Can You Put Stove Grates In The Dishwasher?

As you prepare delicious meals in your kitchen, stove grates bear the brunt of spills, grease, and food residue. Cleaning them thoroughly can be a daunting task. You may wonder if the dishwasher is a suitable option for tackling this challenge. Can you confidently place stove grates in the dishwasher?

Certainly, stove grates can be placed in a dishwasher for cleaning, as this method can prove quite efficient. However, it’s crucial to consider the dishwasher safety of different grate types and heed the manufacturer’s instructions and recommendations to avoid damage.

In this article, I explore the pros and cons of dishwasher cleaning for stove grates, share tips on ensuring safety and effectiveness, and offer alternative cleaning methods for those who prefer different approaches. Let’s dive in!

Understanding Stove Grates

Recognizing the nature and composition of stove grates is fundamental to their proper upkeep. Stove grates are often made of cast iron or may feature an enamel coating and understanding these differences can help when it comes to cleaning.

Cast Iron Stove Grates

Cast iron is a dense, sturdy substance with excellent heat retention properties, making it ideal for use in the oven or on the stovetop. Due to their strong and durable structure, cast iron grates generally last longer, but require regular maintenance to prevent rust.

Enamel Coated Grates

These are essentially iron grates coated with enamel. They represent a more stylized choice, offering a glossy, high-end look, and being comparatively easier to clean. The enamel layer protects the underlying iron from moisture, preventing rust. However, they might chip or crack if roughly handled or dropped, revealing the metal beneath, which can then rust.

Putting Stove Grates in the Dishwasher: Pros and Cons

Using a dishwasher for cleaning stove grates provides certain perks, but it also carries the risk of potential damage. Let’s delve into the upsides and downsides:


  • Convenient: One of the key benefits of using a dishwasher to clean stove grates is its convenience. Just put the grates in and let the machine do the hard work for you.
  • Time-saving: Trying to clean grates manually can be very time-consuming. In contrast, using a dishwasher allows you to spend time on other tasks, making it a time-effective method.


  • Damage risk: Although dishwashers can clean grates efficiently, they potentially pose a significant risk to grates, especially those enamel-coated ones. High temperature and detergent can cause the enamel coating to chip or crack.
  • Decreased longevity: Even cast iron grates may not be safe from the harsh environment of a dishwasher. Over time, the abrasive nature of the dishwasher might gradually cause the grates to deteriorate, reducing their longevity.

Dishwasher Safety of Different Grate Types

Knowing the dishwasher safety of your stove grates is crucial, as it helps you choose the best cleaning method, especially when it comes to cast iron and enamel-coated grates.

Cast Iron Grates

While cast iron grates are incredibly durable, they are typically not safe to put in the dishwasher. The drawback is that the high temperatures and detergents can strip their protective oil layer, leaving them susceptible to rust.

Enamel-Coated Grates

Relative to cast iron grates, enamel-coated ones seem more dishwasher-friendly since the enamel coating protects against rust. However, it’s important to note that high temperatures and harsh detergents may cause this coating to chip or crack, exposing the cast iron base to damaging elements.

Alternatives to Dishwasher Cleaning

If you prefer or need to avoid dishwasher cleaning, there are several effective alternatives for cleaning stove grates by hand.

  • For routine cleaning, you only need warm, soapy water and a gentle scrubbing brush. After removing any loose food particles, soak the grates in warm soapy water for a while and then scrub away any residue.
  • To combat grease, a DIY paste of baking soda and water can also help. Apply it and leave it on for about 20 minutes, then scrub away.
  • To remove rust from cast iron grates, a mixture of vinegar and water can be handy. Spraying this solution on the rusty areas and then scrubbing gently with a brush should help dissolve the rust.

Remember, no matter which method you use, dry your grates completely after cleaning to prevent rust formation. Also, it can help to occasionally season cast iron grates with cooking oil to restore their protective layer after cleaning. So, even without a dishwasher, there are efficient ways to keep your stove grates clean and in good condition.

Dealing with Stubborn Grime

Sometimes, stubborn grime can resist initial cleaning attempts, requiring heavy-duty cleaning solutions. Here are some methods of using everyday household items like baking soda, vinegar, and ammonia.

  1. Baking Soda: Having strong cleaning properties, baking soda can handle tough dirt and grime. Make a paste with water, apply it to the grates, let it sit for 20 minutes or so, then scrub with a non-abrasive brush or cloth. Rinse thoroughly and pat dry.
  2. Vinegar: With its acidity, vinegar is excellent for breaking down hard-to-remove grime. Spray a solution of equal parts vinegar and water onto the grates, let it stand for 15 minutes, then scrub clean.
  3. Ammonia: For the hardest grime, ammonia can be a last resort. However, ensure adequate air circulation, protect your skin and eyes, and never combine it with other chemicals, especially bleach, as it can produce toxic fumes. Put the grates in a sealable bag with a small amount of ammonia, seal it, and let them sit overnight. Remove carefully and rinse thoroughly in the morning.

Grate Maintenance Tips

Keeping your stove grates in top shape goes beyond just knowing how to clean them. Regular maintenance and adopting certain preventative measures can help ward off stubborn grime and keep your grates clean for longer.

  • Regular Cleaning. Don’t let dirt and grime build up. Regularly wipe down your grates with a damp cloth and some mild dish soap after use.
  • Spill Management. Spills happen, and the quicker you deal with them, the easier they are to clean. Once the grates are cooled, wipe up spills as soon as possible to prevent them from getting baked on.
  • Preventive Measures. Consider using grate covers designed to catch spills and drips, making cleanup easier. Moreover, avoid sliding pots and pans over the grates to prevent scratching their surface.

Risks of Dishwasher Cleaning’

While the idea of popping your grates into the dishwasher for a hands-free clean may sound appealing, it’s worth diving a bit deeper into some of the risks and potential damage that could result from this method.

Stripping of Protective Layer

This is particularly true for cast iron grates. The high temperatures and harsh detergents used in dishwashers can strip away the oil layer that protects against rust.

Enamel Damage

Enamel-coated grates also face risk from dishwasher cleaning. Frequent exposure to aggressive cleaning can lead to chipping or cracking of the enamel.

Rust Formation

Once stripped of protective layers or coatings, both cast iron and enamel-coated grates are more susceptible to rust, especially if not thoroughly dried after cleaning.

Manufacturer’s Instructions and Recommendations

The last resort in maintaining and cleaning your stove grates should be the instructions provided by the manufacturer. These guidelines cater to the specific build and materials of your grates, offering personalized advice.

Understanding Instructions

Manufacturer’s guidelines typically provide explicit cleaning and maintenance instructions for your grates. These instructions can greatly influence the longevity and performance of your grates, as they take into consideration the materials and design of the product.

Safety Measures

The manufacturer’s safety guidelines can also point out any specific precautions you need to take. This information is vital, especially when using aggressive cleaning agents or when your grates are composed of different materials that may react differently to cleaning methods.


In conclusion, cleaning and maintaining stove grates may require more thought than simply placing them in a dishwasher. Your stove grates, whether they’re made of cast iron or have an enamel coating, each requires its own level of care. While dishwashers offer a convenient solution, they also carry risks including stripping protective layers and causing potential damage. Taking a mindful approach to cleaning your stove grates will guarantee not just a gleaming kitchen, but a long-lasting appliance ready to handle any culinary adventure.
