Did you know that properly cleaning your dishwasher can prevent a multitude of kitchen headaches? According to cleaning experts, your dishwasher should be thoroughly cleaned every 30 days to avoid unpleasant odors and the accumulation of detergent, minerals, and grime.
Unfortunately, a neglected dishwasher can significantly impact its performance. Dirty dishwashers often leave plates with stuck-on crumbs and cloudy wine glasses. Additionally, the National Sanitation Foundation states that dishwashers need to reach at least 150°F to kill bacteria efficiently, something that becomes more difficult when the appliance is clogged with residue.
Cleaning your dishwasher doesn’t have to be complicated or expensive. In fact, for just $10-20 and about 15 minutes plus one wash cycle, you can thoroughly sanitize this essential kitchen appliance. This guide will walk you through practical methods for cleaning your dishwasher filter (which can harbor food particles, causing those unpleasant odors), using vinegar and baking soda for natural cleaning, and adequately maintaining the drain to prevent clogs. Whether you’re wondering how to clean a dishwasher naturally or with commercial products, we’ve got you covered.
Why Cleaning Your Dishwasher Matters
Many people mistakenly believe that dishwashers clean themselves during regular cycles. Despite washing dishes with hot water and detergent, your dishwasher accumulates food particles, grease, mineral deposits, and soap scum over time. If left unchecked, this buildup can significantly hinder your appliance’s performance and lifespan.
1. How grime and food buildup affect performance
When the dishwasher filters don’t collect food waste and fatty deposits, they end up in the internal system. These particles can clog vital components, making it difficult for the unit to dispense fresh water or extract soiled water properly. Furthermore, food residue becomes a breeding ground for bacteria and mold, potentially transferring germs from plate to plate during wash cycles.
Built-up residue inside the dishwasher tub impedes water movement, preventing it from reaching every inch of your dishes. Consequently, you’ll notice unsatisfying results, with some items left completely untouched after a cycle. Food buildup within drainage pipes creates stubborn blockages that could eventually make it impossible for the unit to drain, resulting in leaks or costly repairs.
The efficiency of your dishwasher detergent also suffers when minerals in hard water interact with cleaning agents, reducing their ability to create a rich lather and clean effectively. Notably, scale accumulation on the heating element acts as insulation, making water heating less efficient and increasing energy consumption and electricity bills.
2. Common signs your dishwasher needs cleaning
Your dishwasher sends clear signals when it needs attention. Watch for these indicators:
- Dirty or cloudy dishes after a complete cycle, especially with a white powdery substance on glassware
- Unpleasant odors emanating from the appliance, typically caused by food particles trapped in the filter
- Water is not draining correctly, with pooling at the bottom of the dishwasher
- Visible residue or a rough coating inside the dishwasher
- Clogged spray arm holes prevent free movement when manually pushed
You should check and clean your dishwasher filter after every use and sanitize your dishwasher at least once a week. For thorough maintenance, experts recommend removing the racks and filters monthly and cleaning them with warm water and dish soap.
If you’ve cleaned the filter but still notice standing water or slow drainage, this may indicate a more serious problem that requires professional attention. Regular maintenance prevents substantial food waste accumulation, grease buildup, complex water scaling, and soap scum residue, which gradually decrease your machine’s efficiency.
Understanding how to clean a dishwasher filter is particularly crucial for effective dishwasher cleaning. This component collects food particles, dirt, and grease, quickly becoming a breeding ground for bacteria if neglected. With proper care, your dishwasher will continue delivering spotless results while extending its functional lifespan.
Step-by-Step: How to Clean the Inside of Your Dishwasher
Regular maintenance of your dishwasher’s interior components ensures optimal performance and extends the life of your appliance. Follow these steps to clean each part of your dishwasher’s interior thoroughly.
Step 1: Remove and clean the filter
Most dishwashers have a filter at the bottom that requires monthly cleaning to prevent odors and clogs. First, remove the bottom rack to access the filter, typically located in the back corner or around the base of the bottom spray arm. For two-part filters, turn the upper filter a quarter turn counterclockwise and lift it out, then gently pull the lower filter forward.
- A clogged filter reduces water flow and cleaning efficiency.
- Monthly cleaning helps eliminate grease buildup and trapped food.
- Always refer to your dishwasher manual for filter location and removal tips.
Soak the filter in hot water with a few drops of dish soap containing a degreaser. Use a soft brush or an old toothbrush to scrub away food debris and calcium deposits gently. Never use wire brushes or scouring pads, as they can damage the filter. Rinse thoroughly under warm water before reinstalling, ensuring it locks securely in place.
Step 2: Wipe down spray arms and racks
The spray arms distribute water throughout your dishwasher and can become clogged with food or mineral deposits. To clean them, unscrew or unclip the upper and lower spray arms. Once removed, use a toothpick or cocktail stick to clear any blocked nozzles. Soak the arms in a vinegar solution to dissolve food particles and rinse them with soapy water for stubborn clogs.
Inspect the bottom of the dishwasher tub and wipe up any debris with paper towels or a cloth. Remember to clean the area where the spray arm attaches as well.
Step 3: Clean the door, gasket, and seals
The door gasket forms a crucial seal that prevents water leakage. Clean around the rubber gasket with an old, soft toothbrush and a solution of three cups of hot water mixed with half a cup of vinegar. Some manufacturers recommend cleaning only with warm water; hence, check your manual before using cleaning solutions.
- Always inspect for food debris or buildup in the gasket folds.
- After brushing, use a soft cloth to wipe away loosened grime.
- Avoid bleach-based cleaners as they can weaken rubber over time.
You may need a specialized cleaner for stubborn mold or mildew on gaskets, but always follow the manufacturer’s instructions to avoid damaging the rubber. Wipe down the interior door panel as well to remove any residue.
Step 4: How to clean the dishwasher drain safely
Before cleaning the drain, turn off the breaker or unplug the dishwasher for safety. Remove the filter as described earlier. Add 1/4 cup of baking soda to the drain for minor cleaning, followed by 1/2 cup of distilled vinegar. The resulting foam helps loosen debris. Let this mixture work for 10-15 minutes.
- Always wear gloves when handling buildup or drain debris.
- Use only distilled white vinegar to prevent residue buildup.
- Do not run the dishwasher during this foam-cleaning process.
For more serious clogs, you may need to locate and disconnect the drain hose according to your dishwasher’s manual. Never use a plumber’s snake, as its cutting motion could puncture your dishwasher. Instead, blow through the hose to check for clogs and carefully remove debris with a straightened wire coat hanger if needed.
Natural Methods: How to Clean a Dishwasher Effectively
Natural cleaning solutions provide an effective alternative to commercial products for maintaining dishwashers. These household ingredients clean efficiently and generally cost less than store-bought cleaners.
1. How to clean a dishwasher with vinegar
Learning how to clean a dishwasher with vinegar is one of the most effective natural methods, as white vinegar works wonders on dishwasher interiors thanks to its acidic properties that break down grease and grime. Nevertheless, you should use this method cautiously:
- Empty the dishwasher completely
- Place one cup of white vinegar in a dishwasher-safe bowl or cup
- Position the container upright on the top rack (never pour vinegar directly into the detergent dispenser)
- Run a hot water cycle without detergent
- Skip the drying cycle and open the door to let it air-dry
Although vinegar effectively eliminates odors and breaks down residue, overuse could damage rubber seals over time due to their acidic nature.

2. How to clean a dishwasher with the baking soda method
Learning how to clean a dishwasher with the baking soda method is essential for odor elimination, as baking soda serves as an excellent deodorizer and gentle abrasive cleaner:
- Sprinkle one cup of baking soda across the bottom of your empty dishwasher
- Let it sit for 30-60 minutes to absorb odors
- Run a short cycle on the hottest setting without detergent
- Allow to air-dry with the door open
For a deeper clean, when learning the baking soda technique for cleaning a dishwasher, you can create a baking soda paste (½ cup baking soda with 1-2 tablespoons of water) to clean the filter effectively. Apply the paste to the filter and gently scrub with an old toothbrush before rinsing.
3. Using lemon or citrus for a fresh smell
Lemons provide a natural, refreshing scent indeed while offering cleaning benefits:
- Cut a lemon in half and remove all seeds
- Place the halves face-up on the top rack of your dishwasher
- Run a regular cycle with your dishes
The citric acid in lemons helps disinfect, remove limescale, and add shine to glassware. Similarly, this method leaves behind a pleasant aroma rather than chemical smells. For optimal results, alternate between these natural cleaning methods monthly to keep your dishwasher functioning efficiently and smelling fresh.
Using Dishwasher Cleaners for Deep Cleaning
Commercial dishwasher cleaners offer a convenient alternative when natural solutions are insufficient to tackle tough buildup. If you’ve tried learning how to clean a dishwasher with natural methods but need stronger solutions, these products deliver professional results. These specialized products are formulated specifically to address problems that homemade remedies might struggle with.
1. When to use commercial cleaners
Consider using commercial dishwasher cleaners whenever you notice persistent issues after trying natural methods. These products are specially formulated to tackle limescale and mineral buildup that can accumulate over time. They’re invaluable if you live in an area with hard water, as mineral deposits form more rapidly.
Look for these signs indicating it’s time for a commercial cleaner:
- Cloudy glassware that doesn’t improve with vinegar treatment
- Visible scale buildup on heating elements and internal components
- Persistent unpleasant odors despite regular cleaning
- Reduced cleaning performance despite a clean filter
Commercial cleaners are ideal for regular maintenance as they effectively remove grease and grime while requiring less scrubbing effort.
