The dishwasher can be a lifesaver for those who don’t love scrubbing dishes. But you may not realize that dishwashers also need cleaning. Deep cleaning your dishwasher makes it work better and last longer. In the video above, Aaron Massey from House One demonstrates the best techniques for dishwasher cleaning so you can the most out of your appliance. We’ll provide step-by-step instructions and answers to frequently asked questions below.
Why Deep Clean Your Dishwasher?
Many homeowners overlook the importance of cleaning their dishwashers, assuming that the appliance cleans itself during regular cycles. However, neglecting this task can lead to several issues, such as the following:
- Bacterial and fungal growth
- Potential for expensive repairs
- Reduced cleaning efficiency
- Shortened appliance lifespan
- Unpleasant odors
How Often Should You Deep Clean Your Dishwasher?
Your deep cleaning schedule should be dictated by how often you use your dishwasher and your water hardness. But doing a thorough cleaning every two to three months is a good general rule. This helps prevent the buildup of mineral deposits, food particles, and detergent residue that can affect your dishwasher’s performance.
Materials Needed for Deep Cleaning Your Dishwasher
Before you begin the cleaning process, gather the following materials:
- Baking soda
- Cleaning vinegar
- Microfiber cloth or sponge
- Rubber gloves
- Small scrub brush
- Tupperware or dishwasher-safe container
Step-by-Step Guide to Deep Cleaning Your Dishwasher
Once you have your materials ready, it’s time to start the deep cleaning process. Here’s how to do it:
1. Remove and Clean the Bottom Rack
Remove the bottom rack of your dishwasher. This gives you easier access to the dishwasher’s interior and components. Inspect the rack for any signs of wear or damage. Give it a quick rinse if you notice debris or residue.
2. Clear Out Debris and Clean the Filter
Remove any visible food particles or debris before taking the filter out of the bottom of the dishwasher. Cleaning the filter is important, as it traps food particles and keeps them off the dishes being washed. Clean it in the sink using warm, soapy water. Rinse well before replacing it.
3. Clean the Spray Arms
The spray arms distribute water and detergent throughout the dishwasher. Over time, the holes in the spray arms can become clogged with food particles, grease, and mineral deposits. If possible, remove the spray arms and clean out any clogged holes using a toothpick or small brush. If they’re not removable, wipe them down with a damp cloth. This keeps them powerful and effective during wash cycles.
4. Wipe Down the Door Gasket
The door gasket, or seal, can accumulate grime and mildew over time. To clean this area thoroughly, use a rag or sponge soaked in distilled white vinegar. Pay attention to any folds or crevices where dirt might hide. A clean gasket creates a proper seal, which prevents leaks.
5. Run a Vinegar Cycle
Fill a dishwasher-safe container with 1–2 cups of white vinegar and place it on the top rack. Run an empty cycle using the hottest water setting. The vinegar will help dissolve mineral deposits, remove odors, clear away grease buildup, and sanitize the interior.
6. Follow Up With Baking Soda
After the vinegar cycle, sprinkle a cup of baking soda on the bottom of the dishwasher. Run a short, hot water cycle. The baking soda will help absorb lingering odors and provide a gentle scrubbing action to remove any remaining grime. After this final step, your dishwasher is fresh and ready for use.
7. Inspect and Clean Utensil Trays and Holders
Don’t forget to inspect and clean the utensil trays and holders. With tight spaces and holes, these areas can accumulate food particles and grime easily. Wash them in the sink with warm, soapy water. Make sure they’re dry before placing them back in the dishwasher.
8. Consider Using Bleach (Optional)
If your dishwasher still has stubborn stains or odors, consider running a cycle with bleach. (This step is not recommended for dishwashers with stainless steel interiors, as it can damage the finish.) Add 1/2–1 cup of bleach to the bottom of the dishwasher and run a full cycle. Never mix bleach with vinegar or other cleaning products. This step should be a last resort for the most persistent issues.
9. Clean the Dishwasher’s Exterior
While the dishwasher’s interior does most of the cleaning, don’t forget about the exterior. Wipe down the front and sides with a microfiber cloth and some mild detergent or a vinegar solution. This will remove fingerprints, smudges, and spills and keep it looking new.
Cleaning Your Dishwater Between Deep Cleans
Beyond deep cleaning, there are small steps you can take to keep your dishwasher looking and running well.
- Clean the filter weekly to prevent buildup
- Leave the dishwasher door open slightly after cycles to allow moisture to evaporate
- Run hot water in your sink before starting the dishwasher to start the cycle with hot water
- Scrape dishes before loading them to minimize food debris
- Use a rinse aid to prevent water spots and film on dishes
Troubleshooting Common Dishwasher Issues
Even with regular upkeep, you might still encounter problems every so often. Here are a few issues and their potential solutions:
- Not cleaning well: Check for clogged spray arms or a dirty filter. Also, make sure you’re not overloading the dishwasher, which can hinder good water circulation.
- Not draining well: Clear any clogs in the drain hose or garbage disposal. Sometimes running the garbage disposal before starting the dishwasher can help clear the drain path.
- Strange noises: Check for misplaced utensils or debris in the pump. Unusual sounds can also indicate issues with the motor or internal components, which might need professional attention.
- Unpleasant odors: Make sure there’s no trapped food in the filter or spray arms. Running a cleaning cycle with vinegar or baking soda can also help to freshen the interior.
- White film on dishes: This could be due to hard water. Try using a rinse aid or water softener. You might also need to adjust the amount of detergent you’re using.
If these simple fixes don’t solve the issue, it may be time to hire a professional appliance repair service. Regular professional check-ups can also catch potential issues early, preventing more serious problems down the line.
