Keeping a dishwasher spotless isn’t just about looks; it’s about performance.
Over time, grease, soap scum, and food particles build up inside, leaving behind odors and dull results.
I’ve learned that even the best dishwasher needs a proper clean every so often to work like new.
Using a dishwasher cleaner makes the job easy and quick: no scrubbing, no dismantling, just a few smart steps.
This method not only restores shine but also helps your dishes come out cleaner, your appliance lasts longer, and your kitchen smells fresher.
How Often Should You Clean Your Dishwasher
A clean dishwasher isn’t just about appearance. It’s about performance and longevity.
Regular cleaning prevents buildup that can affect how well it washes and drains. I like following a simple schedule that keeps everything running smoothly without much effort.
Daily upkeep removes debris before it hardens, while monthly deep cleans handle soap scum and mineral deposits.
For those with hard water, cleaning more often prevents cloudy residue and limescale.
With a little consistency, your dishwasher will always run efficiently, smell fresh, and stay sparkling clean.
How to Deep Clean a Dishwasher Step-by-Step
This step-by-step guide walks through removing and soaking parts, cleaning hidden edges, and running a targeted cleaning cycle.
Materials Required
| Item | Purpose |
|---|---|
| Warm water | For soaking removable parts |
| White vinegar (1 cup) | Cuts grease and removes odor |
| Dish soap | Breaks down grime and residue |
| DIY spray: 1 cup vinegar + 1 cup water + 1 tsp dish soap | For wiping edges and seals |
| Microfiber towels | For cleaning and drying |
| Soft brush or toothbrush | For scrubbing small areas |
| Flathead screwdriver | To remove vent covers |
| Stainless steel cleaner (optional) | For polishing exterior surfaces |
Step 1: Remove and Soak the Parts
Take out the bottom rack and twist the filter counterclockwise to lift it out.
Remove the bottom basket screen as well. Place these parts in a sink filled with warm water, white vinegar, and a small amount of dish soap to soak for several minutes.
Step 2: Rinse and Pre-Clean
Give the filter and screen a light rinse under running water to remove loose debris. Use a soft brush or toothbrush to gently scrub away buildup. Let them soak again briefly while working on the interior for a deeper clean.
Step 3: Clean Door Edges and Gasket
Spray the vinegar mix along the rubber door gasket, corners, and the inner lip that stays hidden when the door is closed. Wipe everything clean using a microfiber towel.
This helps remove grease, soap residue, and food particles that the wash cycle can’t reach.
Step 4: Check and Clean the Vent Cover
Locate the small vent cover and, if your dishwasher has one, use a flathead screwdriver to turn and remove it. Soak it in the same vinegar solution.
Wipe around the vent area to clear buildup, then rinse the cover and set it aside to dry.
Step 5: Rinse and Reassemble Soaked Parts
Drain the sink and rinse the filter, basket screen, and vent cover thoroughly. Remove all soap film and debris.
Once dry, place them back into the dishwasher to prepare for the cleaning cycle. Double-check that everything fits securely before continuing.
Step 6: Run the Dishwasher Cleaning Cycle
Run the kitchen tap for about 30 seconds to ensure hot water enters the machine. Add a dishwasher cleaner pod to the detergent cup or place a glass of white vinegar on the top rack. Select Normal Wash with High Temp and skip the heat-dry setting.
Step 7: Final Detail and Finishing Touches
Once the cycle ends, pull out the bottom rack and inspect the heating element and corners for residue or rust spots.
Wipe gently with the vinegar mix and a microfiber towel. Reinsert all parts, ensuring the filter locks in place, and finish by polishing the exterior for a clean shine.

How to Clean a Dirty Dishwasher with Dishwasher Cleaner
When my dishwasher starts to smell or look grimy, I like using a dishwasher cleaner to bring it back to life. It’s quick, effective, and doesn’t require scrubbing: just a few easy steps to make it look and smell fresh again.
Materials Needed:
- Dishwasher cleaning pod or liquid cleaner (like Finish or Cascade)
- Microfiber towel
- Warm water
Steps to Follow:
- Empty the dishwasher completely so the cleaner can reach every surface.
- Remove and rinse the filter under warm water to clear food and grease.
- Place the cleaner in the detergent slot or set it on the top rack as directed.
- Run a Normal or Heavy Wash cycle with High-Temp Wash on and Heat Dry off.
- Once it’s done, wipe the inside with a microfiber towel to remove loosened grime.
- Finally, leave the door slightly open for about an hour so it can air dry completely.
Pro Tip: Run hot water at the sink before starting the cycle. This ensures your dishwasher begins with the hottest water possible for a deeper clean.
Tips for Maintaining a Clean Dishwasher
Regular maintenance makes a big difference in how long your dishwasher lasts and how well it performs.
These simple habits take just a few minutes but keep your machine fresh, efficient, and odor-free between deep cleans.
- Wipe after each load: Remove leftover food or debris from the bottom after every wash.
- Deep clean monthly: Use a dishwasher cleaner or the baking soda and vinegar method.
- Clean the exterior: Wipe and polish the outside to prevent smudges and streaks.
- Inspect spray arms: Check for clogs to ensure proper water flow and cleaning power.
Clean after washing non-dishware items: This prevents cross-contamination and odors.
Keeping up with these small habits means fewer deep cleans and a fresher, more efficient dishwasher every day.
Conclusion
Cleaning my dishwasher regularly has made such a difference. It runs quieter, smells fresher, and actually gets my dishes cleaner.
It’s one of those simple habits that saves time and money in the long run. A few minutes each month keeps the buildup away and prevents costly repairs later.
Use either a cleaner pod, vinegar, or baking soda; the key is consistency. I like knowing my dishwasher is as clean as the dishes it washes.
