How to Fix a Dishwasher That Leaves White Scum

Dishwashers typically get the job done when it comes to keeping dishes clean, but they can sometimes leave behind a white scum on your dishes. This film is especially noticeable on clear items like glassware and glass plates or baking dishes. The scum accumulates as a result of high mineral content in your water supply. By adding an additional cleaning element to the wash cycle, you can quickly break up the minerals before they settle onto the dishes. This not only removes the white scum, but also prevents it from coming back in the future.
