How to Clean Your Dishwasher the Right Way: Step-by-Step Guide
Removing grime and odors helps this appliance run smoothly and maintain peak performance.
How to Clean Your Dishwasher the Right Way
Discovering food residue, hard water stains, or odd smells in your dishwasher is more common than you might think. Your dishwasher tackles the toughest grime meal after meal, so it’s only fair to return the favor with routine cleaning. With the right schedule and methods, you can easily maintain both hygiene and efficiency. This guide breaks down everything you need to know to get—and keep—your dishwasher sparkling clean, including step-by-step instructions for vinegar, baking soda, and bleach methods, plus essential maintenance for optimal performance.
Why Is Cleaning Your Dishwasher Important?
At first glance, a dishwasher cleans itself every cycle. However, over time, food particles, soap scum, hard water minerals, and grease build up, clogging sprayer arms, tainting dishes, and causing unpleasant odors. Regular cleaning ensures your appliance works at top efficiency and extends its lifespan by:
- Preventing mold, mildew, and bacteria growth.
- Eliminating bad odors caused by food debris and stagnant water.
- Maintaining optimal washing and drying performance.
- Reducing wear and tear on key components like filters and spray arms.
How Often Do You Need to Clean Your Dishwasher?
You don’t need to obsessively scrub your dishwasher every weekend. Most experts recommend two key routines—one weekly and one monthly:
- Weekly: Wipe down the control panel, door edges, and seals where grime collects. Check for any food trapping in crevices.
- Monthly: Complete a deep clean, including a drain trap scrub and using an alkaline or acidic wash to break down mineral deposits and grease.
Don’t wait for problems. If you notice mold, mildew, a musty or rotten smell, or underperforming washes (like cloudy glasses), it’s time to clean immediately.
Common Signs Your Dishwasher Needs Cleaning
- Unpleasant smells when you open the door.
- Visible gunk or food particles at the bottom or around the filter.
- Cloudy or spotted glassware after a cycle.
- Reduced water drainage or standing water after a cycle.
- Presence of black or pink slime along the seals.
Cleaning Solutions: What Should You Use?
You don’t need fancy powders or expensive tablets. The best dishwasher cleaning solutions are white vinegar, baking soda, and (for specific circumstances) bleach. Each addresses a different challenge:
| Cleaning Agent | Purpose | Precautions |
|---|---|---|
| White Vinegar | Dissolves hard water buildup, deodorizes | Safe for all interiors |
| Baking Soda | Eliminates stains, freshens, removes residue | Safe and gentle on all materials |
| Bleach | Mold, mildew, and germ elimination | Never use with stainless steel interiors or with vinegar |
Step-By-Step: How to Deep Clean Your Dishwasher
Deep cleaning your dishwasher consists of several straightforward tasks. Here’s how to tackle it like a pro:
1. Inspect and Clean the Drain Trap
The drain trap (or filter) collects food particles. If it’s clogged, your dishwasher can develop odors and drainage woes.
- Remove the bottom rack to access the drain trap (usually a round or rectangular component in the tub floor).
- Twist and lift out the filter or cover as per your user manual.
- Rinse the filter under hot water, using a soft brush to dislodge stuck particles. Soak in a solution of warm water and dish soap for stubborn grime.
- Wipe around the filter compartment before reinstalling.
2. Wash Removable Parts and Racks
- Take out utensil holders and racks if possible.
- Soak in warm, soapy water for 10–15 minutes.
- Scrub with a sponge or brush, focusing on corners and attachment points.
- Rinse thoroughly and allow to air dry before returning them to the dishwasher.

3. Clean Spray Arms
- Check for food particles clogging spray arm holes.
- Remove the spray arms if your model allows (refer to your manual).
- Use a toothpick or fine wire to clear debris from holes.
- Rinse under warm water and reinstall.
4. Wipe Down Door, Gasket, and Exterior
- Use a soft cloth dampened with warm, soapy water or white vinegar to clean the door’s edges and the rubber seal.
- For heavy buildup, use a soft brush. Don’t forget the control panel and handle.
- Dry with a soft towel.
5. Deodorize and Remove Buildup With Vinegar
- Place a dishwasher-safe cup or small bowl upright on the upper rack. Fill with white vinegar (1–2 cups).
- Run the dishwasher empty on the hottest setting.
- The vinegar dissolves mineral deposits, residual soap, and odors. For ongoing sparkle, mist the tub with white vinegar between cycles.
6. Eliminate Stubborn Odors and Residue With Baking Soda
- After the vinegar cycle, sprinkle 1 cup of baking soda evenly over the bottom of the empty tub.
- Run a short, hot cycle (no detergent or dishes).
- Baking soda acts as a mild abrasive and neutralizes persistent odors and discoloration.
7. Optional: Disinfect With Bleach (Plastic Interiors Only)
- Only use bleach if your dishwasher has a plastic interior and you’re certain there are no stainless steel components, as bleach corrodes metal.
- Place a bowl filled with 1/2 cup bleach on the top rack. Run a full, empty dishwasher cycle on the hottest setting.
- Never mix bleach and vinegar, as this releases toxic chlorine gas.
Helpful Maintenance Tips
- Scrape (not rinse) dishes before loading to remove chunks of food, but leave a little residue. Modern dishwashers are designed to sense food on dishes and adjust the wash cycle; rinsing dishes can trick sensors into running shorter, less effective cycles.
- Occasionally check and clear the drain or filter to prevent clogs.
- Inspect and wipe down seals to prevent mold and mildew.
- Leave the door slightly open after a cycle to let the interior dry and minimize odor buildup.
- Use dishwasher-safe cleaners or a vinegar rinse once a month for ongoing freshness.
- Maintain softener salt levels in hard water areas (if your model has this feature).

Common Questions About Dishwasher Cleaning
How often should I clean my dishwasher?
Wipe surfaces and seals weekly, and do a deep clean—including the filter and an alkaline or acidic wash—monthly. If you notice mold, odors, or decreased efficiency, clean right away.
Can I use regular dish soap to clean my dishwasher?
No. Dish soap produces suds that can overflow and damage your appliance. Stick to vinegar, baking soda, or cleaners formulated for dishwashers.
Can I clean my dishwasher with vinegar?
Yes. Place a cup of white vinegar on the upper rack and run a hot empty cycle. This removes mineral buildup, grease, and odors.
Is baking soda safe for dishwasher cleaning?
Absolutely. Sprinkle about a cup on the bottom of the tub and run a short, hot cycle. It freshens, scrubs, and neutralizes persistent odors safely.
Is it safe to clean my dishwasher with bleach?
Use bleach only if your interior and parts are all plastic. Bleach will corrode stainless steel. Never use bleach with vinegar simultaneously.
How do I clean the drain trap or filter?
Remove (twist and lift) the filter at the bottom, scrub it under hot, soapy water, and remove trapped food with a soft brush. Clean the compartment before replacing the filter.
How do I keep my dishwasher smelling fresh between deep cleans?
Mist the tub and seals with vinegar between uses, and leave the door ajar after each cycle to let the interior dry.
Frequently Asked Questions (FAQs)
Q: Why does my dishwasher smell even after running a cycle?
A: Persistent smells usually result from food trapped in the filter, seals, or drain. Cleaning the filter, using vinegar, and wiping the gasket should resolve odor problems.
Q: What natural alternatives remove dishwasher odors?
A: White vinegar and baking soda are the top choices—both are highly effective and safe for the dishwasher’s components.
Q: Can I use commercial dishwasher cleaner instead of vinegar or baking soda?
A: Yes, but household staples like vinegar and baking soda offer equivalent cleaning power at a lower cost and without harsh chemicals.
Q: Should I rinse dishes before loading the dishwasher?
A: No need to pre-rinse completely—scrape large debris only. Modern dishwashers use sensors that optimize cleaning when some food residue is present.
Q: Can a dirty dishwasher damage my dishes?
A: Yes, thick buildup can redeposit grime and leave glasses cloudy. Regular cleaning ensures dishes come out sparkling every time.
Conclusion: Keep Your Dishwasher Sparkling
Regular cleaning is straightforward with vinegar, baking soda, and occasional bleach (for plastic interiors). Not only does it prevent odors and unsightly buildup, but it also extends the lifespan of your machine and ensures your dishes always come out pristine. Set a monthly reminder—your dishwasher and your kitchen will thank you.
