Most of us think of the dishwasher as a magical box that just takes care of itself. You load it up, press a button, and boom—sparkling clean dishes. But here’s the catch: even the hardest-working appliance in your kitchen needs a little TLC. And in this case, that means thorough dishwasher cleaning.

If your dishes are coming out a little cloudy, smell a little off, or just aren’t looking as fresh as they used to, your dishwasher might be trying to tell you something. At AAA Appliance Service Center, our home appliance repair team has seen firsthand how small cleaning oversights can lead to big issues. So, before you blame your detergent or rinse aid, explore these five sneaky spots you’re probably forgetting to clean.

1. The Filter

Where it is: At the bottom of your dishwasher, under the bottom rack.

We get it—“dishwasher filter” sounds like something only a plumber needs to know about. But this little guy is a food trap, catching all the bits and crumbs left behind after dinner. And if it’s not cleaned regularly, let’s just say it gets pretty gross.

How to clean it: Ensure you have an empty dishwasher, then twist it out (check your manual if you’re not sure how), rinse it under warm water, and use an old toothbrush to scrub off any stuck-on gunk. Do this once a month, and you’ll be amazed how much fresher your dishwasher smells.

2. The Spray Arms

Where they are: Spinning around under your racks.

Those little holes in the spray arms? They’re what blasts water onto your dishes. Over time, they can get clogged with mineral deposits or food particles, especially if you’ve got hard water.

How to clean them: Take the arms off (usually they just snap out), soak them in warm vinegar, and poke the holes clean with a toothpick or skewer.

3. The Door Seal (That Rubber Gasket You Never Notice)

Where it is: Around the edge of your dishwasher door.

It’s easy to overlook, but that rubber seal is a sneaky little hiding place for gunk, grease, and even mold. And since it stays damp most of the time, making it an ideal spot for bacteria to live.

How to clean it: Wipe it down with a damp cloth and a little vinegar or mild soap. And be sure to get into those folds for a deep clean! You’ll probably be grossed out by what’s been lurking there—don’t say we didn’t warn you.

4. The Utensil Basket

Where it is: Usually on the bottom rack, or sometimes mounted on the door.

That plastic basket holding your forks and spoons might look clean, but it’s a sneaky grime collector. Food particles often get trapped in the slats and corners, and after a while, they can get funky.

How to clean it: Pop it out, soak it in warm, soapy water, and give it a good scrub with a brush. Let it air dry before you pop it back in.

5. The Drain Area

Where it is: Under the filter, at the very bottom. Out of sight, out of mind—but this little spot is where all the junk ends up. From food bits to broken glass, we’ve found some interesting things in dirty dishwasher drains over the years.

How to clean it: Remove the bottom rack and take a peek. Use gloves and a paper towel to scoop out anything that shouldn’t be there. If it’s looking pretty gnarly or if water isn’t draining properly, it might be time to contact a reliable appliance repair service.

Bonus Tip: Give It a Spa Day

Once you’ve cleaned all the hidden spots, run your dishwasher empty on the hottest cycle with a bowl of distilled white vinegar and baking soda on the top rack (or a dishwasher cleaner if you prefer). It’ll help dissolve grease, kill odors, and leave everything smelling fresh.
