I have an ancient Whirlpool dishwasher that started coating the dishes with black particulates. I cleaned the filter as well as possible, no improvement. Then, I remembered an experienced landlord suggested running a cup of CLR thru any dishwasher experiencing problems. I used a half cup of CLR, no other soap, and a hot wash.
Problem solved, the dishes are sparkling and the inside of the dishwasher looks cleaner. Cost about $5.25 for a 28 ounce bottle. No idea what is in CLR, but it seems to be a good cleaner for dishwashers.
FYI
