Dishwashers Need Cleaning Too!
Most dishes go in dripping at least some sauce or other food-related liquid as it's not necessary to pre-rinse dishes before loading them.
While most may assume that dishwashers are self-cleaning, they do require some care to maintain peak function. This is because the warm, moist environment and alkaline pH values inherent in the machines make them prime breeding grounds for some pretty nasty fungi and bacteria.
A small study published in the Journal of Fungal Biology found that 62 percent of dishwashers tested contained fungi that can be problematic for humans. Yet another paper, published in Applied and Environmental Microbiology, found significant bacteria and fungi in dishwashers, which they describe as "diverse habitats for microorganisms to adapt and flourish." Fortunately, maintaining a clean dishwasher is quick and easy with the steps below.
Wipe down surfaces
Most dishes go in dripping at least some sauce or other food-related liquid as it's not necessary to pre-rinse dishes before loading them. However, the foodstuffs on dishes can build up over time and leave residue in the dishwasher. To fix it, use a damp cloth with minimal liquid dish detergent to wipe down the rubber seals and the door interior. This will keep grime and other nastiness from building up.
Additionally, every dishwasher comes equipped with a spray arm, which should be removed and wiped down with a damp towel every six months. The owner's manual contains easy instructions on model-specific steps, but a standard recommendation is to dislodge any clogs in the spray holes using a toothpick.
Clean the filter
Many people are unaware that their dishwasher even has a filter, so don’t fret if it has been neglected. Typically located at the bottom center of the dishwasher, the two-part device serves a couple of purposes. The upper filter is designed to keep chunks of food and other foreign particles from reaching the pump, while the lower filter prevents food bits from returning to the clean dishes.
Indications that the filters need cleaning include any residual food on the upper filter or dishes that keep coming out dirty, despite running through a complete cycle. The frequency of cleaning depends on frequency of use, and whether or not dishes are rinsed before placing them in the machine.
To remove the filter, check the owner’s manual for removal steps. Then, rinse under running water until all residue is cleared off. Reinstall according to manufacturer directions.
Run a cleaning cycle
Mineral deposits can build up over time due to hard water, so many manufacturers recommend running a dishwasher-specific cleaning solution every month or so. Some homeowners opt to use commercially available dishwasher cleaners, but 2 cups of white vinegar can also be effective to tackle hard water deposits and soap scum. Be sure to run a cleaning cycle with an empty machine, using the highest heat and heaviest setting available.
Assess rack coating
Over time, the protective coating on racks may wear away and chip. Inspect frequently for wear or chipping. If coating begins to flake off, repair solutions can be found at hardware stores like Home Depot or Lowes.
Clean out soap dispenser
An old toothbrush can effectively clean plastic compartments that accumulate debris or soap scum.
