for polishing. Methods for daily car paint protection: 1. In daily car use: promptly remove dust from the car body to minimize the adsorption of dust due to static electricity; 2. Rinse promptly after rain: In modern society, especially in large cities, the chance of acid rain is relatively high. However, after heavy rain, rain stains on the car body are continuously dried by the sun, leaving behind acidic substances. If not rinsed off with clean water promptly, these substances can damage the paint surface over time; 3. Pay special attention when washing the car: Do not wash the car immediately after a long trip. The normal practice is to wait until the engine cools down before washing to avoid sudden cold water causing damage to the vehicle and to prevent cleaning agents from drying and leaving marks. Additionally, avoid washing the car under direct sunlight or high temperatures for similar reasons, as water droplets can act like magnifying glasses under the sun, potentially harming the car's paint surface.
