What kind of foam should be used for washing cars at home?

[OCamilla]

When washing your car at home, you should use foam made by diluting specialized car wash liquid in the correct ratio. The benefits of specialized car wash liquid and precautions for car washing: Benefits of specialized car wash liquid: Specialized car wash liquid contains water wax components and has a neutral pH value, which does not erode the car's surface. It also nourishes and maintains the car paint, ensuring that the paint is not damaged and the car becomes shinier with each wash. Precautions for car washing: Do not use strong alkaline detergents or soap powder to wash the car. Although they have strong cleaning power, they can cause significant damage, easily eroding the gloss of the car's surface paint and accelerating the aging of rubber parts, windows, and tires.
