With all the potential health hazards accompanying a dirty dishwasher, giving it the proper cleaning and maintenance it needs is necessary.

Fortunately, it is easy to clean your dishwashers, and everything you need is in your pantry.

Simple and Easy Steps on How to Clean Dishwasher

Here are some easy steps to clean your dishwasher without hassle. Include them in your kitchen cleaning routine so that you always have a clean and fresh dishwasher.

How to Clean Dishwasher Daily and Weekly

Clean your dishwasher of any remaining pieces of food, beans, pasta, and other every dishwashing cycle. To do this, pull them out of the bottom rack and look for any food debris that got into the well.

Removing them will prevent odours and further build-up. You can wipe the grime door once a week. Premium Clean recommends wiping away any residue or spots right away with a damp cloth or sponge on the interior surface of the door, handle, or dishwasher controls.

Another important part of the dishwasher is the filter. Remove and rinse it weekly to prevent the accumulation of pesky odours. Unlock the filter below its spray arm at the bottom and rinse it in hot water.

Scrub the mesh screen and plastic frame with a toothbrush to remove the grease stuck on its crevices. Check the manufacturer’s manual if this is the first time you will locate the filter.

How to Clean Dishwasher Monthly

Whether you are using a dishwasher cleaning tablet or a homemade cleaning solution, removing any residue and mineral buildup is important. Pour two cups of white distilled vinegar on the dishwasher’s top rack and run it on a normal cycle without any load or detergent.

Commercially prepared dishwashing cleaners have surfactants that easily break down debris and grease. Read the instructions thoroughly to prevent damage to the dishwasher.

Other Things to Clean on Your Dishwasher

Aside from cleaning the dishwasher’s interior, you should also clean its other parts.

Polishing Stainless-Steel Exterior

Fingerprints can make your dishwasher look dull and grimy, especially on stainless appliances. Use a stainless-steel cleaner to remove the streak and leave a shiny surface. It can also repel future dirt and smudges. Do not use any abrasive cleaner or pads to avoid scratching the exterior of the dishwasher.

Cleaning the Accessories and Parts

Remove the dishwasher racks and utensil holders. Wipe away any food debris and scrub the clogs on the spray arm with a soft brush and toothbrush.

Clean the tub by running a full cycle on an empty dishwasher with a detergent. It will thoroughly clean the interior.

Some water types can leave deposits and mineral buildup on the dishwasher. Lemon juice can remove them. Pour a cup in the basket or at the top of the rack and run a normal cycle. The acid in the lemon can remove hard water spots and iron buildup. It can also be helpful in your other kitchen cleaning chores.


Most dishwashers have a built-in self-cleaning function. However, it is unreliable, and you should know how to clean the dishwasher yourself. It will help keep the efficiency of this appliance.

If you let grime and dirt build up, it can potentially damage the dishwasher and pose serious health risks. Use these tips on how to clean dishwashers properly to enjoy the convenience that your dishwasher brings for a long time.
