you can't use detergent in car washing. Generally, the foaming ability of detergent is not as strong as that of car washing, because detergent is to ensure fast washing and less residue, so detergent usually adds a small amount of defoamer. However, car washing requires a lot of foam. Foam can make the contact area between car wash liquid and stains larger and easier to clean. When washing the car, the car wash liquid needs to be attached to the paint surface for as long as possible to ensure adequate lubrication when washing the car. These two requirements, detergent is difficult to achieve.

Detergents are mainly designed for tableware, fruits and vegetables. It can also clean some kitchen utensils and clothes. The cleaning ingredients in washing powder are generally sodium sulfonate, sodium fatty alcohol ether sulfate, foaming agent, etc. Belonging to alkaline products. Long-term use will hurt hands, such as hand peeling.

Harm of detergent and car washing: Alkaline substances can react with other substances, and so can cars. If they act on the paint surface for a long time, its alkalinity will corrode the rubber strip of the car body and make it age or break, the paint surface of the car will be easily damaged, and the car itself will lose its original luster and even turn white. So it is not appropriate to wash the car with washing powder and detergent.
