Can laundry detergent be used to wash a car?

[EthanDella]

No, laundry detergent should not be used when washing a car, as it can damage the car's paint. It is essential to use specialized car cleaning agents and follow the correct washing methods to ensure the paint remains undamaged. If proper care is not taken during regular car usage, the vehicle's paint can easily become damaged. Damage to the car's paint can affect its overall appearance. The car's paint consists of four layers, from the inside out: the electrocoat layer, the primer layer, the basecoat layer, and the clearcoat layer. After the car body is fully assembled, robots immerse it in an electrocoating bath, forming the electrocoat layer on the surface. The primary function of the electrocoat layer is to prevent rust on the car body. Once the electrocoat layer is applied, robots spray the primer layer, which also helps prevent rust and enhances adhesion to the next paint layer. Above the primer layer is the basecoat layer, which provides the car's color. The various colors we see on cars are due to this layer. The clearcoat layer is the outermost paint layer, protecting the basecoat and enhancing the paint's gloss. Most minor scratches typically remain on the clearcoat layer.
