Does washing a car with river water cause damage to the car?

[DelLucia]

Washing a car with river water can cause damage. Firstly, river water inevitably contains solid substances such as sand and mud, which can easily clog the car's internal components. Secondly, during the washing process, oil and dirt may flow out, polluting the river water. Therefore, cars are generally washed at auto beauty shops. Steps for washing a car at a beauty shop: 1. Use a water gun to rinse the car body, following the sequence from the roof to the body and then to the undercarriage; 2. Evenly cover the car's paint surface with foam; 3. Use a sponge to wipe the upper and lower parts of the car; 4. Rinse off the foam from the car body with a water gun, and use a specialized squeegee to remove water droplets from the car body; 5. Clean the interior of the car.

I once tried washing my spouse's car with river water to save some money, but soon after, fine scratches and spots appeared on the paint. It turned out that the sand and impurities in the river water were rubbing against the surface. Over time, rainwater seeped in, causing the roof to rust, and the repairs cost several hundred dollars. River water can also carry pollutants like fertilizers or industrial waste, which can corrode the car's metal parts and clog the window drainage holes. Now, I always use professional car wash services. Although it's more expensive, it's worth it for long-term car protection. Don't make the same mistake I did when I was young and tried to save a few bucks.

I'm quite particular about my car. When I first bought my new car, I rushed to wash it with river water, only to find water stains and scratches the next day. It scared me so much that I immediately went to research. River water contains fine sand and stone particles, which can wear down the car paint like sandpaper. There may also be corrosive substances like salt, accelerating rust on the wheels and chassis. Even worse, unclean water can leave behind bacteria, causing unpleasant odors both inside and outside the car. Now I use tap water or go to a car wash station—safe and worry-free. I really regret that experiment.

Washing cars with river water poses significant hazards. As an environmental advocate, this issue deeply concerns me. The sediment not only scratches the car's surface but can also clog drainage systems, leading to water accumulation and rust. River water often contains chemical pollutants like pesticides or heavy metals, which damage the paint and metal components. Over time, this reduces the car's value and harms the environment. Personally, I recommend using filtered water or professional car wash services to protect your vehicle while minimizing pollution sources.
