Keeping your dishwasher sparkling clean isn’t just about hygiene—it also ensures your dishes come out spotless every time. Over time, dishwashers can develop odors, buildup, and even mold, making it essential to learn how to clean a dishwasher effectively.
From simple DIY methods with baking soda and vinegar to deep cleaning techniques, maintaining your dishwasher doesn’t have to be complicated.
Dishwasher Cleaning Tips
According to cleaning experts, the best way to clean a dishwasher involves a combination of routine maintenance and occasional deep cleaning:
- Remove and clean the dishwasher filter – rinse under hot water to remove trapped food debris.
- Check spray arms and drain – unclog holes and clear any debris to ensure proper water flow.
- Use natural cleaners – run a cycle with white vinegar in a cup on the top rack, then sprinkle baking soda on the bottom and run a short hot cycle to remove stains and odors.
- Sanitize the door gasket and detergent dispenser – wipe down with a mixture of warm water and mild dish soap.
- Consider commercial cleaners – for limescale or heavy buildup, Affresh, Finish, or Cascade dishwasher cleaners can help restore performance.
Regular maintenance keeps your dishwasher efficient and prolongs its lifespan. Experts recommend a cleaning schedule at least once a month, with filter checks weekly.

I never realized how dirty my dishwasher was until I removed the filter. There was a mix of old food particles and grime. Cleaning it with warm water and a bit of dish soap made a huge difference!
I tried cleaning my dishwasher with vinegar and baking soda. I just sprinkled baking soda at the bottom and ran a hot vinegar cycle. Not only did it remove odors, but the inside also looks brand new.
I have a stainless steel dishwasher, and I was worried about scratches. Using a dishwasher-safe cleaner tablet worked perfectly without damaging the interior.
