Can Dishwashing Detergent Be Used to Wash a Car?

[StAnderson]

Dishwashing detergent should not be used to wash a car. Dishwashing detergent is an alkaline cleaning agent and can cause significant damage to the car's paint. If used repeatedly over time, the car's surface will gradually lose its shine. The harm caused by using dishwashing detergent to wash a car includes: Damage to the Paint: Dishwashing detergent is effective at removing grease, which also means it can strip away the protective wax on the car's surface. Car wax serves to protect the paint, and once removed, the paint becomes vulnerable to damage. The car may lose its original luster and even develop a whitish appearance. Corrosion of Rubber Seals: Being alkaline, dishwashing detergent can corrode the rubber protective strips on the car, causing them to discolor, lose elasticity, or even break. For this reason, professional car washes use pH-neutral cleaning products that help protect the car's surfaces. Difficulty in Thorough Cleaning: Dishwashing detergent produces excessive foam, and when washing the car yourself, there are often limitations in thoroughness. This can result in streaks and residue left on the car's surface after drying, affecting its appearance.
