I've had my mixer since the early 90's.  I use it alot lol. Over the years my white coated paddle beater attachment started chipping away.  It was time for a replacement.  I found this burnished paddle beater and thought no more chipping!  Well, the trade off is gross gray residue.  I threw out my batter the first time it happened (which is a bummer since I bake from scratch :(  ).  I have handwashed this thing a billion times.  Sometimes you get gray residue sometimes you don't.  It's a real pain in the you know what to have to repeatedly wash and dry your beater before use to make sure it doesn't leave gray residue.  Please fix this!!!
