What car wash detergent should I use for washing my car myself?

[LeEthan]

For washing your car yourself, use a neutral car wash detergent, preferably one containing water wax ingredients. Car wash detergents are generally neutral and won't harm your hands or the paint surface. The worst thing to use when washing your car is strongly alkaline detergents or soap powder, as although they have strong cleaning power, they also cause significant damage. Frequent use of such detergents will quickly erode the glossy surface of the car body and accelerate the aging of rubber components, tires, windows, etc. Car wash detergents usually also contain natural car wax and natural anti-static ingredients for the car body, which can give the car a clean and shiny appearance and provide a certain elasticity to the paint surface, so that ordinary small flying sand generally won't scratch the paint surface.
