I have wanted the lift bowl mixer for many years.  I finally got the Red one KG25HOXER for Christmas.  I loved it and took very good care of it not to wash the blades.  however, my husband was trying to surprise me and used my mixer. He put the blades in the dishwasher and now they are covered in the black residue.  I had to throw them away.  Wow what a SURPRISE that was.
