How Long Does It Take to Clean a Dishwasher?

Quick Answer

Cleaning a dishwasher takes 30–60 minutes for a complete deep clean. Most of the active work takes 15–20 minutes, with the remainder spent running a cleaning cycle. Regular maintenance cleaning can be done in about 15 minutes, while neglected machines with heavy buildup may require up to 90 minutes.

Step-by-Step Cleaning Process

1. Remove and Clean the Filter (5–10 Minutes)

The filter is the most important component to clean and the most commonly neglected. Located on the dishwasher floor, it traps food particles and can develop odor-causing buildup. Twist or pull it out according to your model's instructions, then scrub it under warm running water with a soft brush and dish soap. For stubborn buildup, soak the filter in warm soapy water for 10 minutes.

2. Clean the Door Edges and Gasket (5 Minutes)

The rubber gasket around the door and the edges of the door panel don't get reached by the wash cycle. Use a damp cloth with a small amount of dish soap or a mixture of equal parts water and vinegar to wipe these areas. Pay special attention to the bottom edge of the door where grime collects. A toothbrush works well for reaching into gasket folds.

3. Inspect and Clean Spray Arms (5–10 Minutes)

Remove the spray arms (they usually unclip or unscrew) and check each nozzle for clogs. Food particles and mineral deposits can block the small holes, reducing cleaning performance. Use a toothpick or thin wire to clear each nozzle. Rinse the spray arms under running water before reinstalling.

4. Scrub Interior Walls and Racks (5–10 Minutes)

Wipe down the interior walls, ceiling, and around the drain area with a cloth dampened with vinegar solution. Check the drain for any debris or food buildup. Remove the racks and scrub any spots with rust or mineral deposits. A paste of baking soda and water works well on stubborn stains.

5. Run a Vinegar Cleaning Cycle (45–60 Minutes)

Place a cup of white vinegar in a dishwasher-safe container on the top rack and run a hot water cycle. The vinegar breaks down grease, dissolves mineral deposits, and eliminates odors. Do not add detergent during this cycle.

6. Run a Baking Soda Rinse (15–20 Minutes)

After the vinegar cycle, sprinkle one cup of baking soda across the bottom of the dishwasher and run a short hot water cycle. This deodorizes and removes any remaining stains.

Cleaning Frequency Guide

Task	Recommended Frequency
Clean the filter	Every 1–2 weeks
Wipe door edges and gasket	Every 2 weeks
Full deep clean (vinegar + baking soda)	Monthly
Inspect and clean spray arms	Every 1–3 months
Check and clear the drain	Monthly

When Your Dishwasher Needs Cleaning

Common signs include a musty or sour smell when the door is opened, a visible film or residue on dishes after a cycle, standing water at the bottom after a cycle completes, and reduced cleaning performance. Hard water areas may also notice white mineral deposits on the interior walls and racks, which require more frequent descaling.

Commercial Cleaners vs. DIY

Dishwasher cleaning tablets and commercial solutions like Affresh or Finish Dishwasher Cleaner work well but cost $3–8 per cleaning. White vinegar and baking soda deliver comparable results at a fraction of the cost. For heavy mineral buildup in hard water areas, citric acid (2 tablespoons in the detergent cup) is more effective than vinegar at dissolving calcium and lime deposits.
