How To Clean Rust From Dishwasher

Is your dishwasher looking a little worse for wear, sporting unsightly rust stains? Don’t despair! Rust in your dishwasher is a common problem, but thankfully, it’s usually quite treatable. In this comprehensive guide, we’ll walk you through the steps to effectively clean rust from your dishwasher, prevent future occurrences, and keep your appliance sparkling clean. Let’s dive in!

Key Takeaways

• Identify the Source: Pinpoint where the rust is originating (often racks, spray arms, or the door).
• Gentle Cleaning First: Start with less abrasive methods like vinegar and baking soda.
• Rust Removers: If needed, use specialized rust removers, following the instructions carefully.
• Prevention is Key: Address chips in the racks and prevent standing water to avoid future rust.
• Regular Maintenance: Clean your dishwasher regularly to prevent buildup and rust formation.
• Consider Professional Help: For severe rust, especially if it’s affecting the dishwasher’s functionality, consider contacting a qualified appliance repair technician.

Understanding Rust Formation in Your Dishwasher

Before we tackle the cleaning process, let’s understand why rust appears in your dishwasher in the first place. Rust is a form of iron oxide, which forms when iron or steel is exposed to oxygen and moisture. Dishwashers, by their very nature, are humid environments, making them prime breeding grounds for rust. Several factors can contribute to rust development:

• Damaged Dishwasher Racks: The protective coating on dishwasher racks can chip or peel over time, exposing the metal underneath to water and detergent, leading to rust.
• Hard Water: Hard water contains minerals that can accelerate rust formation.
• Metal Utensils: Certain metal utensils can react with the dishwasher environment, contributing to rust.
• Standing Water: If water doesn’t drain properly, it can create a consistently damp environment, encouraging rust.
• Age of the Dishwasher: Older dishwashers may have more wear and tear on their components, making them more susceptible to rust.

Gathering Your Cleaning Supplies

Before you start cleaning, gather the necessary supplies. Having everything on hand will make the process smoother and more efficient. You’ll likely need:

• White Vinegar: A natural cleaner and mild acid that can dissolve rust.
• Baking Soda: A mild abrasive that can help scrub away rust.
• Dish Soap: For general cleaning and degreasing.
• Soft Cloths or Sponges: Avoid abrasive scrubbers that could damage the dishwasher.
• Old Toothbrush: For scrubbing hard-to-reach areas.
• Rust Remover (Optional): For stubborn rust, you may need a specialized rust remover. Choose a product specifically designed for dishwashers and follow the instructions carefully.
• Gloves: To protect your hands from harsh chemicals and rust.
• Safety Glasses (Optional): To protect your eyes when using rust removers.

Step-by-Step Guide: Cleaning Rust from Your Dishwasher

Now, let’s get down to the cleaning process. Follow these steps to effectively remove rust from your dishwasher:

1. Empty the Dishwasher: Remove all dishes, utensils, and racks from the dishwasher.
2. Inspect the Dishwasher: Carefully examine the dishwasher interior to identify all areas affected by rust. Pay close attention to the racks, spray arms, door, and bottom of the dishwasher.
3. Vinegar Soak: Place a dishwasher-safe bowl filled with one cup of white vinegar on the top rack of the empty dishwasher. Run the dishwasher on a hot water cycle. This will help loosen rust and remove other buildup.
4. Baking Soda Scrub: After the vinegar cycle, sprinkle baking soda over the rusted areas. Use a soft cloth or sponge to gently scrub the rust. For stubborn spots, use an old toothbrush.
5. Dish Soap Wash: Wash the dishwasher racks and interior with warm, soapy water to remove any remaining residue.
6. Rinse Thoroughly: Rinse the dishwasher racks and interior thoroughly with clean water.
7. Rust Remover (If Necessary): If the rust persists after the vinegar and baking soda treatment, use a specialized rust remover according to the product instructions. Be sure to wear gloves and safety glasses when using rust removers.
8. Dry Completely: After cleaning, dry the dishwasher interior and racks thoroughly with a clean cloth. This will help prevent future rust formation.

Cleaning Rust from Dishwasher Racks

Dishwasher racks are often the most susceptible to rust. If the racks have chipped or damaged coatings, consider repairing them with a dishwasher rack repair kit. These kits contain a coating that you can apply to the exposed metal to prevent further rust. Alternatively, you can replace the rusted racks altogether.

Dealing with Rust on Spray Arms

Rust can also accumulate on the dishwasher’s spray arms. Remove the spray arms and soak them in a solution of vinegar and water. Use an old toothbrush to scrub away any rust or debris. Make sure the spray arm holes are clear for proper water circulation.

Preventing Rust in Your Dishwasher: Proactive Measures

Once you’ve cleaned the rust from your dishwasher, it’s essential to take steps to prevent it from returning. Here are some preventative measures you can take:

• Repair Damaged Racks: As mentioned earlier, repair or replace damaged dishwasher racks.
• Use a Water Softener: If you have hard water, consider installing a water softener to reduce mineral buildup.
• Avoid Overloading the Dishwasher: Overloading can prevent proper water circulation, leading to standing water and rust formation.
• Run the Dishwasher Regularly: Running the dishwasher regularly helps prevent buildup and keeps the interior clean.
• Leave the Door Ajar After Use: Leaving the dishwasher door slightly ajar after each use allows moisture to escape, preventing rust.
• Regular Cleaning: Clean your dishwasher regularly with vinegar and baking soda to prevent rust buildup.
• Use Rinse Aid: Rinse aid helps water drain more efficiently, reducing the chance of standing water.

When to Call a Professional

In some cases, rust in your dishwasher may be a sign of a more serious problem. If you’ve tried the cleaning methods outlined above and the rust persists, or if you notice any of the following, it’s time to call a professional appliance repair technician:

• Extensive Rust Damage: If the rust is widespread and deeply ingrained, it may be beyond DIY repair.
• Dishwasher Malfunction: If the dishwasher is not functioning properly, the rust could be related to a mechanical issue.
• Unsure of the Source: If you can’t identify the source of the rust, a professional can diagnose the problem and recommend the appropriate solution.
• Rust Affecting Functionality: If rust is affecting the dishwasher’s ability to clean dishes properly, professional repair is necessary.

Frequently Asked Questions (FAQs)

Can I use steel wool to clean rust from my dishwasher?

No, avoid using steel wool or other abrasive scrubbers, as they can scratch the dishwasher’s interior and damage the protective coatings, potentially making the rust problem worse. Stick to soft cloths, sponges, or an old toothbrush.

Is it safe to use CLR in my dishwasher to remove rust?

While CLR (Calcium, Lime, Rust Remover) can be effective at removing rust, it’s crucial to check the product label to ensure it’s safe for use in dishwashers. Some CLR formulations may be too harsh and could damage the dishwasher’s components. Always follow the manufacturer’s instructions carefully.

How often should I clean my dishwasher to prevent rust?

It’s a good idea to clean your dishwasher at least once a month to prevent rust and other buildup. Regular cleaning will help keep your dishwasher running smoothly and extend its lifespan. A quick vinegar cycle every month can make a big difference.

Why is my brand new dishwasher already showing signs of rust?

Even new dishwashers can develop rust, especially if you have hard water or frequently wash items that have already started to rust. Make sure to address hard water issues and pre-wash heavily soiled items before loading them into the dishwasher. Also, inspect the racks for any manufacturing defects or damage.

By following these tips and techniques, you can effectively clean rust from your dishwasher and keep it sparkling clean for years to come. Remember, prevention is key, so take proactive measures to protect your appliance from rust formation. A little bit of regular maintenance can go a long way in preserving the life of your dishwasher.
