I used my flat beater for the first time.  I have had my mixer for a few years and I really don't like it so Iv'e never used the paddle.  I put it in the dishwasher and it did come out completely black & in my opinion, ruined.  I had no idea that it needed to be hand washed.
Who puts out a product in this day in age that can't go in the dishwasher?  Very disappointed.
