Does High-Pressure Water Gun Car Washing Damage the Car?
1 Answers
Yes, it does. High-pressure water gun car washing can damage the car paint. When using a high-pressure water gun, excessive water pressure and improper operation can easily cause sand and stones on the car to scratch the surface, leading to abnormal wear of the paint. If the paint is already slightly damaged, the high-pressure water gun can enlarge the damage or even wash away wax, crystal coatings, or protective films. Here are some precautions for car washing: 1. Pre-washing is crucial: Cars often have a lot of dust and mud. Before washing, it's important to add a pre-wash step, which involves using professional equipment to spray a special pre-wash solution on the car body and waiting for one or two minutes. After soaking, most of the dirt will detach from the paint, making it safer to rinse with the water gun. 2. Follow a proper washing sequence: Start with areas that have less dust and mud, such as the roof, hood, and trunk lid. Cleaning from top to bottom helps prevent scratches, and always scrub in the same direction. 3. Choose the right water temperature: After driving for a while, the car is in a high-temperature state, and using cold water to wash it at this time is not advisable. Even if the car hasn't been driven for long but has been exposed to sunlight for a significant time, washing it immediately with cold water can cause the paint to age due to thermal expansion and contraction.
