To deep clean and maintain a dishwasher, regularly remove debris, clean filters, run a vinegar cycle, and wipe down seals and exterior surfaces.
A sparkling clean dishwasher means cleaner dishes and better appliance longevity. Follow this comprehensive guide to eliminate grease, limescale, and odors from your machine.
Essential Dishwasher Cleaning Supplies
Gather these items before starting:
- White vinegar
- Baking soda
- Old toothbrush or small brush
- Microfiber cloths
- Dish soap
- Rubber gloves
For tough jobs, consider antibacterial cleaning sprays or specialized dishwasher cleaning tablets.
Step-by-Step Deep Cleaning Process
1. Empty and Inspect Your Dishwasher
Remove all racks and utensils. Check for:
- Food debris in corners
- Broken glass pieces
- Paper labels or stickers
2. Clean Removable Parts
Filter Maintenance
Most modern dishwashers have removable filters. Consult your manual for removal instructions. Soak the filter in warm soapy water, then scrub with a toothbrush.
Spray Arm Care
Remove the spray arms and check for clogged holes. Use a toothpick to clear any blockages preventing water flow.
3. Scrub Problem Areas
Focus on these often-missed spots:
| Area | Cleaning Method |
|---|---|
| Door seals | Use vinegar solution and toothbrush |
| Dispenser | Remove and soak in warm water |
| Interior walls | Wipe with baking soda paste |
4. Run Cleaning Cycles
Perform these cycles in order:
- Vinegar Cycle: Place 2 cups white vinegar in a bowl on top rack. Run hottest cycle.
- Baking Soda Rinse: Sprinkle 1 cup baking soda in bottom. Run short cycle.
According to Maytag’s cleaning guide, this two-step process effectively removes buildup.
Maintenance Between Deep Cleans
Keep your dishwasher fresh with these habits:
- Wipe door seals weekly
- Use rinse aid to prevent spots
- Run garbage disposal before cycles
- Leave door slightly ajar after use
For regular cleaning, organic cleaning products offer gentle yet effective options.
When to Call a Professional
Seek help if you notice:
- Persistent standing water
- Loud grinding noises
- Error codes that won’t clear
- Visible rust or corrosion
As noted in The DIY Playbook, regular maintenance can prevent most major issues.
Special Considerations
Hard Water Areas
If you have mineral-rich water:
- Clean monthly instead of quarterly
- Use citric acid instead of vinegar
- Consider a water softener
Older Models
Vintage dishwashers may require:
- Special replacement parts
- Gentler cleaning methods
- More frequent maintenance
