What issues should be paid attention to when washing a car?

When washing a car, avoid randomly adding detergents, avoid using high-pressure water streams to rinse the car body, and avoid using water other than soft water for cleaning. The following are detailed explanations: Avoid randomly adding detergents: Do not use laundry detergent, stain remover, or low-quality soap when cleaning. These detergents contain alkali, which can wash away the oils in the paint surface and accelerate paint aging. Therefore, detergents are generally not added when washing a car. Avoid using high-pressure water streams to rinse the car body: Excessive water pressure can damage the car's paint surface. If there is hard dust or mud on the car body, first moisten it with water and then rinse it off. Use dispersed water streams for spraying. Avoid using water other than soft water for cleaning: This includes hot water, alkaline water, and water with high hardness, as these substances can damage the paint. Using hard water for cleaning will leave marks and a film on the car body surface after drying.
As a car enthusiast who treats my vehicle like my life, I always pay special attention to several pitfalls during car washing. Never wash your car under direct sunlight - water droplets can act like magnifying glasses and bake spots into the paint, which are expensive to repair. Water temperature matters too; don't spray cold water on a hot engine bay right after highway driving as rapid temperature changes can warp metal components. Never cheap out on cleaning agents by buying strong alkaline solutions - I once ruined my wheel hub coating with some mystery liquid. Avoid using old clothes for drying; invest in microfiber towels instead, or you'll end up with swirl marks all over the paint. Don't neglect hard-to-reach areas like the undercarriage and door seams - unclog those drainage holes before rainy season or your car might become an aquarium. Finally, remember to take a short drive immediately to dry the brake discs, or you risk rust and seizure troubles.
