It might seem counterintuitive, but even your dishwasher needs a good cleaning now and then. Over time, grime can build up, affecting how well it cleans your dishes and sometimes causing an unpleasant “wet dog” odor. Regular maintenance not only keeps your dishwasher running smoothly but also ensures your dishes are washed properly and stay hygienic.
The best part? Cleaning your dishwasher is straightforward and doesn’t take much effort. Here’s a guide to keeping it fresh, efficient and odor-free, along with tips on how often you should do it.

How to clean a dishwasher
Step 1: Clean the dishwasher filter
The filter is the place where food particles get caught. A stopped-up filter can cause overflows, so it’s important to give it a cleanup every week or so. It can be found on the floor of the inside of the dishwasher. Simply unscrew the knob and lift the filter out (the location and removal will vary depending on the brand, so check your owner’s manual).
Wash the filter by rinsing it with warm water and dishwashing soap, then give it a good scrub with an old toothbrush. Rinse with clean water and let the filter air dry before popping it back into place.
Step 2: Clean the dishwasher seal
The seal is what keeps the water inside your dishwasher and not on your floor. To keep it clean, once a month scrub the seal with warm water and wipe it down with a clean, dry cloth.
Step 3: Declog the water sprayers
The spraying arms in your dishwasher need a little love every six months or so. Use a toothpick to pry any food particles from the sprayer holes. This will increase the amount of water that comes out, increasing cleaning power.
Step 4: Get the gunk out of the silverware basket
The silverware basket can become unsanitary pretty quickly. Once a week, remove it and wash it with warm water, a bottle brush and dish soap. Be sure to get out any food particles that may be stuck inside the cups to prevent mold.

What to do if your dishwasher smells
If your dishwasher is starting to smell a little rank, there is an easy way to deodorize it. Some people say to put one cup of white vinegar into the bottom of your empty dishwasher and run the deep cleaning cycle — however, vinegar can damage the plastic in your dishwasher, so you might want to try this method instead. Sprinkle baking soda on the bottom of the washer, let it sit overnight, and then run a normal load while the dishwasher is empty. That should get rid of that gross wet dog smell.
How often should you clean your dishwasher?
Experts recommend giving your dishwasher a deep clean once a month to keep it running efficiently and smelling fresh. If that feels like too much work, aim for at least once every three months. Start by removing and rinsing the filter to clear out food debris, then run an empty cycle with a dishwasher-safe cleaner or baking soda. This simple routine can prevent grime buildup, improve performance and keep those funky odors at bay.
One more tip: Remove rust from the latch
After a few years of diligent use, your dishwasher door latch may start to get a little rusty. To fix this, rub it down with stainless steel cleanser and steel wool. Rinse the latch and buff it dry with a cotton cloth. To finish, coat it with clear fingernail polish to waterproof the metal and prevent further rust growth.
