I really love my KitchenAid mixer and I'm always careful not to put my attachments in the dishwasher. I pulled out my whip to begin my fall holiday baking season only to find that the base of it is coated with some gray residue that smudges off on my fingers. What is going on with this product???? This attachment costs too much money to look this way after only one year. This whip has been stored in the bag covering my mixer along with my other attachments. Because of this residue I'm afraid to use it for my baking this year.
