All soaped and scrubbed up, this is where the Stain-Less Filter really goes to work; washing down is, for the most part, all that is needed. Outside drying the chrome and the windows, we did not need to dry the rest of our Carson Trailer at all. One tip: Hold the hose without a nozzle close to the surface of the RV when rinsing. This will create a sheet of water that will in turn reduce the amount of water drops left on the rig. This trick will lessen water spots and dry times substantially.
