You should never use regular household cleaning products to wash a car.
Why? Dish soap contains degreasers that can damage the vehicle’s surface and cause premature paint fading over time.
On the other hand, car soaps have been created specifically to clean and protect automotive paint. Most of them are mildly alkaline (ph 7.1-8) which helps in breaking down dirt, dust, and tar. But if the product is too alkaline or too acidic, it can easily damage finishing products, rubber seals, plastic, and metal trims.
To reduce the risk of damaging paint and other vehicle components, we recommend using a ph-balanced car soap. Other characteristics you want to look for are heavy foaming, good lubricity, and biodegradability. Avoid “waterless” and “2-in-1 wash & wax” products - don’t fall for the marketing gimmicks.
SRB pink foam shampoo is a professional-grade soap for cleaning cars, boats, and other hard surfaces. It eases wax and grease removal and improves the longevity of protective coatings - all that while providing a smooth feel. This product contains no ammonia or caustic chemicals that could damage the surface of your ride or the environment.
