My dish was slightly rusted after the first use in the dishwasher. My inquiry at Küchenprofi gave the stainless steel bowl is not suitable for the dishwasher. In particular, the use of vinegar in the bowl can not stand with the salt of the dishwasher. I should free with sandpaper the bowl from rust and no longer in the dishwasher stellen.Wenn you the model of Deluxe Küchenprofi for comparison draws, is there expressly Dishwasher. My own inquiries showed that only low-quality stainless steel has these problems.
