How to Clean Your Dishwasher and Remove Smells
Complete guide to deep cleaning your dishwasher, eliminating odors, and maintaining optimal performance with vinegar, baking soda, and proper maintenance.
How To Clean Your Dishwasher And Remove Smells
A clean dishwasher is essential for properly sanitized dishes and a fresh-smelling kitchen. Over time, food particles, grease, and mineral deposits build up in your dishwasher, causing unpleasant odors and reducing cleaning performance. This guide provides a comprehensive cleaning routine to eliminate smells and restore your dishwasher to optimal condition.
Essential Materials
- White vinegar (2 cups)
- Baking soda (1 cup)
- Soft-bristle brush or old toothbrush
- Microfiber cloth
- Dish soap
- Optional: Commercial dishwasher cleaner
Step-by-Step Deep Cleaning Process
Step 1: Clean the Filter
Remove the bottom rack and locate the filter at the base of the dishwasher. Twist counterclockwise and pull up to remove it. Rinse under hot running water and scrub away debris with a soft brush. Food particles trapped here are the main cause of odors. Clean the filter weekly for best results.
Step 2: Wipe Down Door Gaskets and Edges
Dip a cloth in warm soapy water and thoroughly clean the rubber door seal, door edges, and around the detergent dispenser. These areas trap food residue and moisture, creating mold and mildew. Pay special attention to folds in the gasket where gunk accumulates.
Step 3: Run a Vinegar Cycle
Place a dishwasher-safe cup filled with 2 cups of white vinegar on the top rack. Run a complete hot water cycle without any dishes. The vinegar will break down grease, remove mineral deposits, and neutralize odors throughout the interior, spray arms, and drain.
Step 4: Deodorize with Baking Soda
Sprinkle 1 cup of baking soda across the bottom of the empty dishwasher. Run a short hot water cycle. Baking soda absorbs lingering odors and provides additional scrubbing action to remove stains from the interior walls.
Step 5: Clean Spray Arms
Remove spray arms by unscrewing or unclipping them. Check holes for blockages and clear with a toothpick or small wire. Rinse thoroughly under running water. Clogged spray arms reduce water pressure and cleaning effectiveness.
Common Mistakes to Avoid
- Using bleach in stainless steel dishwashers, which can cause discoloration and damage
- Neglecting to clean the filter regularly, allowing food buildup to create persistent odors
- Overloading the dishwasher, preventing water from reaching all surfaces
- Using too much detergent, which creates residue and encourages bacterial growth
- Leaving wet dishes inside for extended periods, promoting mold growth
Maintenance Tips to Prevent Odors
- Scrape plates before loading to minimize food particles entering the system
- Run hot water at the sink before starting the dishwasher to ensure immediate hot water flow
- Leave the door slightly ajar after cycles to allow air circulation and prevent moisture buildup
- Run a vinegar cycle monthly to prevent mineral deposit accumulation
- Check and clean the filter weekly, especially if you wash heavily soiled dishes
Frequently Asked Questions
Why does my dishwasher smell like rotten eggs?
This sulfur smell indicates bacteria feeding on trapped food particles in the filter, drain, or door gaskets. Clean the filter thoroughly and run a vinegar cycle. If the smell persists, check the drain hose for clogs or standing water.
How often should I deep clean my dishwasher?
Perform a complete deep clean monthly. Clean the filter weekly and wipe down door seals after each use if you notice food residue. Homes with hard water should run vinegar cycles more frequently to prevent mineral buildup.
Can I use lemon juice instead of vinegar?
Yes, lemon juice works similarly to vinegar for cutting grease and eliminating odors. Use 1-2 cups of fresh lemon juice in place of vinegar. However, vinegar is more effective at dissolving mineral deposits from hard water.
Final Thoughts
Regular dishwasher maintenance ensures clean dishes, eliminates odors, and extends the life of your appliance. Monthly deep cleaning with vinegar and baking soda, combined with weekly filter maintenance, keeps your dishwasher running efficiently and smelling fresh. Establish these simple habits to avoid costly repairs and replacement.
