One of the easiest ways to clean a dishwasher is by starting with the removable parts. Take out the utensil holder and dishwasher racks and rinse or wipe them to remove bits of food.
If foods are caked-on, fill your sink half full of warm water and add two cups of white vinegar. Vinegar is natural and safe to use in your dishwasher and works as a DIY dishwasher cleaner. Place the parts in the sink and let them soak for 20 minutes. Then rinse them and put them back in place.
Grime can accumulate inside a dishwasher until your dishes no longer get properly clean. Built-up grime can also cause unpleasant odours and dishwasher pump repair.
Deep clean the dishwasher with vinegar and dishwasher soap to eliminate the grime and odours. First, empty the dishwasher. Then put a cup of white vinegar in a dishwasher-safe bowl and place it on the top rack of the dishwasher. Run the hottest washing and drying cycle on the dishwasher.
You can also use bleach to deep clean the interior of a dishwasher and remove tough stains, mould and mildew if the dishwasher is not stainless steel and does not contain stainless steel. Pour a cup of bleach into a dishwasher-safe, bleach-safe bowl and place it on the top rack of your dishwasher. Then run a full cycle, but skip the drying cycle.
Remember: Do not use bleach in a stainless steel dishwasher or a dishwasher that contains stainless steel, as bleach will damage it. Also, do not use bleach at the same time you clean with vinegar.
