Yes, washing machine detergents and shower soaps are generally too aggressive for car washing. Let's understand why:
Chemical Formulation: Washing machine detergents and shower soaps are formulated for cleaning clothes and human skin, respectively. They often contain chemicals and additives that can be harsh on automotive paint and finishes.
pH Levels: Car paint requires a specific pH balance to maintain its integrity. Washing machine detergents and shower soaps may have pH levels that are not suitable for automotive surfaces. Using them on your car can cause the paint to fade, dull, or even peel over time.
Abrasive Particles: Some washing machine detergents and shower soaps may contain abrasive particles to help with cleaning, which can scratch and damage the car's paint and clear coat.
Lack of Protective Additives: Car wash shampoos are designed with special additives that help protect the paint and provide a lubricated surface during the washing process. Regular detergents and soaps lack these protective additives, leaving the paint vulnerable to damage during washing.
For car washing, it's best to use products specifically formulated for automotive cleaning, such as:
Car Wash Shampoo: Car wash shampoos are designed to be gentle on automotive paint while effectively removing dirt and grime. They have the right pH balance and often include protective additives to enhance the paint's shine and protect it from damage.
Microfiber Cloths: When washing your car, use soft and clean microfiber cloths or mitts to avoid scratches and swirl marks on the paint surface.
Hose or Pressure Washer: Use a gentle stream of water from a hose or pressure washer (set on low pressure) to rinse off the car before and after washing.
Proper Technique: Always use a two-bucket method, where one bucket contains the soapy water and the other clean water for rinsing the mitt or cloth to avoid transferring dirt back to the car's surface.
Using the right car wash products and following the correct washing technique will help maintain your car's appearance and protect its paint and finish from unnecessary damage.
