Can Shampoo Really Be Used to Wash a Car?

[AnnaAnn]

Shampoo cannot be used to wash a car unless there is no car wash liquid available, in which case shampoo can be considered as an alternative. Unlike laundry detergent, dish soap, or body wash, shampoo is weakly acidic and causes less damage to car paint. However, it should not be used frequently, as regular use can still harm the paint. Here are some car washing precautions: Avoid washing a hot car with cold water: After high-speed driving or prolonged exposure to the sun, the surface temperature of the car paint is very high. If cold water is used at this time, the paint surface may be damaged, and in severe cases, it can lead to cracking. Washing once a week is optimal: Washing the car too frequently is unnecessary. Generally, washing once every 7–10 days is sufficient, as frequent washing can accelerate paint oxidation. However, this is not absolute. If the car body is contaminated with mud, rainwater, bird droppings, etc., the owner should clean the vehicle as soon as possible to avoid corrosion of the paint.
