DISHWASHER SAFE: Our mugs are dishwsher safe and our inks are Heat-Set and will not fade. However, we thoroughly recommend washing by hand, as this is the safest and most effective method for all mugs. If washing in a dishwasher, be sure to keep all mugs from touching each another object in the dishwasher to avoid scratches. NEVER place mugs on the bottom shelf of the dishwasher. Do NOT scratch the print with metal objects.
