Much like the others have stated here, mine also oxidized after being put in the dishwasher for the first time.  Have hand washed it for a few years but the one time in the dishwasher(as stated is safe) it has been rendered useless.  It now has a slivery/greyish film that come off and I do not want to mix anything and put this finish in my food.
Needs to be redesigned or ensure the finish does not WASH off
