How to Clean Dishwasher with White Vinegar? | Empty-Rack Vinegar Method

For the full breakdown, see our best Clean Dishwasher Pods guide.

Cleaning a dishwasher with white vinegar works because the mild acid dissolves hard-water deposits, soap scum, and the greasy film that traps odors. Here is the exact process that appliance manufacturers and cleaning experts recommend.

What You Need Before You Start

You only need two things: distilled white vinegar and a dishwasher-safe container. A glass measuring cup, ceramic mug, or sturdy bowl all work, as long as it can sit upright on the rack without tipping over during the cycle.

• Distilled white vinegar — plain white vinegar works too; cleaning vinegar is stronger than the “eating” kind you keep in the pantry.
• A dishwasher-safe cup or bowl — anything that holds the vinegar upright on the top rack.

Step-by-Step: The Vinegar Cycle

Start with a completely empty dishwasher. This includes the silverware basket and any removable utensil holders, which can trap debris and block water flow.

1. Pull out the bottom rack and inspect the drain and filter area. Remove any food scraps, broken glass, or stray objects you find. Whirlpool’s guidance says to clean the filter before running a cleaning cycle.
2. Pour 1 cup of distilled white vinegar into your dishwasher-safe container. For a first deep clean on a very dirty machine, up to 2 cups is acceptable.
3. Set the container upright on the top rack in most guides, or the lower rack if you follow Whirlpool’s instructions. Keep it stable so it does not spill before the cycle starts.
4. Select the hottest cycle your machine offers — heavy, pots-and-pans, or the normal cycle on hot water all work.
5. Do not add detergent. Multiple sources are explicit that detergent cancels the cleaning effect of the vinegar.
6. Turn off the heated dry option if your machine has one. The heat can bake vinegar residue onto surfaces.
7. Run the full cycle, then open the door and let the interior air-dry. Wipe away any remaining spots with a soft cloth.

After the cycle finishes, the interior should look brighter and smell neutral. If your machine was especially dirty, you may need to wipe the door seal and detergent dispenser by hand with a vinegar-dampened cloth.

How Often Should You Do This?

Food Network recommends repeating the vinegar cycle no more than once a month. HGTV suggests running it every few weeks to keep odor and buildup in check. For a normal household that runs the dishwasher daily, monthly is plenty; every two weeks is fine if you notice a sour smell or white film on glasses.

Do not run vinegar through the dishwasher with dishes inside. The vinegar is meant for an empty machine, and it will not clean your tableware — it only cleans the appliance’s interior surfaces.

What About Baking Soda and Other Additions?

If lingering odor is a concern, a few drops of essential oil in the vinegar cup is a common home trick, but no manufacturer endorses it. Skip it if you have a sensitive nose or a machine with plastic interior parts.

One caution: vinegar is not safe for every dishwasher material. If your appliance manual warns against acids, follow the manual over this general advice. Similarly, at least one source recommends cleaning rubber door seals with soap and water rather than vinegar, because acid can degrade some seal compounds over time.

If your dishwasher still smells musty or leaves residue after a vinegar clean, the issue is usually trapped food in the filter or a clogged drain line — not the interior surfaces. Once you clear those, a clean cycle keeps the whole system fresh.

FAQs

Can I use apple cider vinegar instead of white vinegar?

Apple cider vinegar works in a pinch but can leave a brown tint on light-colored plastic interiors. Distilled white vinegar is the safer choice because it leaves no residue and costs less per cleaning cycle.

Will vinegar damage my dishwasher’s rubber seals?

Occasional use is fine, but routine vinegar exposure can dry out rubber gaskets over time. If you clean monthly, wipe the door seal with soap and water afterward and let it dry completely.

Why does my dishwasher smell worse after a vinegar rinse?

A stronger smell after cleaning usually means trapped food debris is still sitting in the filter or along the drain channel. Remove the filter, rinse it under hot water, and check the sump area for buildup before running another cycle.
