How Do I Clean a Dishwasher: A Comprehensive Guide
Dishwashers are a modern kitchen marvel, saving time and effort while keeping your dishes sparkling clean. However, like any appliance, they require regular maintenance to perform at their best. Over time, grease, food particles, soap scum, and mineral deposits can build up, leading to odors, poor cleaning performance, and even potential breakdowns. In this detailed guide, we’ll walk you through the step-by-step process of cleaning your dishwasher, share expert tips, and provide additional insights to keep it running efficiently. Let’s dive in!

Why Cleaning Your Dishwasher Matters
Before we get into the how-to, it’s worth understanding why this task is essential. A dishwasher might seem self-cleaning since it washes dishes with hot water and detergent, but that’s a common misconception. “Food debris, grease, undissolved detergent, and water minerals can build up inside your dishwasher, affecting its performance,” explains the team at Whirlpool, a leading appliance manufacturer. Regular cleaning prevents clogs, eliminates odors, and extends the life of your machine.
Neglecting maintenance can also lead to costly repairs. Hard water, in particular, can leave limescale deposits that damage internal components. By dedicating just 30 minutes every month or two, you can keep your dishwasher in top shape.

Step-by-Step Guide to Cleaning Your Dishwasher
Step 1: Empty and Inspect the Dishwasher
Start by removing all dishes and utensils. Check the bottom of the dishwasher for any visible debris—think food scraps, small bones, or even broken glass. “Carefully remove any debris you find,” advises the experts at Good Housekeeping, “and wear gloves if you’re dealing with anything sharp” [(( Good Housekeeping ))]. This step ensures nothing interferes with the cleaning process.
Next, inspect the drain area at the bottom. If it’s clogged, use a paper towel or cloth to clear it out.
Step 2: Clean the Filter
Most dishwashers have a removable filter near the bottom. This component traps food particles, so it’s a prime spot for buildup. “Twist or unclip the filter to remove it, then rinse it under warm, soapy water,” instructs Maytag’s official guide. Use a toothbrush to scrub away stubborn gunk, then reinstall it securely. Some filters are dishwasher-safe—check your manual to confirm.
Not sure where your filter is? Refer to your dishwasher’s user manual (often available online via the manufacturer’s website).
Step 3: Wipe Down the Interior
Using a damp sponge or cloth dipped in warm, soapy water, wipe the door, edges, and rubber gasket. These areas can harbor mold and mildew if neglected. For tough stains, a vinegar-soaked cloth works wonders. Avoid abrasive scrubbers, as they can scratch stainless steel or plastic surfaces.
Step 4: Run a Vinegar Cycle
Vinegar is a natural descaler and deodorizer, perfect for tackling limescale and odors. “Place a dishwasher-safe cup filled with 2 cups of white vinegar on the top rack,” recommends Bob Vila, a trusted home improvement resource [(( Bob Vila ))]. Run a hot water cycle (no dishes inside). The vinegar will break down grease and mineral deposits as it circulates.
Step 5: Follow with Baking Soda
After the vinegar cycle, sprinkle 1 cup of baking soda across the bottom of the dishwasher. Run a short, hot cycle. “Baking soda neutralizes odors and leaves the interior fresh,” notes the team at Real Simple. This step enhances the cleaning power and tackles any lingering smells.
Step 6: Clean the Spray Arms
The spray arms—the rotating parts that distribute water—can get clogged with debris or limescale. Remove them (most unscrew or pop off) and rinse under running water. Use a toothpick or toothbrush to clear the tiny holes. “If the holes are blocked, water can’t circulate properly, and your dishes won’t get clean,” warns Consumer Reports.
Step 7: Exterior Wipe-Down
Finish by cleaning the control panel and door handle with a damp cloth and mild soap. For stainless steel models, a specialized cleaner or a mix of vinegar and water prevents streaks. Dry with a microfiber cloth for a polished look.

Extra Tips for Optimal Dishwasher Care
- Run Hot Water First: Before starting a load, run your kitchen faucet on hot until the water heats up. This ensures the dishwasher fills with hot water from the start, improving cleaning efficiency.
- Use the Right Detergent: Cheap detergents can leave residue. Opt for high-quality tablets or gels recommended by your dishwasher’s manufacturer.
- Combat Hard Water: If you live in a hard water area, consider a rinse aid or a monthly descaling product to prevent buildup.
- Leave the Door Ajar: After each cycle, let the dishwasher air out to prevent moisture buildup and mold growth.

How Often Should You Clean Your Dishwasher?
The frequency depends on usage. “For a household that uses the dishwasher daily, cleaning it once a month is ideal,” suggests the Kitchn [(( The Kitchn ))]. For lighter use, every two to three months suffices. Watch for signs like funky smells or cloudy dishes—they’re your cue to clean sooner.

FAQ: Common Dishwasher Cleaning Questions
Q: Can I use bleach instead of vinegar?
A: Bleach can disinfect, but it’s not recommended for most dishwashers, especially those with stainless steel interiors, as it may cause corrosion. Stick to vinegar or a manufacturer-approved cleaner.
Q: Why does my dishwasher still smell after cleaning?
A: Check the filter or drain for trapped debris. Persistent odors might also signal a plumbing issue—consult a professional if the problem persists.
Q: How do I know if my dishwasher needs descaling?
A: Look for white, chalky residue on dishes or inside the machine. This indicates limescale from hard water, which vinegar or a descaler can address.
Q: Are commercial dishwasher cleaners worth it?
A: Products like Affresh or Finish Dishwasher Cleaner are formulated to tackle tough buildup and can be more effective than DIY methods for heavy-duty cleaning. They’re a good occasional supplement.
Q: Can I clean the dishwasher with dishes inside?
A: No, always clean it empty. Detergents and vinegar cycles are meant for the machine, not your dishes.
