Clean your dishwasher monthly by clearing the filter, wiping the seals, and running a vinegar cycle followed by a baking soda cycle — never both at once.
A smelly or spotty dishwasher usually isn’t broken—it’s dirty. Store-bought cleaner or pantry staples, the process is the same.
Start With the Filter and Drain
The filter catches everything, so clean it first. Pull out the bottom rack. Consumer Reports notes many filters have a center cylinder that unscrews and disassembles; check your owner’s manual for exact steps. Rinse parts at the sink, using a sponge or old toothbrush on crevices, then reinstall securely.
Clear the drain area while the rack is out. Whirlpool recommends removing visible debris and wiping the drain before a maintenance cycle. Then inspect spray arms—if holes look clogged, rinse them and clear openings with a toothpick or skewer.
Wipe the Seals, Door, and Exterior
Food residue on the rubber door gasket is a major odor source. Wipe the gasket, door edges, hinge area, and control panel with a damp cloth and mild soapy water. For stainless steel, Consumer Reports recommends non-ammonia glass cleaner or a dedicated stainless cleaner, applied with the grain. Skip abrasive scrubbers—they scratch finishes and tear seals, shortening gasket life.
Run the Cleaning Cycle
The chemistry happens here.
- The vinegar cycle: Run a hot or normal cycle with no detergent and heat dry off.
- The baking soda cycle: Run a short hot cycle to deodorize and freshen.
Citric-acid-based cleaners work the same way; Consumer Reports recommends one monthly to break down limescale and hard-water film. Skip bleach unless your manual confirms your model’s materials can handle it. If you’re weighing upgrading instead of deep-cleaning, our top-rated dishwasher picks for cleaning performance cover the freshest models.
How Often Should You Do This?
Daily use or hard water? Lean toward monthly. Weekly control-panel and door wiping prevents grime buildup between deep cleans.
| Task | Frequency | Key Detail |
|---|---|---|
| Remove loose food bits | After each load | Keep drain area clear |
| Clean the filter system | Every 1–2 months | Unscrew center cylinder, rinse parts |
| Run a cleaning cycle | Monthly | Vinegar cycle, then baking soda cycle |
| Wipe door seals and gasket | Weekly or monthly | Mild soapy water, no abrasives |
Most odor and drainage issues trace back to a filter that wasn’t cleaned or wasn’t locked back into place—a loose reinstall lets food slip past. Skipped spray-arm holes change the spray pattern, leaving dishes wet.
FAQs
Can I mix vinegar and baking soda in the dishwasher?
No, never at the same time—they neutralize each other, canceling the cleaning power. Whirlpool explicitly says run separate cycles. Vinegar cuts grease and hard-water film; baking soda deodorizes.
Is bleach safe for cleaning a dishwasher?
Only if the owner’s manual says so. Bleach can damage some seals, gaskets, and stainless steel. Skip it if the manual is silent, and never mix with vinegar or acid. Stick with vinegar, baking soda, or citric-acid cleaner.
Why does my dishwasher smell even after cleaning the filter?
Check the door gasket, drain, and spray-arm holes—food hides in all three. Run the vinegar cycle to break down sump grease, then baking soda to neutralize odors. If it persists, inspect the drain line for a clog.
