Can You Put Vinegar in Your Dishwasher? What a Cleaner Actually Recommends
14.08.2026
Yes, you can run white vinegar through a dishwasher to cut mineral buildup and stale odors — but only occasionally, poured into a bowl on the top rack, never into the detergent cup or the bottom of the tub. Its acidity can degrade rubber door gaskets and hose seals over time, so most appliance makers and many pros suggest a purpose-made dishwasher cleaner instead.
What you'll need
- Plain distilled white vinegar (about 1 cup)
- A dishwasher-safe glass or ceramic bowl
- A microfiber cloth
- An old toothbrush for the edges and filter
- Baking soda (optional, for a second rinse)
- A commercial dishwasher cleaner, if your manual recommends one
Step by step
- Empty the dishwasher completely. Vinegar does nothing useful mixed in with a load of dishes.
- Pull out the bottom rack and lift out the filter (usually a twist-lock cylinder at the base). Rinse it under hot tap water and scrub the mesh with the toothbrush — trapped food is the real source of most odors.
- Wipe the rubber door gasket and the edges around the tub with a damp microfiber cloth. In a small NYC kitchen this seal collects grime fast because the unit sits inches from the stove.
- Pour 1 cup of white vinegar into a bowl and set it upright on the top rack.
- Run a normal hot cycle with the dishwasher otherwise empty. The vinegar disperses in the wash water and helps loosen the hard-water film that builds up on the interior.
- For a fresher smell, sprinkle a handful of baking soda across the bottom afterward and run a short rinse cycle. Do this as a separate step — don't combine vinegar and baking soda at once, since they cancel each other out.
- Leave the door cracked open to air out. That's hard if your unit is wedged under a counter with no clearance, so at least run the fan or open a window if you can.
What NOT to do
Don't pour vinegar into the detergent dispenser or the bottom of the tub before a load. Concentrated acid sitting against the door gasket and hoses is what wears out seals — the bowl-on-the-rack method dilutes it in the wash water. Don't use vinegar on a dishwasher with stainless-steel interior trim if the manual warns against acids; check first. Never mix vinegar with bleach or any chlorine-based cleaner — the combination releases a hazardous gas, which is genuinely dangerous in a tight, poorly ventilated apartment kitchen. And skip vinegar as a daily rinse aid; occasional use is the point, not a routine.
When to call a pro
DIY cleaning handles buildup and odors, but it won't fix standing water, a unit that won't drain, or a musty smell that returns within a day — those point to a clogged drain hose or pump that needs a technician, not more vinegar. And if you're moving out and the dishwasher is one line item on a long turnover checklist, or you simply don't have time to break down the filter, it's reasonable to hand the whole kitchen off. Book apartment cleaning with CleanWhale and we'll degrease the range, wipe the cabinets, and get the kitchen move-out ready.
FAQ
How often should I run vinegar through my dishwasher?
Once every one to two months is plenty for most apartment dishwashers. If your building has hard water — common across much of NYC — you might notice cloudy film sooner, but resist doing it weekly, since frequent acid exposure is what shortens the life of the rubber seals.
Is a store-bought dishwasher cleaner better than vinegar?
Often, yes. Purpose-made dishwasher cleaners are formulated to be gentler on gaskets and hoses than acetic acid, and many appliance manufacturers specifically recommend them over vinegar. Vinegar is cheap and handy in a pinch, but for a machine you want to last through your lease, a dedicated cleaner is the safer regular choice.
Can I use vinegar as a rinse aid in the dispenser?
It's not a good idea. The rinse-aid compartment feeds directly into seals and dispensing parts, so filling it with vinegar means constant acid contact with rubber. If you want spot-free dishes, use an actual rinse aid; save vinegar for the occasional bowl-on-the-rack cleaning run.
Why does my dishwasher still smell after cleaning?
A lingering smell usually means the filter or drain still holds trapped food, or water is sitting in the base. Pull and scrub the filter first. If the odor comes back within a day of a thorough clean, the drain hose or pump may be the culprit, and that's worth a technician's look.
