How to clean a dishwasher: expert step by step guide to what to do daily, weekly and monthly

1. To do daily: check for food bits

What you'll need:

• Cloth/kitchen roll (optional; look for value packs, such as this 6-pack of recycled kitchen paper)

What to do:

Pull out the bottom rack and check for food scraps. With the bottom rack of the dishwasher pulled out, look behind it and scan the dishwasher floor for any bits of food that may become stuck in the filter well, screen or heating element. If you see any, use kitchen roll or a cloth (or your fingers, if you're not too squeamish!) to remove them.

2. To do weekly: wipe down the dishwasher door and clean the filter

What you'll need:

• Microfibre cloth (multi-packs can work out cheaper)
• Old, soft toothbrush

What to do:

• Open the door and use a damp microfibre cloth to clean it, wiping the interior surface and around the edges and then wiping the controls area and the handle. Then gently scrub any dirt or gunk from the rubber seal around the door using an old toothbrush and some warm, soapy water.
• Locate and remove the filter. Dishwasher filters are usually located beneath the bottom spray arm – if you're unsure how to remove it, check your dishwasher's user manual or take a look at the manufacturer's website. Once the filter's removed, rinse it under hot water and use a soft toothbrush to scrub both the plastic frame and mesh screen. Then rinse it again to ensure it's completely clean. Replace it in the dishwasher, making sure it's locked securely into place.

3. To do monthly: run a deep-clean cycle

What you'll need:

• Distilled white vinegar (look for larger-size bottles for better value for money)
• 250ml dishwasher-safe cup (like these cups)
• Baking soda/bicarbonate of soda (look for a cleaning-specific pack)

OR

• A pre-prepared dishwasher cleaner such as Dr Beckmann Dishwasher Cleaner or Finish Dishwasher Deep Cleaner with Lemon

What to do:

• Fill the cup with distilled vinegar and place it on the top shelf of the dishwasher. Run the dishwasher on a pots-and-pans cycle without any dishes or detergent.
• Sprinkle a cup of baking soda in the bottom of the dishwasher after the cycle is complete. This will give your dishwasher an even fresher smell.

OR

• Put the pre-prepared dishwasher cleaner into your dishwasher, according to the pack instructions. Run the dishwasher on the suggested cycle. Open the door after the cycle finishes, to let the components finish drying in the fresh air.

Is it OK to use vinegar to clean a dishwasher? Doesn't vinegar ruin a dishwasher?

We asked Sarah Dempsey, to clarify any misconceptions around using vinegar to clean a dishwasher. She said:

"Distilled white vinegar is actually great for helping to loosen stubborn, dried-on food pieces of food and get rid of odours," says laundry and cleaning expert Sarah Dempsey. "But using white vinegar to clean your dishwasher extremely frequently probably isn't wise, as the acid can cause some wear on the components or the rubber seal . Using it once a month should be fine but, if you'd rather remain cautious, choose a specialised dishwasher cleaning solution instead."
