Your dishwasher is one of the hardest-working appliances in your Glasgow kitchen. Day after day, it tackles greasy plates, baked-on food, and coffee-stained mugs. But like any appliance, it needs regular cleaning to perform at its best. A dirty dishwasher not only cleans less effectively but can also develop unpleasant odours, limescale buildup, and even mould.
At BuZy Bees Cleaning, we include dishwasher cleaning in our kitchen deep cleans. In this guide, we show you how to clean your dishwasher thoroughly and maintain it for optimal performance.
Why Dishwasher Cleaning Matters
A neglected dishwasher can:
- Leave dishes with a cloudy film or food residue
- Produce musty or sour odours
- Develop limescale that reduces efficiency
- Clog spray arms and filters, affecting water circulation
- Harbour bacteria and mould in hidden areas
A dirty dishwasher can harbour more bacteria than a kitchen sink. Regular cleaning is essential for hygienic dishwashing. — Food Safety Research UK
Key Factors for Effective Dishwasher Cleaning
Water Hardness
Glasgow’s moderately hard water means limescale buildup is common. Regular descaling keeps your dishwasher efficient.
Usage Frequency
Daily use leads to faster grease and food particle accumulation. Weekly cleaning is recommended for busy households.
Detergent Type
Quality dishwasher tablets and rinse aid improve cleaning performance and reduce residue buildup.
How to Clean Your Dishwasher: Step-by-Step
Step 1: Clean the Filter
- Remove the bottom rack — Pull it out completely to access the filter.
- Remove the filter — Twist and lift out the cylindrical filter at the base of the dishwasher.
- Rinse under warm water — Remove food particles and debris.
- Scrub with a brush — Use an old toothbrush to remove stubborn grease.
- Check the filter housing — Wipe the area where the filter sits with a damp cloth.
- Replace the filter — Ensure it clicks back into place securely.
Step 2: Clean the Spray Arms
- Remove spray arms — Twist and pull them off (check your manual for specific instructions).
- Rinse under water — Flush out food particles from the holes.
- Clear blockages — Use a toothpick or pipe cleaner to remove debris from clogged holes.
- Replace — Ensure they spin freely when pushed.
Step 3: Clean the Door Seal and Edges
- Inspect the seal — Check the rubber gasket around the door for food debris and mould.
- Wipe with vinegar solution — Mix equal parts white vinegar and water. Wipe thoroughly.
- Scrub mould if present — Use a paste of bicarbonate of soda and water with an old toothbrush.
- Wipe the door edges — Clean the inside of the door and the area around the seal.
Step 4: Run a Cleaning Cycle
- Empty the dishwasher — Ensure no dishes are inside.
- Place a cup of white vinegar — Put it upright on the top rack.
- Run a hot cycle — Use the hottest setting available.
- Follow with bicarbonate of soda — Sprinkle 1 cup across the bottom of the empty dishwasher.
- Run a short hot cycle — This deodorises and removes any remaining stains.
:::tip Alternative Method Use a commercial dishwasher cleaner tablet instead of vinegar and bicarbonate of soda. Follow the manufacturer’s instructions for best results. :::
Step 5: Wipe the Exterior
- Clean the door front — Use a damp cloth with washing-up liquid solution.
- Polish the handle — High-touch area that collects fingerprints and bacteria.
- Wipe the control panel — Use a slightly damp cloth to avoid damage.
- Clean around the dishwasher — Wipe the floor and adjacent cabinets.
Dishwasher Cleaning Schedule
| Task | Frequency | Why It Matters |
|---|---|---|
| Scrape plates before loading | Every wash | Prevents filter clogs |
| Check and clean filter | Weekly | Maintains water flow |
| Wipe door seal | Weekly | Prevents mould and odours |
| Run cleaning cycle | Monthly | Removes limescale and grease |

| Deep clean exterior | Monthly | Keeps kitchen looking tidy |
| Professional descale | Every 6 months | Tackles hard water buildup |
Tips for Keeping Your Dishwasher Clean
- Scrape plates before loading — Remove large food particles to prevent filter clogs.
- Do not pre-rinse excessively — Modern dishwashers need some grease to activate detergents effectively.
- Load correctly — Face dishes towards the spray arms and avoid overcrowding.
- Use rinse aid — Prevents water spots and improves drying.
- Run hot water before starting — Turn on the kitchen tap until hot water flows, then start the dishwasher.
- Leave the door ajar after cycles — Allows air circulation and prevents moisture buildup.
- Use the right detergent — Quality tablets or powder work better than cheap alternatives.
:::tip Pro Tip If your dishwasher smells bad despite regular cleaning, check the drain hose. A clogged or improperly installed drain hose can cause odours to back up into the dishwasher. :::
