Is 40bar Water Pressure Enough for Car Washing?

[AlexAnn]

40bar water pressure is not sufficient for car washing. The recommended pressure range is between 60 to 80bar. Water pressure within this range can effectively remove dirt and sludge from the vehicle's body without causing damage to the paint. Below are some precautions for car washing: Use Soft Water: Avoid using any water other than soft water, including hot water, alkaline water, or water with high hardness. These substances can damage the paint surface, leaving marks and a thin film on the car's body after drying. Avoid Detergents: While there may be highly corrosive stains on the car body, such as asphalt, oil stains, bird droppings, or insect feces that are difficult to clean, never use laundry detergent, stain removers, or low-quality soap during washing. These cleaning agents contain alkali, which can strip the oils from the paint surface and accelerate paint aging.
