The appearance of small yellow spots on the car is due to the rusting of iron particles adsorbed on the car surface. If there are iron particles in the air, the static electricity generated on the car surface will attract them. Once it rains, the iron particles on the car will rust, forming small yellow spots.
Tips for Removing Yellow Stains on White Cars
If there are only a few yellow spots on the car, toothpaste can be used to remove them. Squeeze some toothpaste onto a cloth and wipe the yellow spots. The stains will be quickly erased.
If there are a larger number of stubborn yellow stains, iron particle remover or volcanic mud can be used.
Iron Particle Remover:
Iron particle removers are available online for around 20 yuan. Before using, rinse the car body with water, dry it with a towel, spray the iron particle remover, wait for 3-5 minutes, then wipe with a sponge. After the iron particles react with the cleaner, rinse it off.
Volcanic Mud:
Soak the volcanic mud in water before use. Rinse the car body with water, apply a layer of car wash liquid for lubrication, and then wipe with the softened volcanic mud. While wiping, use a water hose to rinse until the yellow spots disappear.
Preventing Yellow Stains on Cars
1：Park indoors: Park the car indoors to reduce exposure to sunlight. If there's no garage, consider building a car shed.
2：Regular cleaning: Clean the car regularly to remove dust, iron particles, bird droppings, and other debris from the paint surface, providing a certain level of protection to the car paint.
3：Regular waxing: Waxing the car periodically reduces the damage from ultraviolet rays and prevents the paint from corroding due to acid rain.
