It PROBABLY isn't anything to worry however it was very shocking to see the
amount of crap growing inside my dishwasher. I assume that it escapes the
jets of water due to its location. There might be a niche were the
temperatures don't reach as high as the rest of the dishwasher. I suppose
there are people who work for companies like Kitchenaid who know exactly
what this stuff is.
