For best results it is recommended to wash the car every two weeks to avoid excessive soiling. Washing your car without causing scratches is best done with the 2 bucket method. Avoid car washes, hand car wash brushes and cleaners with a high pH value. Avoid washing in direct sunlight to minimize streaks and water spots.
Use products from the same manufacturer as the coating applied to the car paint. These products are best coordinated with each other.
