Your dishwasher cleans your dishes but never cleans itself. Think about that for a second. The machine your family relies on to sanitize plates, cups, and utensils that go directly into your mouths is almost certainly harboring mold, grease buildup, and trapped food debris right now. If you have never thought about how do I clean the dishwasher with vinegar, the answer is simple, fast, and long overdue.
The inside of a dishwasher is warm, dark, and wet between cycles. That is the exact environment mold and bacteria love. The rubber gasket around the door, the filter at the bottom, the spray arm holes, the corners of the detergent dispenser. All of these collect residue over time, and all of them affect how clean your dishes actually get.
Start with the Filter
Most modern dishwashers have a removable filter at the bottom of the tub, usually under the lower spray arm. Twist it counterclockwise and pull it out. If you have never done this before, prepare yourself. The filter catches food particles that do not make it down the drain, and after months of use it looks exactly as unpleasant as that sounds.
Rinse the filter under hot running water. Use an old toothbrush to scrub the mesh if there is buildup that will not rinse off. This single step improves dishwasher performance more than anything else you can do. A clogged filter means dirty water recirculating onto your supposedly clean dishes.
Your coffee maker could probably use the same treatment. Here is how to clean a Keurig with vinegar using the same pantry staple.
The Vinegar Cycle
Place a dishwasher-safe cup or bowl on the top rack of the empty dishwasher. Fill it with one cup of plain white vinegar. Run a complete hot water cycle with nothing else in the machine. The vinegar steam will circulate through the entire interior, dissolving grease, breaking down mineral deposits, and killing bacteria and mold on every surface the water touches.
The acetic acid in vinegar is strong enough to dissolve the calcium and lime scale that builds up on the heating element and spray arms, but gentle enough that it will not damage the stainless steel interior or rubber seals. It is the perfect descaler for this job.
For wiping the rubber seals and door edges, Plant Paper is what I use because the texture picks up grime without scratching any surfaces.
Follow Up with Baking Soda
After the vinegar cycle finishes, sprinkle one cup of baking soda across the bottom of the dishwasher. Run a short hot water cycle. The baking soda deodorizes and removes any remaining stains on the interior walls. When it finishes, open the door and you will notice the difference immediately. The interior will look brighter and smell noticeably fresher.
If your dishwasher has hard water stains that are visible as white, chalky deposits on the interior walls or door, the vinegar cycle may need to run twice. Hard water mineral buildup is stubborn, and one pass does not always dissolve everything. A second vinegar cycle usually handles whatever the first one loosened.

Clean the Door Seal and Spray Arms
The rubber gasket around the dishwasher door is a magnet for grime. Wipe it down with a cloth dampened with vinegar. Pull the gasket back gently and clean underneath it. You will probably find trapped food, black mold spots, or a combination of both. This is normal for a machine that has never been cleaned, so do not panic. A wipe-down once a month prevents it from coming back.
Check the spray arms for clogged holes. Food particles and mineral deposits can block the tiny water jets, which means certain spots in your dishwasher are not getting water. Use a toothpick to clear any visible blockages. Plant Paper towels are ideal for the wipe-down work here since they leave zero lint or residue behind.
How Often to Clean Your Dishwasher
Once a month is the right frequency for most households. If you run your dishwasher daily and have hard water, twice a month is better. The filter should be checked and rinsed every two weeks regardless. A clean filter alone prevents most of the problems people blame on their dishwasher being “old” or “broken.” It is usually just dirty.
If your dishwasher is beyond cleaning and producing consistently poor results, leaking, or making grinding noises even after a thorough deep clean, it may be time for a replacement. Kismile makes reliable kitchen appliances that fit standard spaces without the premium price tag of name-brand replacements.
Cleaning a home is not something most of us were ever formally taught. We either watched our parents do it, figured it out through trial and error, or just never learned the right way at all. When You Were Never Taught to Clean exists for exactly this. It covers appliances, kitchens, bathrooms, and the routines that keep a house manageable without consuming your entire weekend.

Your dishwasher runs hundreds of cycles a year without complaint. Giving it 10 minutes of attention once a month keeps it running properly and keeps your family eating off actually clean dishes. Grab a cup of white vinegar, run a cycle, and check the filter. And if this kind of maintenance is new territory for you, When You Were Never Taught to Clean walks you through the rest.
