Methods for cleaning black spots on white cars: 1. Go to a car wash; 2. DIY cleaning: First use foam cleaner or tar remover to clean, then polish, and finally apply wax. Car maintenance methods: 1. After heavy rain, wash the car promptly to prevent mud accumulation in the lower gaps; 2. In rainy seasons, perform a paint surface treatment—simple waxing or more durable and effective sealing; 3.

I recently dealt with the issue of white paint being plagued by black spots and have gained some insights from washing it myself a few times. First, rinse the car body with a water gun, spending extra time on areas with black spots. Then, mix car wash soap into foam water and gently scrub the spots with a sponge, being careful not to apply too much pressure to avoid scratching the paint. For tar spots, spray tar remover and wait three minutes before wiping. For stubborn rust spots, use clay to slowly rub them off. Finally, rinse thoroughly and dry immediately, remembering to apply a layer of wax to protect the paint. The whole process requires patience—avoid using hard objects like steel wool. Washing the car weekly can effectively prevent black spots from appearing.
