Hey there, fellow kitchen enthusiasts! Today, we’re diving into the fiery world of cast iron stove grates and their compatibility with that modern marvel known as the dishwasher. Ah, the dishwasher—a trusty sidekick in our battle against grease and grime. But should we proceed cautiously or hit the “Start” button without a second thought regarding cast iron? Let’s find out!
Why Should You Avoid Putting Cast Iron Cookware in the Dishwasher?
Before we embark on this soapy adventure, let’s take a moment to understand why cast iron cookware and dishwashers aren’t precisely the best of pals. Cast iron is a challenging and durable material, built to withstand intense heat and retain it for optimal cooking. However, exposure to a dishwasher’s merciless waters and high temperatures is not as forgiving.
Firstly, dishwashers are notorious for their aggressive cleaning agents, designed to tackle various culinary challenges. These potent detergents can strip away the special seasoning on your cast iron stove grates, leaving them vulnerable to Rust and diminished performance.
Secondly, the intense heat and constant moisture inside a dishwasher can accelerate the rusting process and cause damage to your precious cast iron companions. We certainly don’t want that, do we?

Now that we understand the pitfalls of dishwasher cleaning let’s explore some alternative methods to keep your cast iron stove grates looking spick and span. Don’t worry, my friends; we’ve got a few tricks up our sleeves!
1. Use a Degreaser
A trusty degreaser is your secret weapon when battling stubborn grease on your cast iron stove grates. These specialized cleaning agents are designed to break down and dissolve grease, making cleaning more manageable. Spray the degreaser on the grates, let it work for a few minutes, and then wipe away the oil with a clean cloth or sponge.
2. Employ the Power of Baking Soda and Vinegar
Ah, the dynamic duo of natural cleaning baking soda and vinegar! These household staples can work wonders in removing grease from your cast iron stove grates. Start by sprinkling a generous som of baking soda on the grates, focusing on the greasy areas. Then, pour vinegar over the baking soda, creating a foaming reaction that helps to lift and dissolve the grease. Let this magical concoction sit for a few minutes, then scrub the grime away with a brush or sponge. Rinse thoroughly, and voila! Your cast iron grates will be gleaming like new.
3. Harness the Power of Steam Cleaning
Did you know that Steam Can I Put Cast Iron Stove Grates in the Dishwasher? If you have a steam cleaner or access to one, it can be a fantastic tool for cleaning your cast iron stove grates. The high-temperature steam helps to loosen and remove stubborn grease, making your grates shiny and clean. Follow the instructions for your steam cleaner, directing the steam onto the grates and using a cloth or brush to wipe away the loosened grease. Just dry the grates thoroughly afterward to prevent any unwanted rust.
4. Embrace the Efficacy of Elbow Grease
Sometimes, good old-fashioned manual labor is the way to go. Grab a sturdy brush or sponge and roll up your sleeves because it’s time to give those cast iron stove grates some personal attention. Put a sink or basin with warm water and dish soap, and provide the grates soak for a few minutes to loosen any stuck-on grime. Then, scrub away the grease using your chosen cleaning tool, paying extra attention to the nooks and crannies. Rinse thoroughly and dry completely to protect from rusting.
How Dishwashers Damage Stove Grates
Now that we’ve explored some practical methods for removing grease, let’s delve into why dishwashers can wreak havoc on your cast iron stove grates.
- Harsh Detergents: Dishwasher detergents are formulated to tackle a wide range of dirty dishes, but their powerful cleaning agents can strip away the seasoning on your cast iron grates. This seasoning, a layer of baked-on oil or fat, provides a non-stick surface and helps protect the metal from rusting. You risk compromising their seasoning and overall performance by subjecting your grates to the aggressive chemicals in dishwasher detergents.
- Intense Heat: Dishwashers operate at high temperatures to ensure thorough cleaning and sanitization. Unfortunately, this heat can be detrimental to cast iron. Prolonged exposure to high temperatures can cause cast iron to warp or crack, leading to an uneven cooking surface and potential safety hazards. Moreover, the excessive heat can accelerate the oxidation process, causing Rust to develop on your once-pristine grates.
- Moisture Trapped in Cracks: Cast iron stove grates often have intricate designs and crevices, which can be difficult to dry completely. Dishwashers can trap moisture in these hard-to-reach areas with their closed and humid environment. This trapped moisture can promote rust formation, compromising the longevity and performance of your cast iron grates.
So, as you can see, the dishwasher’s harsh detergents, intense heat, and moisture-trapping environment can all conspire against your beloved cast iron stove grates. Keeping these culinary companions far away from the dishwasher’s domain is best.
How to fall Rust from a Cast Iron Stove Top Grate
Oops! Your cast iron stove grates seem to have fallen victim to that pesky enemy called Rust. But fret not! We have a few tricks to help you restore them to their former glory.
- Vinegar Soak: Prepare a mixture of white vinegar and water in a large container. Submerge the rusted grates in the vinegar solution and let them soak for a few hours or overnight. The vinegar’s acidity will help break down the Rust. After washing, scrub the grates with a brush or sponge to remove any remaining rust. Rinse thoroughly and dry completely.
- Baking Soda Paste: Create a thick paste by mixing baking soda with water. Apply the paste to the rusted areas of your grates and let it sit for a couple of hours. The baking soda’s gentle abrasiveness will help lift the Rust. Scrub the grates with some brush or sponge, rinse well, and dry thoroughly.
- Steel Wool: For more stubborn Rust, use steel wool to scrub gently outside the rusted spots. Make sure to use fine-grade steel wool to avoid scratching the surface of your grates. After removing the Rust, rinse the grates thoroughly, dry them completely, and apply a thin layer of oil to prevent future rusting.

Remember, prevention is critical to keeping Rust at bay. Regularly seasoning your cast iron stove grates and storing them in a dry place will help prevent Rust from forming in the first place.
Which Stove Top Grates Are Dishwasher Safe?
While we’ve established that cast iron stove grates and dishwashers aren’t the best match, some stove top grates can safely endure the dishwasher’s cleansing embrace. Typically, grates made of stainless steel or porcelain-coated cast iron are more dishwasher-friendly.
Stainless steel grates are known for their durability and resistance to Rust and corrosion. These grates can often withstand the dishwasher’s cleaning cycle without adverse effects. However, it’s still a good idea to check the manufacturer’s guidelines to ensure your specific stainless steel grates are dishwasher safe.
Porcelain-coated cast iron grates feature a protective layer of porcelain enamel, which enhances their non-stick properties and makes them easier to clean. Some of these grates may be labeled dishwasher safe, but verifying this information with the manufacturer before subjecting them to the dishwasher is crucial.
Remember, even if your stove top grates are deemed dishwasher safe, weighing the potential risks against the convenience is wise. Hand washing and proper maintenance can extend the life of your grates and ensure their continued performance.
Can I Wash Stove Top Burners in the Dishwasher?
Ah, the stovetop burners—the workhorses of our culinary adventures. While it’s tempting to toss them into the dishwasher for a thorough cleaning, it’s generally not recommended. Stove top burners, much like cast iron grates, can suffer from the dishwasher’s harsh detergents, high temperatures, and moisture-trapping environment.
Instead, opt for a more gentle approach to clean your stove top burners. Remove the burners from the stove and soak them in warm, soapy water for a few minutes. Then, use a brush or sponge to scrub away any grime. Rinse thoroughly, dry completely, and reassemble the burners. This manual cleaning method ensures longevity and optimal performance for your stove top burners.
Washing a Stove Top Grate with Soap and Water
Cleaning your stove top grates with a simple combination of soap and water can work wonders keeping them in pristine condition. Here’s how to do it:
- Prepare a Soapy Solution: Fill a sink or basin with hot water and add dish soap. Swish the water around to create a soapy solution.
- Submerge the Grates: Place the stove top grates into the soapy water, ensuring that they are fully submerged. Allow them to soak for some minutes to loosen any stuck-on debris.
- Scrub Away the Dirt: Using a brush or sponge, gently scrub the grates to remove grease, food particles, or residue. Pay extra attention to the corners and crevices where dirt tends to accumulate.
- Rinse Thoroughly: Once thoroughly scrubbing the grates, rinse them under running water to remove any soap residue. Make sure to rinse them well to ensure no soap remains, as it can affect the flavor of your future culinary creations.
- Dry Completely: After rinsing, pat the grates dry with a clean towel or allow them to air dry. It’s essential to ensure they are scorched to prevent Rust.
By washing your stovetop grates with soap and water, you can effectively remove surface dirt and keep them clean for your next cooking adventure.
1. Season the Stove Grates
Ah, seasoning—the secret to maintaining the performance and longevity of your cast iron stove grates. Seasoning involves creating a protective layer of oil on the surface of the grates, which helps prevent Rust and provides a natural non-stick coating. Here’s how to do it:
- Clean the Grates: Before seasoning, make sure the grates are clean and free from grease or debris. You can use the soap mentioned above and the water method or one of the earlier degreasing techniques.
- Dry Thoroughly: After cleaning, ensure the grates are completely dry. Use a towel or allow them to air dry to prevent moisture from affecting the seasoning process.
- Apply Oil: Using a paper towel or a clean cloth, apply a thin layer of oil to the entire surface of the grates, including the sides and corners. You may use oils with high smoke points, such as vegetables, canola, or flaxseed.
- Remove Excess Oil: After applying the oil, use a pure paper towel or cloth to remove excess fat. The grates should have a thin, even oil coating without any pooling or drips.
- Bake the Grates: Place the grates in an oven preheated to around 400°F (200°C). Let them bake for about an hour. This process helps the oil penetrate the cast iron pores, creating a durable seasoning.
- Repeat as Needed: For optimal results, you can repeat the seasoning process a few times, allowing the layers of oil to build up gradually. This will enhance the non-stick properties and rust resistance of your grates.
By seasoning your cast iron stove grates regularly, you’ll keep them in top-notch condition and enhance the flavors of your culinary creations.
Alternatives to Washing Stove Top Grates in the Dishwasher

- Vinegar and Baking Soda: Create an installation by mixing vinegar and baking soda. Apply the paste to the grates and let it sit for some time. The natural cleaning properties of vinegar and baking soda will help break down grease and grime. Scrub the grates with a brush, rinse well, and dry thoroughly.
- Citrus Power: Citrus fruits, such as lemons or oranges, can work wonders in cutting through grease. Cut a lemon or orange in half and rub the cut side over the grates. The acidity and natural oils in the citrus fruit will help remove dirt and leave a refreshing scent. Rinse well and dry thoroughly.
- Boiling Water and Dish Soap: For a deep clean, bring a big pot of water to a boil and add some dish soap. Carefully place the grates in the boiling water and let them simmer.
