Many people think their dishwashers are not prone to bacteria. Why would they be? The environment utilizes strong dishwasher detergent and hot water. The misconception is that it can be one of the least likely places to find anything.
The U.K. Daily Mail reports that researchers found 62 per cent of dishwashers contained the fungi Exophiala dermatitidis and E. phaeomuriformis on the rubber band in the door. Both of the black yeasts are known to be dangerous to human health. Both bacterias displayed stronger than normal resistances to heat (hot water), active corrosives, detergents, and both acid and alkaline water. This sudden education on the characteristics of certain bacteria was surprising as these are a series of resistances not previously observed. One of the bacterias (Exophiala dermatitidis) is known as an agent of human disease and can affect the lining of lungs of patients with cystic fibrosis.

Many people will run white vinegar through their dishwashers once a month. We recommend this practice, and even increasing the number of times you do this to twice.
