Can I Put Grill Grates in the Dishwasher? A Comprehensive Guide to Cleaning Your Grill

 

Introduction

Speaking of cleaning your grill, one of the most frequent questions thrown at any gourmet, or even a regular backyard griller, is this: "Can I put my grill grates in the dishwasher?" You love grilling, but if you are like most of us grill owners, you would categorically state that cleaning those greasy food-encrusted grates is one of the least enjoyable parts of grilling. Obviously, a dishwasher would be an easy solution to this messy problem-but is it safe or effective?

Don’t settle for average grilling experiences any longer!

In this blog, we explore where grill grates belong-in the dishwasher or not-the associated risks, and other ways to get the job done to keep your grill in excellent condition. If you want to make maintaining your grill a whole lot easier, this guide will help you make the right decisions to keep your grill grates clean for your next barbecue.

The Short Answer: It Depends on the Material of Your Grill Grates

Generally speaking, the safety of putting your grill grates in the dishwasher largely depends on the material they are made of. Most grills take one of three possible material types: cast iron, stainless steel, and porcelain-coated steel, all three of which handle cleaning within a dishwasher differently. One should note that the main problem with running these kinds of grill grates through a dishwasher cycle is rusting or corrosion of the metal beneath the porcelain coating.

The grates made of cast iron are super durable and hold the heat really great, but they have a tendency to rust if not taken care of properly. One of the most important things when it comes to cast iron is the seasoning. It's this layer that goes over the grates, coating them in oil to keep out moisture and rust.

Why Cast Iron Shouldn't Go in the Dishwasher:

These are very harsh on the grates, and the hot water in dishwashers pulls the seasoning off of cast iron grates, leaving them unprotected and prone to rust. Cast iron is also highly reactive to water. When this happens-as it would in a dishwasher-rust occurs immediately. Alternative Cleaning Tip:

Clean cast iron grates after every use, using a stiff wire brush instead of the dishwasher. After cleaning, lightly coat them with vegetable oil or a dedicated cast iron seasoning oil for protection of the surface.

2. Stainless Steel Grill Grates: Sometimes Dishwasher-Safe

What's good with stainless steel grill grates, though, is that they won't rust or corrode as bad as their cast iron brethren, so they are just a little bit more forgiving when it comes down to cleaning. Some stainless steel grates can take the heat and pressure of water from a dishwasher needed to clean an item; but for most, if not all, of them, it's best to check how the manufacturer says to treat them.

Things to Consider:

While stainless steel grates can generally take a trip in the dishwasher, doing so repeatedly in those harsh detergents dulls the shine and eventually shortens its life.

The dishwasher might not remove that tough, baked-on grease, so a prescrub may be required.

Alternative Cleaning Tip:

For stainless steel grates, first remove food residue with a grill brush. Following this, soak the grates in warm water mixed with dish soap and soak them for about 15 to 20 minutes. Scrub with a sponge or a non-abrasive pad. Rinse well and dry thoroughly.

3. Porcelain-Coated Grill Grates: Handle with Care

Porcelain-coated grill grates are normally non-stick, and resistance to rust is among the positive features. In case of rough handling, the coating may chip or crack easily, leaving the metal underneath to rust.

Why the Dishwasher Isn't Ideal for Porcelain Grates:

These use high water pressure and harsh detergents that, with time and use, can also chip or wear down the porcelain coating.

Damaging it exposes the inner metal to rust and rusting processes.

Alternative Cleaning Tip:

Porcelain-coated grates are very susceptible to damage by wire brushes. For that, use a soft-bristled brush or nylon sponge. Any remaining stubborn stains, soak the grates in warm, soapy water. Scrub them clean with a soft stroke.

Pros and Cons of Putting Grill Grates in the Dishwasher

While the temptation to simply toss grill grates in the dishwasher for cleaning is rather high, there are some points to consider in favor of and against doing so.

Pros:

Convenience: The greatest positive aspect is that it gets the job done with the least effort from you. You can rest assured it saves effort and time, given that you would have scrubbed the grates by hand.

Effective for Certain Materials: Stainless steel grates turn out fairly clean if not too soiled and if dishwasher detergent is not too harsh.

Cons:

Risk of Damage: High water pressure and harsh detergents can scratch your grill grates, if they were coated or made from cast iron.

Incomplete Cleaning: The dishwasher does not catch the tough burnt-on foods and grease that builds up on grill grates, which means you would have to give them a good scrub once removed.

Rust Risk: Metals, such as cast iron, can rust or corrode over time due to exposure to water or detergents.

How to Clean Grill Grates 

If the grill grates are not dishwasher-safe or you prefer cleaning them more thoroughly, here are other methods to ensure your grill grates remain in the best condition possible.

1. Burn-Off Method

After grilling, allow the grill to remain on high for 10-15 more minutes, lid down, to burn the remainder of the food particles onto it. In this way, it is easier to brush the debris off. Allow the grill to cool a bit, and then take a wire brush or nylon grill brush to clean the grates.

2. Soak and Scrub

For deep cleaning, remove the grates from the grill and submerge them in soapy, warm water for about 20 to 30 minutes. Use a soft sponge, non-abrasive pad, or even a grill brush for scrubbing off grease and residues. The method will work just fine on both stainless steel and porcelain-coated grates.

3. Vinegar and Baking Soda Paste

Mix vinegar and baking soda into a paste for a natural, yet powerful cleaner. Apply this to grates, allow it to sit for 15 minutes, then scrub with either a brush or sponge. This is particularly great for tough baked-on grime.

4. Steam Cleaning

After cooking, place a wet towel laid over the grates while still warm, then close the lid. The steam will do all the work of loosening up stuck-on food and grease to wipe off much more easily after the grill has cooled down.

Pro Tip: The secret to keeping your grill grates in good condition is to do routine maintenance. Cleaning your grates every time you use them and occasionally doing a deeper clean will help them from building up over time.

Conclusion: Should You Put Grill Grates in the Dishwasher?

While it might be very tempting to put your grill grates in the dishwasher for a fast, easy clean, consider the material of your grates and the possible risks involved. Never put cast iron or porcelain-coated grates in the dishwasher, and while stainless steel grates may survive the cycle, they don't promise to come out perfectly clean. The effective cleaning of most grates is manual, by means of brushes, soapy water, and natural cleaners like vinegar and baking soda.

Taking the time to clean your grill grates properly saves your investment, but most importantly, the next time you want to cook out, you will not be dealing with all the leftover grease and grime. By cleaning it correctly, you will be able to keep your grill in its best condition and enjoy great food throughout the year.
