At a Glance
If you’ve ever opened your dishwasher expecting clean dishes and instead found cloudy glassware or a lingering odor, you’re not alone. Most people think they know how to clean a dishwasher, but small mistakes can actually make things worse over time.
Properly cleaning your dishwasher clean matters. A poorly maintained dishwasher doesn’t just affect cleanliness. It can lead to mechanical issues, higher energy use, and even early appliance failure. What starts as a simple cleaning oversight can turn into an expensive repair.
At John’s Appliance, we regularly help customers troubleshoot these exact problems and show them how to maintain their appliances properly so they last longer and perform better.
Our aim today is to help you. Here are some of the points we will discuss:
- The biggest mistakes people make when learning how to clean a dishwasher
- What actually works for dishwasher deep clean steps and long-term care
The Cost of Improper Dishwasher Maintenance
It’s easy to assume your dishwasher cleans itself. After all, it runs hot water and detergent through every cycle. But without proper care, residue, grease, and mineral deposits slowly build up inside the machine.
That buildup affects more than just appearance. Food particles and grease can coat internal components, reducing efficiency and forcing the appliance to work harder. Over time, such buildup puts strain on the heating element and water sensors, which are critical for proper cycle performance.
You may also start to notice issues like dishwasher smell removal becoming more difficult. That’s often a sign that debris is trapped somewhere inside, recirculating during each wash.
There’s also a financial angle. Ignoring routine cleaning can lead to clogged drains, worn-out parts, and service calls that could have been avoided. Compared to that, a simple routine using proper dishwasher deep clean steps is quick, inexpensive, and effective.
The goal here isn’t just surface cleaning. It’s understanding how to clean a dishwasher thoroughly so it performs like it should.
Mistake 1: Ignoring the Manual Filter Assembly
One of the most common mistakes is skipping dishwasher filter cleaning altogether.
Many modern dishwashers use manual filters instead of self-cleaning grinders. These filters, often shaped like a cylindrical filter at the bottom of the tub, are designed to trap food particles before they recirculate. When they’re clean, your dishes come out spotless. When they’re clogged, those particles get pushed right back onto your dishes.
If you’ve ever noticed gritty residue or a persistent odor, the filter is usually the culprit.
Cleaning it is simple:
- Remove the bottom rack
- Twist and lift out the filter assembly
- Rinse under warm water
- Soak if needed, then gently scrub with a soft brush
Avoid using harsh scrubbers that could damage the mesh. Once clean, reinstall it securely.
Neglecting this step is one of the fastest ways to end up needing more intense dishwasher smell removal solutions. A dirty filter doesn’t just smell awful. It actively reduces cleaning performance.
Mistake 2: Overusing Vinegar and Acidic Solutions
A lot of advice online recommends cleaning a dishwasher with vinegar, and while vinegar can help in some cases, it’s not the perfect solution people think it is.
The problem is acidity. Frequent use of vinegar can slowly degrade rubber components, especially when it comes to dishwasher gasket care. Over time, this can lead to leaks or seal failure.
It’s also common to see people combine vinegar and baking soda in the same cycle. While it looks effective, the chemical reaction actually neutralizes both substances, reducing their cleaning power.
For tougher issues like hard water buildup in dishwasher, a better option is using citric acid for dishwashers or a specialized cleaner designed for appliance use. These products are formulated to remove mineral deposits without damaging internal components.
If you’re looking for the best dishwasher cleaner, choose one that balances effectiveness with material safety rather than relying solely on DIY solutions.
| Cleaning Method | Grease Removal | Limescale Removal | Safe for Rubber | Cost Per Use | Ease of Use |
|---|---|---|---|---|---|
| Vinegar | Moderate | Light | Moderate risk | Low | Easy |
| Baking Soda | Light | Minimal | Safe | Low | Easy |
| Vinegar + Baking Soda | Low (neutralized) | Low | Safe | Low | Easy |
| Citric Acid | High | High | Safe | Moderate | Easy |
| Commercial Cleaner | Very High | Very High | Designed safe | Moderate | Very Easy |
For consistent results, most homeowners benefit from alternating between DIY methods and commercial cleaners depending on the level of buildup.
Mistake 3: Neglecting the Spray Arms and Air Gap
Even if you’ve mastered how to clean a dishwasher, it’s easy to overlook hidden components.
The spray arms are one of the most important parts of your dishwasher. These rotating arms distribute water during the cycle, and if their small jets get clogged, water flow becomes uneven. That means dishes won’t get fully cleaned.
To fix this, remove the spray arms and check each hole. Use a toothpick or small tool to gently clear any debris. The simple act of remembering to clean dishwasher spray arms properly can dramatically improve performance.
Another often-missed component is the air gap. This small device, usually located near your sink, prevents dirty water from flowing back into the dishwasher. Without proper maintenance of the dishwasher air gap, clogs can form and cause drainage issues.
If your dishwasher isn’t draining properly or you need to unclog dishwasher drain, checking the air gap is a smart first step.
Ignoring these areas means your dishwasher can’t operate at full capacity, no matter how clean the interior looks.
The Proper Way: How to Clean a Dishwasher Step-by-Step
Now that you know what to avoid, here’s the right approach to how to clean a dishwasher from top to bottom.
Step 1: Empty and Prep
Remove all dishes and racks if needed. Check for visible debris and wipe down accessible areas, including door tracks and the detergent dispenser.
Step 2: Filter and Spray Arms
Perform thorough dishwasher filter cleaning and clean dishwasher spray arms as described earlier. This is where most performance issues start.
Step 3: Interior Cleaning Cycle
Run a cleaning cycle using a recommended cleaner or citric acid for dishwashers. This helps break down grease, mineral buildup, and odors.
If needed, you can occasionally try cleaning dishwasher with vinegar, but not as a primary method.
Step 4: Exterior Finish
Wipe down the exterior, especially if you have a stainless model. Cleaning stainless steel dishwasher interior surfaces also helps maintain appearance and hygiene.
Don’t forget small details like the float switch and door seals when doing a deeper clean.
How Often Should You Clean Your Dishwasher?
Keeping up with a consistent cleaning schedule makes a big difference in dishwasher performance and helps prevent odors, drainage issues, and buildup. If you’re learning how to clean a dishwasher properly, use this routine as a simple maintenance guide:
- Clean the filter every 1–2 weeks, especially if you use your dishwasher often or load heavily soiled dishes.
- Run a full interior cleaning cycle once a month to remove grease, residue, and hard water buildup.
- Check and clear the spray arms every 1–2 months to keep water flowing strongly and evenly.
- Do a deep clean every 3–4 months for a more complete maintenance reset.
Following these dishwasher maintenance tips helps your appliance run more efficiently, smell fresher, and last longer.
Maintaining a Like-New Dishwasher for Years

Frequently Asked Questions about Dishwasher Cleaning
Clean your dishwasher filter every 1–2 weeks to help maintain strong performance and prevent odors. If you run your dishwasher daily or wash heavily soiled dishes, check it more often to avoid food buildup.
Only use bleach if your dishwasher does not have stainless steel parts. Bleach can damage stainless steel interiors and should never be mixed with other cleaners, since it can create harmful fumes.
The best way to remove hard water stains is to use citric acid for dishwashers or a commercial dishwasher cleaner designed for mineral buildup. Running a monthly cleaning cycle can also help prevent new stains from forming.
A rotten egg smell usually means food, grease, or bacteria is trapped in the filter, drain system, seals, or air gap. If the odor continues after routine cleaning, your dishwasher may need a deeper clean to remove hidden buildup.
Yes, occasionally. A bowl of vinegar can help reduce light odors and residue, but frequent use may wear down rubber components over time. For regular maintenance, use a dishwasher-safe cleaner made for appliance care.
Your dishwasher spray arms may be clogged if dishes come out dirty, water pressure seems weak, or the top and bottom racks clean unevenly. Remove the spray arms and clear any blocked holes to restore better water flow.
