Our dishwashers have a demanding job: We give it a load of dirty dishes, and we expect it to clean them all, without fail, all week long. Unfortunately, not many people remember to give the dishwasher some TLC until a problem becomes obvious. Dishwasher maintenance cleaning is key. Hints that your dishwasher is in need of preventative maintenance include unpleasant odors, standing water from not draining completely, build-up of grime, and dishes that are not properly washed. If you’re looking for a dishwasher maintenance DIY guide, or are wondering, “How often should I clean my dishwasher?”, follow along once a month, every month.
Dishwasher Maintenance DIY
Are you wondering, “How often should I clean my dishwasher?” Dishwasher maintenance cleaning needs to be done once a month, every month. Grab your favorite pair of rubber gloves and follow along to keep your dishwasher smelling and cleaning great all year long.
First, Clean Dishwasher with Vinegar and Baking Soda
Before proceeding, make sure your dishwasher is completely empty. To clean dishwasher with vinegar and baking soda, you’ll need to gather the following items:
- A small, dishwasher-safe bowl
- Two cups of white vinegar
- 1 cup of baking soda
Pour two cups of white vinegar into the dishwasher-safe bowl. Place the bowl of vinegar on the top rack of your dishwasher and run a complete wash cycle, preferably with the hottest water temperature available. Once the first wash cycle is complete, open your dishwasher and ensure that all of the vinegar has been removed from the bowl. Make sure that the dishwasher tub has drained completely.
Next, sprinkle one cup of baking soda into the bottom of the dishwasher. Run another cycle on hot, also without dishes. Make sure to clean the dishwasher with vinegar and baking soda to properly descale.
A dishwasher that smells typically has a hidden source of the stench, so you’ll want to inspect the washer tub and the door seal thoroughly. If there is any mold or mildew that has built up, you’ll definitely want to remove it. This can easily be accomplished with a swipe of a dishcloth dipped in vinegar. For particularly tough build-ups, use a basic kitchen cleaner with a small brush to scrub away the build-up.
