Learning how to clean your dishwasher properly is something many homeowners overlook — yet it’s one of the most important appliances to maintain. A dirty dishwasher can harbour bacteria, cause unpleasant odours, and even affect how clean your dishes come out. In this guide, we’ll show you exactly how to clean your dishwasher step by step for sparkling results.
Why Cleaning Your Dishwasher Is Important
Many people assume that a dishwasher cleans itself — unfortunately, this isn’t the case. Food particles, grease, limescale, and soap scum all build up over time. According to the US Department of Energy, a well-maintained dishwasher also runs more efficiently, saving both water and energy. Therefore, cleaning your dishwasher monthly keeps it working at its best.
Step 1: Remove and Clean the Filter
First, locate the filter at the bottom of the dishwasher — usually a cylindrical or flat mesh screen. Twist or lift it out (check your manual if unsure). Rinse it under warm running water and use an old toothbrush to remove food debris. Consequently, a clean filter is the single most effective step to improve your dishwasher’s performance and eliminate bad smells.
Step 2: Wipe Down the Interior
Next, use a damp microfiber cloth to wipe down the inside walls, the door edges, and especially the rubber door seal. The seal is a common spot for mould, food residue, and trapped moisture. Use a toothbrush dipped in white vinegar to scrub any mouldy areas. Furthermore, wipe the spray arms and check the holes aren’t blocked — blocked spray arm holes reduce cleaning effectiveness.
Step 3: Run a Vinegar Cycle
Place a dishwasher-safe cup filled with white vinegar on the top rack of the empty dishwasher. Run a full hot cycle. The vinegar works to dissolve limescale deposits, break down grease, and neutralise odours naturally. As a result, your dishwasher will smell significantly fresher after just one cycle. This is also gentle on the dishwasher’s components, unlike some harsh chemical cleaners.
Step 4: Run a Baking Soda Cycle
After the vinegar cycle, sprinkle a cup of baking soda across the bottom of the empty dishwasher. Run a short hot cycle. The baking soda absorbs any remaining odours and helps brighten the interior. Moreover, this two-step process of vinegar followed by baking soda is one of the most effective natural methods for freshening a dishwasher.
Step 5: Clean the Exterior
Finally, wipe down the dishwasher door exterior with an all-purpose spray and a microfiber cloth. Pay attention to the control panel and the door handle. For stainless steel dishwashers, use a stainless steel cleaner to remove fingerprints and smears. In conclusion, a clean exterior completes the look and keeps your kitchen looking tidy.
How Often Should You Clean Your Dishwasher?
Clean the filter every two to four weeks depending on usage. Run a deep clean cycle once a month. Check the spray arms and door seal weekly for buildup. With these simple habits, your dishwasher will run efficiently and keep your dishes spotlessly clean.
