How to Deep Clean Dishwasher for Maximum Efficiency and Hygiene

Your dishwasher works hard to keep your dishes clean, but how often do you return the favor? Knowing how to deep clean dishwasher is essential not only for sparkling dishware but also to prolong the life of one of your kitchen’s most vital appliances.

At Top Tier Cleaners, we know that a neglected dishwasher can quickly turn into a breeding ground for bacteria, mold, and unpleasant odors. So whether you’re tackling daily mess or going in for a full-scale scrub, this guide covers everything you need to know—from supplies to troubleshooting. Why You Should Deep Clean Your Dishwasher Dishwashers are self-cleaning in theory, but over time, food particles, grease, detergent residue, and hard water minerals build up in the filter, spray arms, and seals. This buildup can lead to: Reduced cleaning efficiency Bad smells Clogged parts and water flow issues Shortened appliance lifespan Knowing how to deep clean dishwasher regularly helps prevent these issues while keeping your dishes truly clean and hygienic. What You’ll Need You don’t need fancy equipment. Most of the best cleaning tools are already in your kitchen: White vinegar Baking soda Dish soap Microfiber cloth or sponge Rubber gloves (optional) Old toothbrush or small brush Dishwasher-safe bowl Toothpick or small wire Commercial dishwasher cleaner (optional) Step-by-Step: How to Deep Clean Dishwasher Let’s break down the process of deep cleaning into manageable steps that should be done monthly—or more often if you use your dishwasher daily. Step 1: Empty and Inspect Remove all dishes and utensil holders. Inspect the bottom of the dishwasher for food scraps or debris. Use a paper towel to clear out any particles from the drain area. Step 2: Clean the Filter One of the most important steps in learning how to deep clean dishwasher is understanding how to clean the filter. Remove the bottom rack and twist out the filter (check your manual). Rinse the filter under hot water. Use an old toothbrush and dish soap to scrub away grease or debris. Rinse again and reinstall. Step 3: Clear the Spray Arms Spray arms push water through small holes. If those holes are clogged, cleaning efficiency drops. Remove the spray arms if possible. Use a toothpick to clear out any mineral deposits or food debris. Rinse thoroughly before reinstalling. Step 4: Wipe Down the Interior Use a damp sponge and a few drops of dish soap to wipe the interior walls, door, and seals. Pay attention to the rubber gasket around the door—it’s a hotspot for mold and food particles. Step 5: Run a Vinegar Wash Now we begin the "deep" part of how to deep clean dishwasher: Place a dishwasher-safe bowl filled with 2 cups of white vinegar on the top rack. Run a hot water cycle with no detergent or dishes. The vinegar breaks down grease, food particles, soap scum, and hard water deposits. Step 6: Follow with Baking Soda After the vinegar cycle: Sprinkle 1 cup of baking soda on the bottom of the dishwasher. Run a short hot water cycle. Baking soda neutralizes odors and provides extra scrubbing power for lingering grime. Step 7: Tackle Stubborn Buildup (Optional) If you’re still noticing greasy or chalky residue: Use a commercial dishwasher cleaner following package directions. For stainless steel interiors, polish with a microfiber cloth and a stainless-steel-safe cleaner. Cleaning Specific Parts Here’s a closer look at areas that require monthly or quarterly attention: Filter Rinse and scrub monthly to prevent clogs. Spray Arms Unclog the holes to maintain water flow and pressure. Door Gasket Wipe down weekly to prevent mold and improve sealing. Exterior Use a microfiber cloth with dish soap or stainless steel cleaner weekly for a streak-free shine.

Here are common problems and quick fixes: Dishes aren’t clean – Clean the filter and spray arms. Standing water – Check for clogged drain or drain hose. Odors – Wipe seals and run a vinegar cycle.
