Our mugs are coated in the Orca sublimation coating which means the mugs are fully dishwasher safe and microwave safe. When we say dishwasher safe we mean they can be washed in any dishwasher with any dishwasher tablet. We have tested these using the Finish PowerBall dishwasher tablet for months with no deterioration in quality.
Some companies sell "dishwasher safe" mugs which are okay so long as they are not washed above a certain temperature or so long as you don't use a specific type of dishwasher tablet (such as the Powerball). Our mugs do not have such a restriction so we can assure our customers that the image will not fade.
