Can toothpaste be used to clean yellowed car paint?

[OLena]

If the yellowing is slight, toothpaste can be used for polishing. Methods for daily protection of car paint: 1. Remove dust from the car body: In daily car use, promptly remove dust from the car body to minimize the adsorption of dust caused by static electricity. 2. Rinse promptly after rain: 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 acidic substances behind. If not rinsed with clean water promptly, these substances can damage the paint over time. 3. Precautions: Pay special attention when washing the car—do not wash it immediately after a long trip. The correct 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 under intense sunlight can act like a magnifying glass and harm the car's paint.
