Can You Wash Stove Top Grates in the Dishwasher?

Stove top grates often carry the brunt of cooking activities. From spillovers of soups and sauces to burnt-on food, these vital kitchen components require regular cleaning to maintain their aesthetic and functional values. However, with myriad cleaning options available, confusion can often arise on the most effective and safe methods.

Certain stove top grates, like those made of stainless steel or enamel-coated cast iron, can be washed in a dishwasher. Always verify with the manufacturer’s guidelines to avoid damaging your grates.

This guide will comprehensively discuss three distinct methods to clean stove top grates, including the feasibility of washing them in a dishwasher.

What Type of Stove Top Grates Can be Washed in the Dishwasher?

When it comes to cleaning stove top grates in a dishwasher, it’s important to consider the material the grates are made of. The following can be dishwashed.

Stainless Steel Grates: These are a common choice for many stovetops due to their high durability and resistance to heat. Stainless steel being a non-porous material doesn’t react or degrade when exposed to the water, heat, and detergents in a dishwasher.

It’s also resistant to rust, which is a common issue when metal kitchenware is repeatedly exposed to water. Consequently, stainless steel grates can generally be washed in a dishwasher without any significant risk of damage.

Enamel-Coated Cast Iron Grates: Cast iron grates are extremely durable and excellent at retaining heat, making them popular for high-performance cooking appliances. Whereas, unprotected cast iron can rust when exposed to water, which is why many cast iron grates are coated with a layer of enamel.

This enamel coating seals off the cast iron, protecting it from moisture and the risk of rust. It also provides a smooth, non-stick surface that’s easy to clean. Hence, enamel-coated cast iron grates are usually safe to clean in a dishwasher.

However, no matter what material your grates are made from, always refer to the manufacturer’s guidelines. Some manufacturers might have specific instructions or recommendations for cleaning, based on the design, construction, or specific materials used in their grates.

What Type of Stove Top Grates Cannot be Washed in the Dishwasher?

Certain types of stove top grates may not be suitable for dishwasher cleaning due to the nature of their materials and their reaction to prolonged exposure to heat and water.

Uncoated Cast Iron Grates: Uncoated or bare cast iron grates can rust when exposed to the moisture inside a dishwasher. Cast iron is porous, so when it is exposed to water intesity and heat of a dishwasher, it can oxidize, which results in rusting.

This not only impacts the appearance of the grates but can also degrade their functionality over time. Therefore, uncoated cast iron grates should generally be hand washed and dried immediately to prevent rust.

Brass Grates: Brass, an alloy of copper and zinc, can be susceptible to corrosion when exposed to the harsh detergents used in dishwashers. Over time, this can lead to a dulling of the brass’s shiny finish and potential structural damage. Brass grates are better suited for hand washing with a mild dish soap.

Porcelain Grates: Porcelain-coated grates are often found on gas stoves. While the porcelain coating makes these grates resistant to food sticking and easier to clean, it can also be susceptible to cracking or crazing (the formation of tiny cracks in the porcelain surface) when exposed to the high heat and water pressure of a dishwasher cycle.

Also, harsh dishwasher detergents can cause discoloration or dull the finish of porcelain grates. Therefore, it’s often recommended to clean porcelain grates by hand.

As always, it’s crucial to refer to the manufacturer’s instructions for your specific stove top grates. Each manufacturer may use different materials or coatings that could respond differently to dishwasher cleaning.

Cleaning Stove Top Grates Using Dishwashing Detergent

An effective and common way to clean stove top grates involves using dishwashing detergent. This method is simple yet efficient for removing dirt and food residue.

  1. Preparation: Begin by removing the grates from the stove top. Make sure they are cooled down and free from any cookware.
  2. Pre-Soak: Fill your sink or a large bucket with warm water. Add a few drops of dishwashing detergent to the water, then place the grates in the soapy water, ensuring they are fully submerged. Let them soak for at least 15 minutes.
  3. Scrubbing: Using a non-abrasive scrub brush, gently scrub the grates to dislodge and remove any stuck-on food particles or grease.
  4. Rinsing: Once cleaned, rinse the grates under running water to remove any soap residue.
  5. Drying: Dry the grates thoroughly using a clean, dry towel to prevent rusting.

Cleaning Stove Top Grates Using a Vinegar Solution

Vinegar is an excellent natural cleaner due to its acidic properties. This method is eco-friendly and cost-effective.

  1. Preparation: After removing the grates from the stove top, place them in a large container.
  2. Creating the Vinegar Solution: Mix equal parts of vinegar and water in the container, ensuring the grates are completely covered.
  3. Soaking: Allow the grates to soak in the vinegar solution for at least 30 minutes.
  4. Scrubbing: Scrub the grates gently with a brush, paying attention to heavily stained areas.
  5. Rinsing and Drying: Rinse thoroughly with clean water and dry with a towel.

Cleaning Stove Top Grates in the Dishwasher

The dishwasher is a great option for cleaning stove top grates, especially for dishwasher-safe types.

  1. Inspect Grates for Dishwasher Safety: Always check the manufacturer’s instructions before proceeding, as not all grates are dishwasher-safe.
  2. Prep the Dishwasher: Ensure the dishwasher is empty, apart from the grates.
  3. Positioning the Grates: Place the grates on the dishwasher’s top rack.
  4. Choosing the Cycle: Use a regular washing cycle for cleaning.
  5. Post-Washing: Once the cycle is finished, remove the grates and dry them completely.


Can you put stove top grates in the oven’s self clean cycle?

No, it’s generally not advisable to put stove top grates in the oven’s self-cleaning cycle. The extreme heat can warp or damage the grates.

Can washing stove top grates in the dishwasher damage the dishwasher?

No, generally washing stove top grates in the dishwasher does not damage the dishwasher itself. But, it’s crucial to ensure that the grates are securely placed to prevent them from dislodging and potentially causing harm during the wash cycle.
Also, large food residues should be removed before placing the grates in the dishwasher to avoid clogging the filter.

What is the best way to remove rust from stove top grates?

To remove rust, soak the grates in a solution of equal parts vinegar and water, then scrub with a brush. Rinse and dry thoroughly afterwards. Rust indicates lack of coating, so the grate should not go in the dishwasher.

Can you put stove top grates with food residue in the dishwasher?

Yes, but it’s best to remove large chunks of food before placing grates in the dishwasher to prevent clogging.

Can brass stove grates be washed in the dishwasher?

Brass stove grates should not be washed in the dishwasher, as the harsh detergents can damage the finish.

In Conclusion

Cleaning stove top grates is vital to prolong their durability and performance. Whether using dishwashing detergent, vinegar solution, or a dishwasher, understanding the method that suits your grates is key.

Always remember to check the manufacturer’s instructions for care and cleaning to maintain your stove top grates effectively.
