What can be used to wash a car at home?
1 Answers
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.
