How to clean a dishwasher in 5 simple steps

A clean dishwasher is crucial for clean dishes, but it is yet another often overlooked appliance when it comes to our cleaning routines.

However, bits of food, grease and grime can easily clog up inside the machine, which can leave unsightly marks on plates and glasses, create bad odours, and ultimately damage your dishwasher.

This includes regularly removing bits of food from inside the filter well – either after every load or whenever you notice debris – and wiping down the doors inside and out to get rid of any dirt or drips.

How to clean a dishwasher

1. Start your dishwasher deep clean by removing all the racks and utensil holders, along with the filter, which you can clean separately.

2. Wipe down the interior of your dishwasher, taking care to remove any visible food particles and debris, and paying particular attention to the spray arms and bottom of your machine. A toothbrush can be handy to help remove any bits of food that are lodged into your dishwasher.

3. Run a cleaning cycle in your machine; you could opt for a specialist dishwasher cleaner, which will contain chemicals to dissolve and clean away any grease and grime, or opt for a natural alternative, such as white vinegar or baking soda, to leave the interior of your dishwasher spotless.

4. Once this is complete, you can clean the dishwasher door – both inside and out. Simply wipe down with a damp microfiber cloth or sponge, and take particular care if the interior of your dishwasher is stainless steel, as some cleaning products – including bleach-based products – may cause damage.

5. Replace the clean racks and utensil holders to finish.

How to clean a dishwasher filter

You will find your dishwasher filter at the bottom of your machine, simply pull out the bottom drawer to access it, and check the owner's manual for details on how to remove – some will twist off, while others will require tools to unscrew them.

Once removed, rinse the filter under water and use a soft toothbrush to remove any food remnants stuck on it, before rinsing clean and locking it back into place. Alternatively, you could leave the filter to soak in warm water with a cup of white distilled vinegar for 30 minutes while you give the rest of your dishwasher a deep clean.
