How to Clean Hard Water From Dishwasher

Hard water can leave unsightly stains and mineral buildup inside your dishwasher, affecting its performance and the cleanliness of your dishes. Over time, these deposits can clog components and reduce the efficiency of the appliance. Proper cleaning and maintenance are essential to ensure your dishwasher operates effectively and safely.

This guide on how to clean hard water from dishwasher will walk you through simple steps to remove hard water buildup and keep your dishwasher in top condition.

What is Hard Water?

Hard water contains high levels of minerals, such as calcium and magnesium. These minerals are naturally present in the ground, and when water flows through rocks and soil, it picks up these minerals. The more minerals water contains, the harder it is considered to be.

While hard water is not harmful to our health, it can cause problems with household appliances like dishwashers. The mineral deposits in hard water can create a film on dishes and glassware, leaving them looking cloudy or spotty even after washing. Hard water can also lead to clogs in dishwasher components, reducing its efficiency over time.

Needed Materials

To clean hard water from your dishwasher, you will need the following materials:

White Vinegar:

White vinegar is a natural cleaning agent that effectively breaks down mineral deposits and removes hard water stains. You can find it at most grocery stores.

Baking Soda:

Baking soda is another versatile household cleaner that can help remove hard water buildup and odors from your dishwasher.

Soft Cloth or Sponge:

To avoid scratching the interior of your dishwasher, use a soft cloth or sponge for cleaning.

Dishwasher-Safe Container:

You will need a container large enough to fit inside your dishwasher and hold the cleaning solution.

8 Step-by-step Guides on How to Clean Hard Water From Dishwasher

Step 1: Empty the Dishwasher 

Before you begin cleaning, make sure to remove all dishes, utensils, and any removable racks or components from the dishwasher. This step ensures that the cleaning process is thorough and that no items obstruct access to the interior surfaces of the appliance.

Once emptied, inspect the interior for any visible debris or food particles and remove them if necessary.

Step 2: Prepare the Cleaning Solution 

Fill a dishwasher-safe container with one cup of white vinegar. This natural cleaning agent will help dissolve the mineral deposits and hard water stains inside your dishwasher. Place the container on the top rack of the empty dishwasher, ensuring it is stable and won’t tip over during the cleaning cycle.

Do not dilute the vinegar with water, as full-strength vinegar is most effective for tackling tough buildup.

Step 3: Run a Hot Water Cycle 

Close the dishwasher and set it to run on the hottest water cycle available. The heat enhances the cleaning power of the vinegar by helping to break down mineral deposits more effectively. Allow the cycle to run its full course with only the container of vinegar inside. 

During this step, the vinegar will spread throughout the dishwasher, reaching all interior surfaces and dissolving hard water buildup and stains. Once the cycle is complete, open the dishwasher and carefully remove the container of vinegar.

Step 4: Sprinkle Baking Soda 

Sprinkle one cup of baking soda on the bottom of your empty dishwasher. The gentle abrasive properties of baking soda will help scrub and loosen any remaining mineral deposits that may have not been dissolved by the vinegar.

The baking soda will also help remove any lingering odors from the dishwasher.

Step 5: Run a Second Hot Water Cycle 

Close the dishwasher and set it to run another hot water cycle. This time, the baking soda will work with the hot water to further break down and remove hard water stains and buildup inside your dishwasher.

Once again, let the cycle run its full course before opening the dishwasher.

Step 6: Wipe Down Interior Surfaces

After completing two cleaning cycles with vinegar and baking soda, use a soft cloth or sponge to wipe down all interior surfaces of the dishwasher. Pay special attention to areas with significant mineral buildup, such as the door seal and bottom edges.

If necessary, you can also dip a toothbrush in the remaining vinegar solution and scrub any stubborn stains or deposits.

Step 7: Clean Removable Components 

Remove any detachable components from your dishwasher, such as racks and cutlery baskets. Soak them in a sink filled with hot water and one cup of white vinegar for 10-15 minutes. This will help break down any remaining mineral buildup on these parts before giving them a thorough scrub with a soft brush or sponge.

If there are any stubborn stains, you can also sprinkle baking soda on a damp cloth and gently scrub the affected areas before rinsing with warm water. Remember to dry all components thoroughly before placing them back in the dishwasher.

Step 8: Rinse and Run a Final Cycle 

After completing all the above steps, rinse all components and surfaces with hot water to remove any remaining vinegar or baking soda residue. Finally, run one last hot water cycle without any cleaning solution to fully flush out the dishwasher and ensure it is free of any buildup or odors.

Following these steps on how to clean hard water from dishwasher at least once a month can help keep your dishwasher in top condition and prevent hard water buildup. Additionally, you can also consider installing a water softener in your home to reduce the amount of minerals in your water and prevent future buildup in your dishwasher and other appliances. With regular maintenance, you can ensure your dishwasher runs efficiently and continues to provide you with clean dishes for years to come. Happy cleaning!

Tips to Prevent Hard Water Buildup in Your Dishwasher

• Use a water softener or filter to reduce the mineral content in your water supply.
• Run hot water through your dishwasher before starting a cycle. This helps remove any cold water and prevents minerals from settling on dishes during the wash.
• Use a rinse aid with each load of dishes to prevent spots or film caused by hard water.
• Regularly clean and maintain your dishwasher according to the manufacturer’s instructions, as this can help prevent buildup over time.

How Much Will It Cost? 

The cost of cleaning hard water buildup from your dishwasher depends on the supplies you already have at home. White vinegar and baking soda are inexpensive and widely available, with both items typically costing just a few dollars each. Soft cloths, sponges, or old toothbrushes for scrubbing are often household staples, so you may not need to purchase these separately. Overall, the cost of cleaning your dishwasher using this method is highly affordable, usually under $10 per cleaning session. 

If you choose to install a water softener to prevent hard water buildup in the future, the cost can vary widely. Smaller, point-of-use water softeners for appliances like dishwashers can cost between $50 and $150, while whole-house water softeners may range from $500 to $2,000 or more, depending on the system and installation fees. While this is a larger upfront investment, it can save you money in the long term by reducing hard water damage to your appliances.

Frequently Asked Questions
