I'll start by telling you what prompted me to post this thread. My wonderful, amazing husband whom I love dearly put my Vitamix container in the dishwasher, a big no-no according to the company. It still works but it always looks dirty, no matter how much I scrub it (by hand, of course). I have long since forgiven DH, but I am reminded of his misdeed whenever I use my Vitamix, which is often several times a day.
What have you put in the dishwasher against the company's guidelines? How did it turn out?
