Commercial dishwashers work well in restaurants and similar facilities that constantly have a large number of dirty dishes requiring cleaning. Limescale buildup is a common problem with any appliance that uses water. The lime content in your water supply settles onto the surface of the dishwasher, leaving you with a slimy and discolored buildup. De-lime the dishwasher safely with a chemical-free cleaning ingredient that breaks through the lime.
Saturate a nylon scouring pad with white vinegar and scrub as much of the scale as possible.
Pour your regular amount of dishwasher detergent into the unit.
Pour 1 quart white vinegar into a dishwasher-safe bowl and place on an empty rack of the dishwasher.
Turn on the dishwasher and let the wash cycle complete. The vinegar will break up and dissolve any leftover scale.
Clean the dishwasher with the vinegar routine one to two times per month, depending on the amount of scale that builds up.
