5 Steps to Remove Dishwasher Stains – A Guide from Comfort Appliance Service and Installation

Dishwashers are essential for making our daily lives easier, but over time, they can accumulate stains and mineral buildup that can affect their performance and the cleanliness of your dishes. If you’ve noticed unsightly stains inside your dishwasher or on your glassware, you’re not alone. Luckily, you don’t have to live with these stains! With a few simple steps, you can restore your dishwasher’s cleanliness and efficiency.

In this blog post from Comfort Appliance Service and Installation, we’ll guide you through 5 effective steps to remove dishwasher stains and keep your appliance running smoothly.

Why Do Dishwashers Get Stains?

Before we dive into the cleaning process, it’s important to understand why stains appear in the first place. There are a few common causes:

  • Hard Water Buildup: Hard water contains high levels of calcium and magnesium, which can leave behind mineral deposits on the interior of your dishwasher and your dishes.
  • Soap Scum: Over time, detergent can build up inside the dishwasher, creating cloudy spots on your glassware and staining the walls of the appliance.
  • Food Residue: Stubborn food particles, grease, or oils can build up on the interior of the dishwasher, leading to stains and unpleasant odors.
  • Rust and Corrosion: If your dishwasher’s racks or interior are made of metal, they may rust over time, leading to stains.

Now that we understand the causes, let’s go over the steps to remove those stains and restore your dishwasher’s shine!

Step 1: Clean the Dishwasher Filter

The first step in removing stains from your dishwasher is to clean the filter. Over time, the filter can trap food particles and debris, which can contribute to staining and unpleasant odors.

How to clean it:

  1. Open the bottom rack and remove the filter, which is usually located near the bottom of the appliance.
  2. Rinse the filter under warm water to remove loose debris.
  3. Use a soft brush or sponge to scrub the filter with a mixture of warm water and mild dish soap.
  4. Let it air dry before reinserting it back into the dishwasher.

Step 2: Run a Cleaning Cycle with White Vinegar

White vinegar is a natural, non-toxic cleaning agent that can break down mineral deposits, soap scum, and grime. Running a cycle with vinegar will help remove stains and deodorize your dishwasher.

How to do it:

  1. Place a cup of white vinegar in a dishwasher-safe container on the top rack.
  2. Run the dishwasher on a hot-water cycle (preferably without any dishes inside).
  3. The vinegar will help dissolve mineral deposits, soap scum, and other buildup, leaving your dishwasher cleaner and fresher.

For tough stains or mineral buildup, you may need to repeat this step once a month.

Step 3: Use Baking Soda to Deodorize and Remove Stubborn Stains

Baking soda is another powerful and natural cleaner that can remove odors and help lift stubborn stains from your dishwasher.

How to use it:

  1. After running the vinegar cycle, sprinkle about 1 cup of baking soda directly into the bottom of the dishwasher.
  2. Run a short, hot water cycle (again, with no dishes inside). The baking soda will scrub away stains and leave your dishwasher smelling fresh.

Baking soda is especially effective for removing water spots and stains that appear on the walls of the dishwasher or on your glassware.

Step 4: Clean the Spray Arms and Nozzles

Over time, mineral deposits or food particles can clog the spray arms and nozzles, affecting water flow and potentially leaving stains on your dishes. Cleaning these parts is essential to maintaining your dishwasher’s performance.

How to clean them:

  1. Remove the spray arms (usually by unscrewing them or pulling them off).
  2. Inspect the holes in the spray arms for any blockages, and use a toothpick or small brush to dislodge any debris.
  3. Rinse the spray arms thoroughly under warm water to remove any buildup.
  4. Reinstall the spray arms once they’re clean and dry.

Step 5: Check the Drain for Clogs

If your dishwasher has a slow drain or you’re seeing persistent stains, there may be a clog in the drain. Food particles, grease, or even mineral buildup can clog the drain, preventing proper water flow and causing stains.

How to clear the drain:

  1. Turn off the dishwasher and remove the bottom rack.
  2. Check the drain for visible obstructions or debris.
  3. If there’s debris stuck in the drain, remove it by hand or with a small tool like a pair of pliers.
  4. Run a cycle with hot water to ensure that the drain is clear and the water is draining properly.

Bonus Tip: Use a Dishwasher Cleaner

For regular maintenance, you may want to use a dishwasher cleaner once every few months. These commercial cleaning products are formulated to remove grease, mineral buildup, and food particles. Simply follow the instructions on the label, and use the cleaner in place of vinegar during a cleaning cycle.

How to Prevent Stains from Returning

Now that you’ve cleaned your dishwasher, here are some tips to help prevent stains from building up again:

  • Use the Right Detergent: If you have hard water, opt for a dishwasher detergent designed to combat mineral buildup. Some detergents come with added rinse aids that can help prevent water spots and stains.
  • Dry Your Dishes: If you notice spots forming on your dishes after the cycle, try drying them manually with a soft cloth. This can help prevent water spots and mineral deposits from settling.
  • Use a Rinse Aid: Rinse aids help to prevent water spots and reduce hard water buildup on both your dishes and the dishwasher’s interior.
  • Regular Maintenance: Clean your dishwasher filter, spray arms, and drain regularly to keep everything in working order.

When to Call a Professional

If you’ve followed all these steps and your dishwasher still has persistent stains, or if it’s not cleaning properly, it could indicate an issue that requires professional attention. Problems like a malfunctioning water pump, a faulty heating element, or a more serious clog could be the culprit.
