In general, our mugs themselves are dishwasher safe: our all-white mugs and our Morph or Chameleon coffee mugs. Our mug decorations, however, are not and for best results and to maintain image quality, we strongly suggest Hand Washing them and not to wash them with the dish washer. We would like to caution you that washing our mugs in a dishwasher (with a high dryer setting) might cause a premature fading of the decoration or might completely wash it off.
