The discoloration you’re experiencing typically is a result of hard water staining. As the water evaporates while drying, excessive mineral content in the water is left behind, leaving visible residue in the form of spots.  Typically, this is more visible on our darker colored DuraCoat colors, however it can occur on any of our DuraCoat Ramblers.

To remove hard water spots from your Rambler, try soaking the Rambler in piping hot water for a few hours and then drying thoroughly.  The heat will help re-dissolve those minerals back in the water, removing the spots and getting your Rambler looking brand new again!  I typically do this in the sink, but make sure you take the proper safety precautions to stay safe when handling hot water.  Alternatively, make sure that your dishwasher is set to the highest water temperature setting to help prevent this from occurring in the future.
