Dishwashers are where beautiful things go to die. I love my dishwasher (Miele, and soooooo quiet), but if its a) beautiful, b) made outta wood or c) only kinda sorta gets “dirty” (in the sense that a tamper only ever touches coffee grounds, it’s not like I need it for surgical procedures), then I hand wash as needed.
And you just said in the opening post that you skipped the wood one because it wasn’t dishwasher safe.
But I will concede that it’s just a tamper; as long as it gets the job done, who cares?
Also, I might be slightly jealous that my machine has a tamper that clips to the chassis with a magnet. I think I want a flashy tamper, but I don’t want to make the current one obsolete. First world problems, amiright?
ETA: and KNIVES! Never put knives in the dishwasher!
