I own a merchandising company that sells those same cups. I'm not sure which exact one you have, but if it's like this one, yes, they are dishwasher safe. That doesn't necessarily mean the logo might not eventually start to fade, but they are safe in the sense that it's not detrimental to your health or anything.
