How To Clean Inside Of Stainless Dishwasher – Restore Sparkle
To effectively clean the inside of your stainless steel dishwasher, first empty it completely and remove the filter and spray arms for a thorough hand-wash.
Next, run a hot cycle with a cup of white vinegar placed in a top-rack bowl, followed by a second hot cycle with a cup of baking soda sprinkled on the bottom. Finish by wiping down door seals and edges with a damp cloth.
Your stainless steel dishwasher, a true workhorse in the kitchen, often hides a secret. While it makes your dishes sparkle, its own interior can accumulate grime, food particles, hard water stains, and even mold. This buildup not only looks unsightly but can also impact your dishwasher’s efficiency and leave your dishes less than perfectly clean.
You might be wondering if your dishes are truly sanitary or why that lingering odor just won’t go away. You’re not alone! Many DIY homeowners face this challenge, thinking a machine that cleans itself doesn’t need external help.
This guide will walk you through the precise steps to deep clean the inside of your stainless dishwasher, ensuring it runs efficiently, smells fresh, and delivers sparkling results every time. We’ll cover everything from pre-cleaning to tackling stubborn stains, maintaining gaskets, and ensuring your appliance performs at its peak. Understanding how to clean inside of stainless dishwasher is essential not just for gleaming dishes, but for the longevity and efficiency of the appliance itself.
Get ready to transform your dishwasher from a grimy workhorse into a gleaming, high-performing kitchen essential.
Why Your Stainless Dishwasher Needs Regular Cleaning
Just like any other appliance, your dishwasher requires routine maintenance to function at its best. It might seem counterintuitive since its job is to clean, but debris, grease, and minerals can build up over time. This internal grime can lead to a host of problems that diminish its performance and lifespan.
Understanding Common Dishwasher Woes
Have you noticed cloudy glasses, gritty dishes, or an unpleasant smell wafting from your dishwasher? These are tell-tale signs that it’s time for a deep clean. Food particles, soap scum, and hard water deposits cling to the interior surfaces, spray arms, and filters.
Over time, this accumulation creates an environment where bacteria and mold can thrive, leading to odors and inefficient cleaning cycles. It’s a common issue, and addressing it promptly prevents more significant problems down the line.
The Benefits of a Sparkling Interior
A clean dishwasher isn’t just about aesthetics; it’s about performance and hygiene. When your dishwasher’s interior is free from buildup, water can circulate properly, detergent can dissolve effectively, and your dishes come out truly clean and sanitized.
Regular cleaning also extends the life of your appliance by preventing blockages and reducing strain on its components. Plus, there’s nothing quite as satisfying as opening a fresh-smelling, sparkling clean dishwasher.
Gathering Your Cleaning Arsenal: Tools and Materials
Before you dive into the cleaning process, gather all your supplies. Having everything on hand makes the job quicker and more efficient, allowing you to focus on the task.
Essential Cleaning Supplies
You likely have most of these items already in your pantry or cleaning cabinet. You won’t need harsh chemicals, which can damage stainless steel or leave residues.
Here’s what you’ll need:
- White Vinegar: A natural descaler and deodorizer.
- Baking Soda: Excellent for absorbing odors and gentle scrubbing.
- Soft Cloths or Sponges: For wiping surfaces. Avoid abrasive scrubbers.
- Old Toothbrush or Small Brush: Perfect for reaching tight spots and scrubbing filters.
- Dish Soap: For hand-washing removable parts.
- Measuring Cup: For precise amounts of vinegar and baking soda.
- Protective Gloves: To protect your hands from grime and cleaning agents.
Safety First: Protecting Yourself and Your Appliance
While cleaning a dishwasher is generally safe, a few precautions are always wise. Always disconnect the power to your dishwasher before removing or reattaching any internal components, especially if you plan to access the drain pump.
Wear protective gloves to keep your hands clean and protect them from any mild cleaning solutions or trapped food debris. When using vinegar or baking soda, ensure good ventilation in your kitchen. Never mix vinegar with bleach, as this can create dangerous chlorine gas. For stainless steel surfaces, avoid abrasive cleaners or steel wool, which can scratch the finish.
Pre-Cleaning Prep: Clearing the Decks
A successful deep clean starts with thorough preparation. This initial phase removes the most obvious debris and prepares the interior for a more intensive cleaning.
Emptying and Inspecting
Start by completely emptying your dishwasher. Remove all dishes, racks, and utensil baskets. This gives you unobstructed access to the interior. Take a moment to inspect the bottom of the dishwasher for any large food particles, broken glass, or other debris.
Carefully pick up any solid pieces by hand or with a paper towel. This prevents them from clogging the drain or filter during the cleaning cycles. Look for any obvious signs of mold or mildew, especially around the door seal.
Removing and Rinsing Filters
The dishwasher filter is often the biggest culprit for odors and poor cleaning performance. It traps food scraps and grease, preventing them from recirculating onto your dishes. Many modern dishwashers have a removable filter assembly, usually located at the bottom of the tub.
Refer to your appliance’s manual for specific instructions on how to remove it. Typically, it involves twisting or unlatching a component. Once removed, take the filter to your sink. Rinse it thoroughly under hot running water, scrubbing gently with an old toothbrush and a little dish soap to remove all trapped gunk and grease. Ensure every crevice is clean. Rinse again until the water runs clear.
The Ultimate Guide: How to Clean Inside of Stainless Dishwasher for Peak Performance
Now that your dishwasher is prepped, it’s time for the deep clean. This two-step process uses common household ingredients to tackle grime, hard water, and odors.
Tackling the Interior with Vinegar
White vinegar is a powerful natural cleaner, excellent for dissolving mineral deposits, soap scum, and grease. It also acts as a disinfectant and deodorizer.
Here’s how to use it:
- Ensure the dishwasher is completely empty (no dishes or detergent).
- Place a dishwasher-safe bowl or mug containing one cup of white vinegar on the top rack of your dishwasher. Do not add any detergent.
- Run your dishwasher on its hottest cycle. A “heavy duty” or “sanitizing” cycle works best.
The hot water combined with the vinegar will circulate throughout the dishwasher, breaking down grime and leaving the interior sparkling. The vinegar also helps to clean the internal plumbing, spray arms, and heating element.
The Power of Baking Soda
After the vinegar cycle, it’s time for baking soda. This gentle abrasive helps scrub away any remaining residue and is a fantastic odor absorber.
Follow these steps:
- Once the vinegar cycle is complete, remove the bowl.
- Sprinkle one cup of baking soda directly onto the bottom of the empty dishwasher tub.
- Run a short, hot cycle (like a “rinse and hold” or “light wash” cycle). Again, do not add detergent.
The baking soda will work to polish the stainless steel interior, neutralize any lingering odors, and provide a mild scrubbing action to loosen any stubborn bits the vinegar missed. This combination ensures you know how to clean inside of stainless dishwasher effectively.
Detail Cleaning: Spray Arms, Gaskets, and Door Edges
Even after the two cleaning cycles, some areas need special attention. These nooks and crannies are often overlooked but are crucial for a truly clean appliance.
- Spray Arms: Your dishwasher’s spray arms have small holes that can become clogged with mineral deposits or food particles. If you removed them for cleaning (check your manual), use a toothpick or a small wire to clear any blockages in the spray holes. This ensures an even water distribution during cycles.
- Door Gasket/Seal: The rubber gasket around the dishwasher door is a prime spot for mold, mildew, and food debris to collect. Dampen a soft cloth with a mixture of equal parts white vinegar and water, or a mild all-purpose cleaner. Thoroughly wipe down the entire gasket, paying close attention to the folds and crevices. Use an old toothbrush for hard-to-reach areas.
- Door Edges and Control Panel: Don’t forget the exterior edges of the door and the control panel. Wipe these areas with a damp cloth and a mild cleaner to remove fingerprints, splatters, and dust. For stainless steel exteriors, follow the grain of the steel to avoid streaks.
- Reassemble: Once everything is clean and dry, carefully reattach the filter, spray arms, and racks according to your dishwasher’s manual.
Dealing with Stubborn Stains and Odors
Sometimes, a basic deep clean isn’t enough. Certain issues require a targeted approach to get your stainless dishwasher truly pristine.
Hard Water Spots and Mineral Buildup
Hard water leaves behind unsightly white, chalky mineral deposits, especially noticeable on stainless steel. If the vinegar cycle didn’t completely eliminate them, you might need a bit more elbow grease.
For persistent hard water spots:
- Create a paste with baking soda and a small amount of water.
- Apply the paste directly to the hard water spots on the stainless steel interior.
- Let it sit for 10-15 minutes to allow the baking soda to work on the minerals.
- Gently scrub with a soft, damp cloth or sponge. Avoid abrasive materials.
- Wipe clean with a damp cloth and then dry thoroughly to prevent new spots.
Mold and Mildew Prevention
Mold and mildew thrive in damp, dark environments. If you notice black spots or a musty smell even after cleaning, you might have a persistent mold problem.
To combat and prevent mold:
- Ensure the dishwasher door is left ajar after each cycle to allow air circulation and drying.
- Regularly clean the door gasket, where mold frequently grows.
- For stubborn mold, you can use a small amount of hydrogen peroxide on a cloth, applied directly to the affected area. Let it sit for a few minutes, then wipe clean. Always test in an inconspicuous area first.
Never use bleach directly in your stainless steel dishwasher, as it can react with stainless steel and cause pitting or discoloration.
Eliminating Lingering Odors
Even after cleaning, some odors can persist. This usually points to trapped food debris or a need for better air circulation.
- Check the Drain: Ensure the drain area at the bottom of the dishwasher is clear. Sometimes small food pieces can get stuck just before the drain opening.
- Citrus Boost: For a fresh scent, place a few lemon or orange peels in the utensil basket and run a short rinse cycle. The citrus oils will leave a pleasant aroma.
- Activated Charcoal: If you’re going away for an extended period, place a small bowl of activated charcoal or coffee grounds inside the empty dishwasher to absorb odors while it’s not in use.
With the right approach, even the toughest stains won’t stand a chance when you tackle how to clean inside of stainless dishwasher.
Maintaining a Clean Dishwasher: Beyond the Deep Clean
A one-time deep clean is a great start, but ongoing maintenance is key to keeping your stainless steel dishwasher in top condition. Simple habits can prevent grime buildup and ensure consistent performance.
Daily Habits for a Happier Dishwasher
Incorporate these quick steps into your daily routine to keep your dishwasher fresher between deep cleans:
- Scrape Dishes: Always scrape large food particles off dishes before loading them. There’s no need to pre-rinse unless your dishwasher manual specifically recommends it, but removing solids is crucial.
- Load Properly: Avoid overcrowding. Proper loading allows water and detergent to reach all surfaces effectively.
- Leave Door Ajar: After unloading, leave the dishwasher door slightly ajar for a while. This allows moisture to escape, preventing mold and mildew growth and eliminating stagnant odors.
- Wipe Down Door Edges: A quick wipe of the door seal and edges with a damp cloth after a cycle can prevent buildup.
Monthly Maintenance Checks
Once a month, take a few minutes for these quick checks:
- Inspect and Clean Filter: Even if your dishwasher seems clean, pull out the filter and give it a quick rinse under hot water. This prevents minor clogs from becoming major problems.
- Quick Vinegar Rinse: Run a quick cycle with one cup of white vinegar in a bowl on the top rack. This helps prevent hard water and soap scum buildup.
- Check Spray Arm Holes: Quickly inspect the spray arm holes for any visible blockages and clear them with a toothpick if necessary.
By incorporating these simple habits, you’ll find that the overall task of knowing how to clean inside of stainless dishwasher becomes much less daunting.
When to Call a Pro
While most dishwasher cleaning and minor maintenance can be handled by a DIYer, there are times when professional help is warranted. If you notice persistent issues like:
- Major Leaks: Beyond a few drips, significant leaks can indicate a faulty seal or component.
- Unusual Noises: Grinding, clunking, or excessive vibrating could point to motor or pump issues.
- Failure to Drain: If your dishwasher consistently leaves standing water, there might be a blockage in the drain hose or pump that’s beyond a simple filter clean.
- Electrical Problems: Any flickering lights, tripped breakers, or failure to power on should be addressed by a qualified appliance technician.
Attempting complex repairs without proper knowledge and tools can be dangerous and may void your warranty. When in doubt, call a professional.
