Is your dishwasher leaving dishes less than sparkling? Over time, hidden grease, food particles, and mineral deposits can build up, making your dishwasher less effective. The good news is that a simple cleaning routine keeps your machine running smoothly and your dishes spotless.
This guide walks you step by step through how to clean a dishwasher, with clear instructions, practical tips, and trusted product recommendations.
Why Cleaning Your Dishwasher Matters
A dishwasher may look clean, but trapped food, soap scum, and hard water deposits can:
- Reduce cleaning power
- Cause odors
- Clog filters or spray arms
- Shorten the appliance’s lifespan
Regular cleaning prevents these issues and ensures sparkling results after every cycle.
Step-by-Step Guide: How to Clean a Dishwasher
Follow this simple routine for the best results:
1. Run a Hot Water Cycle
Start with an empty dishwasher and run a hot cycle. This loosens grease and food particles.
2. Remove and Clean the Filter
- Take out the filter from the bottom.
- Soak it in hot, soapy water for 10–15 minutes.
- Use a soft brush to scrub away debris.
- Rinse and reinstall.
3. Wipe the Door and Gasket
- Use a damp cloth with a vinegar solution.
- Pay special attention to rubber seals where grime collects.
- This prevents odors and ensures a tight seal.
4. Clear the Spray Arms
- Remove spray arms if possible.
- Use a toothpick or needle to clear any blocked holes.
- Rinse under warm water to restore proper water flow.
5. Clean Interior and Exterior Surfaces
- Wipe down walls and racks with a cloth dipped in warm, soapy water.
- For the exterior, use dish soap or stainless steel cleaner for a streak-free shine.
6. Optional: Vinegar and Baking Soda Cycle
- Place a cup of white vinegar on the top rack and run a hot cycle.
- Afterward, sprinkle baking soda across the bottom and run a short hot cycle.
- This combination deodorizes and removes mineral buildup.
