How to Clean Your Dishwasher the Right Way at Home?
Most people assume their dishwasher cleans itself since it runs soap and water all day. But that’s not quite true.
Over time, food particles, grease, and mineral deposits build up inside, causing foul odors and poor cleaning performance. A dirty dishwasher can actually make your dishes dirtier.
Here’s the brighter side: Learning how to clean your dishwasher is easier than most think, and it doesn’t require fancy products or hours of scrubbing.
This guide will lead you through simple, practical steps to clean every part of your dishwasher thoroughly. You’ll learn what to clean, which household items work best, and how often to do it for sparkling results.
Why Regular Dishwasher Cleaning Matters?
Your dishwasher faces a tough job every day. Food debris gets trapped in filters, spray arms, and door seals. Grease accumulates on the walls, and hard water leaves mineral deposits that clog the system.
This buildup doesn’t just create unpleasant smells; it actually reduces cleaning power and can damage the machine over time.
Regular cleaning keeps your dishwasher running efficiently and extends its lifespan. Experts recommend a deep clean once a month if you use it daily.
For lighter use, every two to three months works fine. But the filter should be rinsed weekly to prevent major clogs.
Signs you need to clean include white residue on dishes, a musty smell when you open the door, or poor washing results.
Don’t wait for these problems to appear, though. Staying ahead with routine maintenance saves money on repairs and replacement parts down the line.
How to Clean Your Dishwasher: Step-by-Step Process
Follow these straightforward steps to get your dishwasher spotless and running like new. You probably have most of the supplies at home already.
Step 1: Gather Your Cleaning Supplies
Before you start, collect white vinegar, baking soda, a soft brush or old toothbrush, and a microfiber cloth. You might also want dish soap and a small bowl.
These simple household items work just as well as expensive commercial cleaners. Having everything ready saves time and makes the process smooth.
Step 2: Remove and Clean the Filter
The filter sits at the bottom of your dishwasher and catches food particles. Twist or pull it out according to your model’s design.
Rinse it under warm running water and use a brush to scrub away stuck-on debris. This is the most crucial step because a clogged filter is the main reason dishwashers stop cleaning properly.
If the buildup is heavy, soak the filter in warm soapy water for 10 minutes before scrubbing.
Step 3: Clean the Spray Arms
Pull out the lower and upper spray arms, most twist off easily. Check the small holes for clogs and use a toothpick or thin wire to clear them. Rinse the arms under water and wipe them down.
Clogged spray arms can’t distribute water effectively, leaving dishes dirty.
Step 4: Scrub the Door, Gasket, and Edges
Food and grime collect around the rubber gasket and door edges where water doesn’t reach. Dip your cloth in warm, soapy water and wipe these areas thoroughly.
Pay attention to the corners and hinges. The gasket needs gentle care since harsh scrubbing can damage it. A clean gasket also prevents leaks and maintains a proper seal.
Step 5: Run a Vinegar Cleaning Cycle
Place a dishwasher-safe bowl filled with two cups of white vinegar on the top rack. Run a hot water cycle without any dishes inside.
The vinegar breaks down grease, removes mineral deposits, and kills bacteria. This cycle also freshens up the interior and gets rid of foul odors naturally.
Step 6: Follow With a Baking Soda Cycle
Sprinkle one cup of baking soda across the bottom of the empty dishwasher. Run a short hot water cycle. Baking soda is a gentle abrasive that removes stains and leaves everything smelling fresh.
It also neutralizes any remaining odors the vinegar might have missed. This two-step cleaning method is powerful yet safe for all dishwasher types.
Step 7: Wipe Down the Exterior
Don’t forget the outside. Use a damp cloth with a bit of dish soap to clean the front panel, handle, and control buttons. Stainless steel exteriors may need a special cleaner to avoid streaks.
A clean exterior makes your whole kitchen look better and prevents dust and grime from working their way inside.
How to Clean a Dishwasher with Hard Water Buildup?
Hard water leaves white, chalky deposits that regular cleaning won’t remove. If you have mineral buildup, add these extra steps to your routine:
- Pause the vinegar cycle halfway through and let it soak for 30 minutes before restarting
- Use citric acid for stubborn deposits. Sprinkle 3-4 tablespoons on the bottom, and run a hot cycle
- Soak the filter separately in a vinegar-water solution for 20 minutes if it has a mineral coating
- Increase cleaning frequency to every two weeks instead of monthly
- Consider installing a water softener system to stop buildup at the source
- Fill your rinse aid dispenser and keep it topped up; it prevents mineral spots on dishes
- Run an extra hot cycle after the baking soda step if deposits remain visible
- Check your water heater temperature. Hotter water (120°F) dissolves minerals better
Common Dishwasher Cleaning Mistakes to Avoid
Even with good intentions, some cleaning habits can damage your dishwasher or make problems worse. Here are mistakes people often make and how to skip them:
| Mistake | Why It’s a Problem | What to Do Instead |
|---|---|---|
| Using harsh chemicals or bleach | Can damage rubber seals and plastic components | Stick to white vinegar, baking soda, or citric acid |
| Skipping the filter entirely | Causes a buildup that reduces cleaning power and creates odors | Clean the filter weekly, deep clean monthly |
| Overloading during a cleaning cycle | Prevents proper water circulation and cleaning | Always run cleaning cycles with an empty dishwasher |
| Ignoring the spray arms | Clogged holes mean dishes won’t get clean | Remove and clean spray arms monthly |
| Using dish soap instead of dishwasher detergent | Creates excessive suds that can overflow and damage the machine | Only use products made specifically for dishwashers |
| Putting hot items directly in | Can warp plastic parts and the tub | Let dishes cool before loading them |
| Neglecting the door gasket | Leads to leaks and mold growth | Wipe down the gasket weekly with a damp cloth |
| Running cold water cycles for cleaning | Doesn’t dissolve grease or kill bacteria effectively | Always use the hottest water setting for deep cleaning |
Tips to Keep Your Dishwasher Clean for a Longer Time
Prevention is always easier than deep cleaning. These simple habits will keep your dishwasher fresh and reduce how often you need to scrub it:
- Scrape off large food pieces before loading dishes
- Rinse plates if they sit for more than a day
- Run hot water at the sink first so the dishwasher starts hot
- Leave the door cracked open after cycles to air out moisture
- Clean the filter weekly with a quick rinse
- Run a vinegar cycle once a month
- Wipe the door gasket and edges weekly
- Use the correct amount of detergent
- Add rinse aid to prevent mineral deposits
- Run full loads instead of half-empty cycles
- Check spray arms monthly for clogs
- Keep the kitchen floor around it clean
- Avoid washing extremely greasy pots and pans
