How to Clean a Moldy Dishwasher: Say Goodbye to That Funky Smell

Ever opened your dishwasher and caught a whiff of something… less than fresh? Yep, that’s mold, sneaking in and making your kitchen appliance smell like a science experiment gone wrong. Gross, right?

But don’t worry, you’re not alone—and better yet, cleaning it isn’t rocket science. Imagine this: a sparkling clean dishwasher that smells fresh and actually helps your dishes come out spotless, every single time.

So, how do you kick mold out for good? Let’s dive into it.


Why Does Mold Even Grow in Dishwashers?

You might be wondering, “Isn’t a dishwasher supposed to be hot and steamy? How does mold survive that?” Well, here’s the deal: dishwashers go through wet and warm cycles—perfect conditions for mold spores to thrive, especially in those hidden nooks and crannies.

Mold loves hanging out in places like the rubber gasket around the door, drain areas, and the filter. If you’re skipping regular cleanings, mold can build up faster than you think.


Step 1: Clear Out and Inspect Your Dishwasher

Before you grab your cleaning supplies, start by emptying your dishwasher completely. No sneaky plates or utensils hiding in there!

Next, give the interior a good look. Check the door gasket (that rubbery seal around the door)—mold loves to hide there. Peek under the bottom rack and around the filter too. If you see any black or greenish spots, it’s time to get scrubbing.


Step 2: Give It a Good Scrub

Grab a soft brush or old toothbrush and some warm, soapy water. Focus on those moldy spots—especially the gasket and around the drain area. If you want a natural cleaner, mix equal parts water and white vinegar. Vinegar is like the superhero of mold fighters.

Don’t forget to remove and clean the dishwasher filter if your model allows it. Filters can collect gunk that becomes a mold playground.


Step 3: Run a Cleaning Cycle with Vinegar or Dishwasher Cleaner

Now for the magic trick: run a cleaning cycle.

Here’s a little pro tip: place a cup of white vinegar in a dishwasher-safe container on the top rack and run a hot water cycle. The vinegar will help dissolve grease and kill mold lurking in hard-to-reach spots.

Alternatively, you can grab a dishwasher cleaning tablet or powder specifically designed to tackle odors and buildup—these work wonders too.


Step 4: Baking Soda to the Rescue

After the vinegar cycle, sprinkle a cup of baking soda across the bottom of the dishwasher and run a short, hot cycle. Baking soda freshens things up and helps remove any lingering stains.


Step 5: Keep Mold at Bay with Regular Maintenance

No one wants to repeat this mold-fighting saga often, right? So here’s how to keep your dishwasher smelling fresh and mold-free:

  • Wipe down the door gasket and interior edges regularly with a vinegar-water mix.
  • Leave the dishwasher door slightly ajar between uses to help it dry out.
  • Run a vinegar cleaning cycle once a month.
  • Check and clean the filter routinely.

Why Bother?

You might be thinking, “Is this really worth all the fuss?” Absolutely! A moldy dishwasher not only smells bad but can affect your dishes’ cleanliness—and possibly your health. Plus, keeping your dishwasher clean helps it run better and last longer. Win-win!


So, next time your dishwasher throws a little moldy tantrum, you’ll be ready to tackle it head-on. Imagine opening that door to a fresh, clean, and happy dishwasher every time!
