What can be used to wash a car at home?

You can use dishwashing liquid, laundry detergent, or car wash soap to wash your car at home. The specific details are as follows: Dishwashing liquid for car washing: The main ingredient of dishwashing liquid is primarily sulfonic acid, and most dishwashing liquids are alkaline products. Although some dishwashing liquids are neutral, long-term use can harm your hands, such as causing peeling. Laundry detergent for car washing: Due to its strong alkalinity, the pH value of laundry detergent far exceeds what car paint can tolerate. The suitable pH range for car paint is approximately 6.5-6.8, while the pH of laundry detergent generally exceeds 10. Additionally, laundry detergent often contains a large amount of inorganic salts, such as sodium silicate, soda ash, and anhydrous sodium sulfate, which often do not dissolve well and remain as particles in the liquid, potentially damaging the paint surface during washing and causing fine scratches. Car wash soap for car washing: The main cleaning ingredients in domestic car wash soaps are natural plant-derived surfactants. Additionally, car wash soap usually contains natural car wax and natural anti-static components for the car body. Car wash soap is generally neutral and will not harm your hands or the paint surface. Since it contains natural wax, it can give the car body a clean and shiny appearance and provide the paint surface with some elasticity, preventing minor sand particles from scratching the paint surface.

I really enjoy washing my car at home, finding it both economical and convenient, plus I can do it entirely at my own pace. My usual tools include a regular hose, a bucket of water with dedicated car shampoo, a soft sponge, and a few microfiber drying cloths. First, I rinse the car's surface with soft water to remove loose dust. Then, I mix the soapy water in the bucket and gently scrub the body and wheels from top to bottom with the sponge, being careful not to press too hard to avoid scratches. Next, I rinse off all the foam thoroughly, ensuring no residue remains. For drying, I use microfiber cloths on the windows and roof, while letting the rest air-dry naturally. I avoid washing under direct sunlight to prevent water spots. Remember to use car-specific shampoo—never substitute with household soap or dish detergent, as they can dull the paint and even corrode the rustproof coating. The whole process takes about half an hour, and I do it weekly. My car always looks shiny, plus I save money and time by skipping the car wash. It’s also eco-friendly with minimal water usage, which gives me great satisfaction.

Since childhood, I've been accustomed to conserving resources, and even when washing my car at home, I prioritize environmental considerations. I typically use a recyclable bucket filled halfway with rainwater or tap water, adding biodegradable car wash soap, and carefully scrub with a soft sponge. During rinsing, I use a low water flow to control the amount of water or collect the used water to irrigate the garden, minimizing waste. For drying, I repurpose old towels cut into microfiber cloths. It's essential to choose specialized car wash products to protect the paint and avoid harsh chemicals that pollute the environment. Although this method takes a bit longer—around 20 minutes—the water consumption is very low, aiding in water conservation. Keeping the car clean also extends its lifespan, and the money saved can be used for other necessities, making it a responsible choice for both the planet and myself.

I'm the type who's always pressed for time, so washing my car at home has to be quick and efficient. I start by rinsing the car body with a hose to remove dust, then buy a ready-made car wash solution, squeeze it onto a wet sponge, and wipe the entire car from top to bottom to avoid splashing mud. After wiping, I rinse off the foam and dry the surface with a soft cloth. The whole process doesn't require tools costing more than 10 yuan, takes just 15 minutes, keeps the car clean and saves money—the key is to avoid any sloppy movements.
