Best Way to Clean Your Dishwasher 

A sparkling clean dishwasher full of dishes

If your dishwasher isn't clean, how can you expect it to clean your dishes? Here are some pro tips on how to clean your dishwasher.

Doesn’t a dishwasher clean itself? Unfortunately, not really. While it feels like the hot water and dish soap that slosh around inside your dishwasher every day should keep the unit clean, the food particles and residue on your dirty dishes get in the way— a lot of that gunk remains in the dishwasher after the cycle. Plus, detergent can form a soap film on the inside of your dishwasher.

How often should I clean my dishwasher?

You typically only need to clean your dishwasher about once per month, but you may need to do it more often if it’s getting particularly dirty. 

Luckily, cleaning your dishwasher doesn’t have to be an overly time-consuming process if you know the right steps. 

6 steps for a squeaky clean dishwasher

A sparkling clean dishwasher means sparkling clean dishes, so it’s worth the effort. Grab some white vinegar, baking soda, a soft cloth, and an old scrub brush, and let’s get to work. These six easy diy dishwasher cleaning solutions will have your dishwasher looking (and working) like new in no time.

Follow these steps for a squeaky clean dishwasher:

1. Check the Drain

You’d be surprised what can get caught in the dishwasher drain: bones, crab shells, a Barbie doll head— the sky’s the limit. Service professionals find all kinds of things down there. 

As a first step in dishwasher cleaning, check out the drain and remove any debris, food chunks, or other fun stuff that’s hiding down there.

2. Clean the Filter

Next, pull out the screen and filter, and clean both thoroughly with soap and hot water. If you want to keep your dishwasher cleaner in general, yank out the bottom rack, and remove any food pieces or other residue from the screen and filter each time you wash a load of dishes. Once you’ve cleaned the screen and filter, you can replace them.

3. Deep Clean the Sprayer Arms

The little holes in your dishwasher’s sprayer arms can get clogged with food residue easily, and this can make the dishwasher less effective. Remove the sprayer arms and use a piece of wire or a toothpick to unclog the holes.

4. Run a Wash Cycle with Vinegar

Now it’s time to get down to business— how to clean a dishwasher with vinegar. Put two cups of cleaning vinegar (it’s a little stronger than the eating kind, but if you don’t have any cleaning vinegar, the eating kind will do) in a dishwasher-safe bowl or cup on the top rack of the dishwasher. Run a hot water cycle with nothing else in the dishwasher but that cup or bowl of vinegar. The vinegar will disinfect and deodorize the dishwasher, while also cutting through grease and grime.

5. Run a Second Wash Cycle with Baking Soda

To further deodorize and clean your dishwasher, sprinkle a cup of baking soda on the bottom of the unit and run another hot water cycle— this can be a short cycle, if you want. You can also choose to clean your dishwasher with a commercial dishwasher cleaning tablet, but make sure you follow the instructions on the box. Some of them can be added to a regular dishwasher cycle, but others should be used in an empty machine.

6. Clean the Door Seal and Controls

Finally, check out your dishwasher’s door seal, especially if it’s been leaking onto the floor lately. That will happen when the door seal is damaged or worn, but it can also occur when the seal is merely dirty. Clean any debris or food residue from the door seal and while you’re at it, wipe off the dishwasher controls, too. 

Tips to keep your dishwasher clean longer

Maintaining a clean dishwasher is all about simple habits that prevent buildup and keep things running smoothly. Here are some tips to extend that fresh-clean feeling:

  • Give your dishes a quick rinse to remove large food particles before loading them into the dishwasher. This helps prevent clogging and keeps the interior cleaner.
  • Run the hot water in your sink before starting the dishwasher. This makes sure that the dishwasher starts with hot water, which helps dissolve grease and food residue more effectively.
  • After unloading, leave the dishwasher door slightly ajar to allow the interior to dry completely. This helps prevent mold and mildew growthh, and helps you avoid a smelly dishwasher.
