Is 20bar Water Pressure Enough for Car Washing?
2 Answers
20bar water pressure is sufficient for car washing. Here is the relevant information: 1. Optimal water pressure: The best water pressure for car washing is around 60 to 80 kilograms. Generally, water pressure within this range can effectively remove dirt and sludge from the car body without damaging the paint. Excessive washing pressure can cause the water stream to violently impact the car body, leading to damage. When washing parts like wipers and rearview mirrors, excessive pressure may also cause damage. 2. High water pressure: Compared to low water pressure, high water pressure can clean the car more thoroughly and significantly reduce washing time. However, it is still better to use appropriate water pressure for regular car washing.
I think 20 bar water pressure is completely sufficient for car washing. Normally, I use a high-pressure car wash gun within this pressure range, which effectively removes dirt, dust, and most stains from the car's surface—far better than a household faucet. The key is to use it correctly: avoid direct high-pressure spraying at close range on the paint to prevent damage to the paint or wax layer. I recommend first lowering the pressure to wet the entire car body, then gradually increasing the pressure to clean stubborn dirt on the wheels and tires. Also, pay attention to the water flow angle to prevent water from shooting into door gaps and causing water accumulation. Combined with car wash soap to soften stains, 20 bar is safe and efficient enough for daily car washing tasks, saving time, effort, and money. Remember to dry the car promptly after washing to prevent water spots.
