Received a 5 quart stand mixer for Christmas. The flat beater was put in the dishwasher this morning-I normally hand wash but my kids threw it in the dishwasher to help me out-now it’s ruined. The finish is completely gone and a black powdery substance remains. The kids feel guilty but it’s not their fault as the attachment was supposed to be dishwasher safe. I’m not happy and neither is my husband who spent hundreds of dollars on this mixer. Do not recommend purchase.
