Is your dishwasher leaving cloudy glasses, greasy film, or a funky odor behind? Knowing how to clean a dishwasher with vinegar can fix all three in about an hour, using something you already have in your kitchen. White vinegar breaks down grease, dissolves mineral deposits, and helps loosen the residue that causes a stubborn dishwasher smell.
Why Clean Your Dishwasher Regularly?
Even though it washes dishes, your dishwasher collects food particles, soap scum, and hard water deposits over time. That buildup can clog spray arms, slow drainage, and leave smelly residue on your plates. A monthly cleaning keeps everything running smoothly and helps your appliance last longer.
What You’ll Need
- 2 cups of distilled white vinegar
- 1 cup of baking soda
- A dishwasher-safe cup or bowl
- A soft brush or old toothbrush
- A microfiber cloth
Step 1: Empty the Dishwasher and Remove Debris
Take out all dishes and racks, then check the bottom for food scraps, labels, or broken glass. Wipe away any visible gunk before you start.
Step 2: Clean the Filter
A dirty filter is a common cause of bad odors and poor cleaning. If you’re wondering how to remove the dishwasher filter, it’s usually a twist-and-lift cylinder or a flat mesh screen at the bottom of the tub. Check your manual for the exact type. Once it’s out, rinse it under warm water and scrub it with a soft brush and a little dish soap. Regularly learning how to clean your dishwasher filter is the easiest way to prevent clogs and smells.
Step 3: Run a Vinegar Cycle
Here is how to clean a dishwasher with vinegar in its simplest form:
- Place a dishwasher-safe cup filled with 2 cups of white vinegar on the top rack.
- Make sure the dishwasher is completely empty.
- Run a hot water cycle on the longest, hottest setting.
The hot water and vinegar work together to dissolve grease, soap scum, and limescale from the walls, spray arms, and drain area.
Step 4 (Optional): Deodorize with Baking Soda
If odors linger after the vinegar cycle, sprinkle 1 cup of baking soda across the bottom of the tub and run a short hot cycle. The baking soda freshens the interior and lifts any leftover residue. This two-step vinegar and baking soda method is popular because it’s cheap and free of harsh chemicals, but you can skip the second step if your dishwasher already smells fresh.
Never mix vinegar with bleach or pour them in at the same time, because the combination creates toxic fumes.
Step 5: Wipe the Door, Gasket, and Edges
Dip a cloth in a vinegar and water mix and wipe the rubber gasket, door edges, and control panel. These spots trap moisture and grime that a regular cycle can’t reach.
Alternative: Citric Acid for Hard Water
If you have heavy limescale or cloudy glassware, citric acid to clean a dishwasher is a great alternative. Put a couple of tablespoons in the detergent compartment and run a hot cycle. It’s especially useful in areas with hard water.
Brand-Specific Notes
The steps for how to clean a dishwasher with vinegar are nearly the same across brands, whether Samsung, Bosch, or Kenmore. If you’re looking for how to clean a Samsung dishwasher, you can use the steps above but check the manual first. Some brands recommend their own cleaning tablets, and a few caution against frequent vinegar use because it can wear down rubber seals over time. Manufacturers differ, so check your manual before using vinegar, especially if your dishwasher has a stainless-steel interior or rubber seals and gaskets.
Tips to Keep Your Dishwasher Fresh
- Scrape plates, don’t pre-rinse. Remove large food bits, but let your finish dishwasher pods or Cascade dishwasher detergent do the cleaning work.
- Use rinse aid. If you’re asking what is dishwasher rinse aid, it’s a liquid that helps water sheet off dishes so they dry spot-free and prevents mineral film.
- Keep a simple routine. A clean dishwasher vinegar cycle between deeper cleanings is an easy way to keep buildup under control, as long as your manual allows it.
- Leave the door slightly open after a cycle so moisture can escape.
- Clean the filter every month to stop odors before they start.
When Vinegar Isn’t Enough
If you’ve followed how to clean a dishwasher with vinegar and you still notice standing water or a lingering odor, the problem may be your drainage. Check that the dishwasher drain hose loop (a high loop in the hose under your sink) is installed correctly, because a poorly placed hose lets dirty sink water flow back into the machine. If water isn’t draining at all, you may need to learn how to manually drain a dishwasher by removing the filter and bailing out standing water with a cup and sponge.
If none of that helps, or the machine is making unusual noises or leaking, it’s time to call professional dishwasher repair services rather than risk a bigger problem.

How often should I clean my dishwasher with vinegar?
Once a month is enough for most households. If you have hard water or run the dishwasher daily, you may want to do it more often.
