First Step - Safe Clean

First step is to wash and dry the car, or at least the area you will be working on. Then use the Clean Detail spray to give a further clean of the chromed surface. Spray it quite liberally onto the chrome and then wipe it away with the higher pile/plush side of the Big Softie microfibre cloth. This should help remove a lot of the embedded dirt and built up grime that normal washing will not always touch.
