What can be used instead of car wash liquid?

Use some neutral detergents, such as shampoo, shower gel and hand sanitizer.

Never use washing powder or detergent instead of car wash liquid. You can use some neutral detergents temporarily, such as shampoo, shower gel, hand sanitizer, etc., but don't use them for a long time.

This is because washing powder is an alkaline detergent, which is very harmful to car paint. If you wash the car with washing powder for a long time, the surface of the car will gradually lose its luster. Detergent has the function of dewaxing while removing stains. In the long run, the car paint will lose its luster.

Extended data:

The main cleaning component of car wash liquid is surfactant extracted from natural plants, which is the main component of shampoo in China. In addition, car wash fluids are generally added with natural car wax, which is a natural component that can drive away static electricity on the car body. Car wash liquid is generally neutral and won't hurt hands and paint.

You must choose the right car wash liquid for car washing. Alkaline detergent or soap powder is the most taboo for car washing, because although they have strong detergency, they are also harmful. If they are often used to wash cars, the light on the surface of the car body will be eroded quickly, and the aging of rubber parts, tires, windows and so on will be accelerated.
