We highly recommend rinsing your exhaust with water every time you wash your car to remove contaminants, road grime, and salt. Salt is very corrosive and can cause surface rust if left on your exhaust, suspension, and other components. If you’re going through an automatic car wash, definitely consider an option that washes your undercarriage! To maintain the tips, we recommend non aggressive cleaners without and type of grit to leave the finish intact. Wash your tips every time you wash your car.
