The unsavory fluid, mostly water, left in upturned glassware, measuring cups and the crevasses of other items found in a dishwasher after full completion of a wash cycle. This fluid contains sediment, particles and other dissolved elements freed from these items during cleansing. On occasion these elements, though visible, cannot be linked to any food substance known to have been present at the time of the machine's loading.
GROSS! Everything in the machine turned upside down. Now I've got to dump all this nasty "dishwasher chum." out and rerun it all!
