Pour 2 cups of white vinegar in a dishwasher-safe bowl and place the bowl on the bottom rack of your empty dishwasher. Select a dishwasher cycle with an air-dry or energy-saving dry option and press start. During the cycle, the vinegar will mix with the wash water to help neutralize odors and clean your dishwasher.
Over time, soap scum and grime can accumulate on the walls and door of the dishwasher. Simply scrubbing them down with hot soapy water and a cloth or scrub brush can make a huge difference. While you're at it, wipe down the racks and door gaskets, which can also accumulate mold and mildew.
Alternatively, you can sprinkle ½ cup of baking soda all over the floor of the inside of your dishwasher, and run it (empty) on a quick, hot cycle. Skip the vinegar entirely. Baking soda has similar properties to vinegar and should also get the job done.
If yours has developed an unpleasant odor, start by cleaning the drain trap and clearing any clogs from the spray arms with a toothpick. Then run the dishwasher according to our directions, first with vinegar to cut through grease and soap scum, then with baking soda to neutralize smells.
Use Citric Acid in the Automatic Dispenser
Add one tablespoon spoon of citric acid powder to one-fourth cup of boiling water. Stir well until all of the powder is dissolved. Add the mixture to the automatic rinse aid dispenser and run the dishwasher cycles as usual.
The most common cause of dishwasher odor is a dirty filter. Food particles get trapped in your dishwasher's filter, and without regular cleaning, your filter can start smelling foul. Clogged filters can also recirculate dirty water, causing your dishwasher to not clean properly.
The baking soda will remove stains and freshen the dishwasher. The result? A bright, sparkling dishwasher that smells oh-so-clean.
Sprinkle 1 cup of baking soda along the bottom of your dishwasher and rinse on a hot-water cycle. Repeat this process when you have especially stubborn stains or smells.
Mix ¼ cup of baking soda with ¼ cup of water and add it to your machine's detergent container. Use four cups of plain white (not apple cider) vinegar to a top-load machine or two cups to a front-load model. Pour the vinegar into the drum. Run a high-temperature cycle.
Pour 1 cup of bleach into a dishwasher-safe, bleach-safe bowl and place it on the top rack of your dishwasher. Then run a full cycle, but skip the drying cycle. Tip: Do not use bleach in a stainless steel dishwasher or a dishwasher that contains stainless steel parts, as bleach will damage it.
If you opt to take the DIY route to fight residue and buildup, go with vinegar in an empty dishwasher. To clean your dishwasher with vinegar, place a dishwasher-safe bowl filled with one cup of distilled white vinegar on the top rack and run a pots-and-pans or heavy (hot) cycle without detergent or dishes.
Baking soda and baking powder are not chemically the same, and so you should not substitute baking soda for baking powder when following a cleaning guide. Whilst baking powder may offer some cleaning effect, it really is just designed for baking, and so it is not recommended that you use it for any cleaning purposes.
Soda crystals are used to descale and clean a washing machine and get rid of stains on laundry, which leads people to assume these cleaning crystals are suitable for the dishwasher too. However, according to the experts at Dri-Pak, you should never put soda crystals in the dishwasher.
Baking Soda + Vinegar
"Baking soda is basic and vinegar is acidic," says Bock. "When you put them together you get mostly water and sodium acetate. But really, just mostly water." Plus, vinegar causes baking soda to foam up. If stored in a closed container, the mixture can explode.
Clean the Drain Filter and Drain
You can also pour a solution of one tablespoon of baking soda and two tablespoons of vinegar down the dishwasher drain while your at it. Let it sit for 15-20 minutes. Then, run a rinse cycle. This will help clear out the drain pipe, reducing odors.
Filter clogs and hose backups are the two most common causes of dishwashers that smell like rotten eggs. Make sure your dishwasher is draining correctly and clean out the filter and drainage hose if it's not.
It's highly likely that the odor is due to mildly contaminated water within your dishwasher which, as the lingering bacteria dries, activates a strange, faint “wet dog” odor. This can be caused by leftovers remaining in the machine, or just stagnant recycled water that's been leftover!
After you fill the jar with white vinegar, add 4-5 drops of lemon essential oil. If you don't have lemon essential oil on hand, you can use the juice from a 1 lemon. This may result in a cloudy mixture, but it will serve the same purpose. And, that's it!!
Make Dishwasher Detergent Tablets
Add one cup of washing soda, one cup of borax, one-half cup of Kosher salt, and three-fourths cup of lemon juice to a mixing bowl. Stir well with a wooden spoon to mix. Place one tablespoon of the mixture into small silicone molds or ice cube tray sections.
Clean your dishwasher monthly to prevent a buildup of germs and maintain the efficiency of the machine — you want to make sure your dishes are clean!
