Ever open the dishwasher and find cloudy glasses or a weird smell creeping out? That usually means the machine that cleans everything else needs a little care of its own.
At Maid This, a leading site that connects households across the U.S. with trusted cleaning pros, we see this all the time and know a quick reset can change the game. This guide walks you through a simple plan, so your dishwasher runs smoother, smells fresher, and your dishes come out sparkling.
Why Clean Your Dishwasher?
A clean dishwasher helps your dishes come out cleaner, with fewer spots and less film. Food bits and soap residue can block water flow, so removing that gunk keeps spray arms working like they should.
Regular cleaning also stops funky odors from building up. That sour smell usually comes from trapped grease and food, and it sticks around if it is not cleared.
Taking care of the filter, seals, and spray arms stretches the life of the appliance. Parts that stay clear of buildup face less strain, so the machine runs better for longer.
What You’ll Need
Gather your supplies before you start, so you can move through the steps without stops and starts.
- Rubber gloves
- Paper towels or clean rags
- Soapy water
- White vinegar
- Baking soda
- Old toothbrush or small cleaning brush
- Dishwasher-safe bowl
- Toothpicks, optional
- Olive oil, for stainless steel exteriors
- Microfiber cloth, for stainless steel exteriors
Most of these items sit in the pantry or cleaning caddy already, which makes the job fast and budget friendly.
Step-by-Step Dishwasher Cleaning Guide
The whole process is simple and does not take a ton of time. We break it into small chunks, so you can tackle one part, grab a sip of coffee, then finish up without stress.
Step 1: Wipe Down the Interior
Slide out the bottom rack and lift out the utensil basket, then set them in the sink. Mix warm soapy water in a bowl or bucket, nothing fancy needed.
Use a damp cloth or paper towel to wipe the door, edges, rubber seams, and hinges. Work into the crevices where grime hides, and give the float and soap dispenser a careful wipe.
If you see moldy spots, scrub with the toothbrush and soapy water until they lift. Rinse your cloth and go over the area again to pick up any loosened residue.
Once the interior looks clean, let us move on to the parts that actually catch debris and can slow water flow.
Step 2: Clean the Filter
Most filters twist out from the bottom of the tub. If you are unsure, check your manual or a quick model search for a diagram.
Rinse off the big food bits under warm water. If the filter looks grimy, soak it in soapy water for about 30 minutes, then scrub with the toothbrush to clear the mesh.
Rinse well and let it air dry while you wipe the filter housing. Use a toothpick to gently clear any clogged spray arm holes, then give the spray arms a quick rinse if they are removable.
| Trouble Spot | What to Use | How Often | Quick Tip |
| Filter and housing | Soapy water, toothbrush | Monthly | Twist gently to avoid cracking tabs. |
| Spray arm holes | Toothpicks, warm water | Every 2 to 3 months | Spin arms by hand to spot blockages. |
| Rubber door gasket | Soapy rag, vinegar on stains | Monthly | Wipe the groove that traps crumbs. |
| Interior tub | Vinegar cycle, baking soda | Quarterly | Run hot water at the sink first for a hotter start. |
| Exterior panel | Vinegar, microfiber, olive oil for SS | Weekly touchups | Wipe with the grain on stainless steel. |
With debris out of the way, you are ready to freshen the interior and clear any lingering film.
Step 3: Sanitize with Vinegar
Slide the bottom rack and utensil holder back in place. Fill a dishwasher-safe bowl with 2 cups of white vinegar and set it on the top rack.
Run a hot cycle without detergent. The vinegar breaks down soap film and mineral deposits, leaving the tub cleaner and less likely to smell.
That takes care of buildup. Next up, we will target stubborn odors so the machine smells fresh.
Step 4: Deodorize with Baking Soda
Sprinkle one cup of baking soda on the bottom of the tub. Close the door and let it sit overnight to absorb lingering smells.
In the morning, run a short, hot cycle. Your dishwasher should smell clean, not perfumy, which is what we want.
With the inside fresh, a quick shine on the outside will finish the job and make the whole kitchen look tidy.
Step 5: Clean the Exterior
For stainless steel, mist vinegar onto a microfiber cloth and wipe with the grain. Add a small dab of olive oil to a clean cloth, then buff gently to a soft sheen.
For plastic fronts, use a sponge with soapy water, then dry with a microfiber cloth. Do the control panel last with a barely damp cloth to avoid moisture getting into buttons or a display.
Maintaining Your Clean Dishwasher
Now that it is spotless, small habits will keep it that way and save you time later. A tidy machine works better and needs fewer big cleanups.
- Give plates a quick rinse or scrape to cut down on food buildup.
- Clean the filter monthly to keep water flow strong.
- Run a vinegar cycle every few months to stop odors and film.
If you like a simple schedule, the outline below keeps things on track without overthinking it.
- Weekly, wipe the door edges and gasket with a damp cloth.
- Monthly, clean the filter and check spray arm holes.
- Quarterly, run vinegar followed by baking soda as shown above.
One last hint, run hot water at the sink right before starting a wash. That helps the dishwasher begin with heated water, which lifts grease more easily.
