When To Replace Your Grill Grates

Grill grates are an essential component of any outdoor gas or charcoal barbecue. They’re the only part of the grill that comes in contacts with the food. The quality and condition of your grill grates can significantly impact the flavor, texture, and overall enjoyment of your food. When they heat up, grates transfer heat to the food which helps develop grill marks. The grates can also effect the flavor of the food which is why keeping them clean is so important. Grill grates also play a critical role in the safety of your outdoor cooking. Dirty, rusty or damaged grates can harbor bacteria and cause food contamination. Knowing when and how to clean your grates can help extend the lifespan of your grill and improve your cooking. On average, you should replace grill grates every 5 to 10 years.

Grill grate need replacing at least once over the life of your grill on average. Cast-iron and steel grates can corrode over time or become rusty and porcelain tends to chip away or scratch.

Damaged grates can also contain bits of burned or dried food that are difficult to remove with a grill brush. This makes it harder to maintain the quality of your food being cooked on the grill.

What Are Grill Grates Made Of?

Grill grates are usually made out of stainless steel, cast iron, porcelain-coated steel, and porcelain-coated cast iron. A porcelain enamel coating on metal grill grates protects the underlying cast iron or steel from rust and/or decay.

  • The porcelain enamel coating comes in either a matte or glossy finish.
  • Most gas grills come with a porcelain enamel coating over their grates.
  • Charcoal grills comes with either raw metal or coated grates.
  • It’s rare to find raw metal grates on a gas grill.

Each material has its own pros vs cons and care requirements. But over time, they all become damaged, chipped, rusted or decayed and need replacement. On average, a grill needs new grates every 5 to 10 years. But this depends on a number of factors like the grate material, how often you use the grill and how you care and maintain the grates.

Signs That It’s Time To Replace Your Grill Grates

How long grill grates last varies depending on the type and quality of material they’re made of, how often you use them, the type of cooking, level of heat, and how well they’re cared for. With proper care and maintenance your grill grates will stay in good condition for years. But on average, a set of grill grates will need replacement every 5 to 10 years assuming you use the grill regularly.

There are three signs that will tell you when your grates need replacing:

Rust & Corrosion

All metal grill grates can eventually rust without regular cleaning. Rust can negatively effect the flavor of your food and become a health risk if metals flake off into your food.

Small amounts of surface rust can sometimes be sanded away with steel wool or a similar abrasive material like a wire brush or sandpaper. But deep rust that penetrates into the grate can’t be cleaned. If the rust doesn’t clean off easily and has penetrated into the metal, it’s time to replace your grill grates.

  • I highly recommend checking your grill grates regularly for signs of rust or corrosion
  • If the grates are heavily rusted or have large pieces of rust flaking off, it’s time to replace them.
  • The rust can transfer to your food and cause a metallic taste and may become a health risk if flakes end up in the food.
  • Corroded grates can become weaker and break apart during use which poses a safety hazard.

A small amount of surface rust can sometimes be cleaned with a nylon brush or some steel wool. But if your grill grates are covered in rust or the rust has penetrated deep into the metal, it’s time to replace them.

Worn Or Cracked Grates

Over time, the constant exposure to heat and moisture can cause grill grates to wear down and become brittle. These cracks can cause food to stick, leading to uneven cooking. It also makes cleaning more difficult because food gets stuck in the cracks.

If you don’t clean the grates properly, bacteria can grow which can possibly work its way into the food and make you sick. Chips from the grates can also become a health hazard if they flake off into the food.

If you notice cracks, chips, or deep grooves in the grates, it’s time to replace them.

Chips

Glossy porcelain-enameled steel and cast iron grill grates are especially susceptible to chipping. A chipped finish poses a health risk because chips may up in your food. It also creates an uneven cooking surface that makes it harder to grill and clean.

The porcelain coating on grill grates can chip when they’re banged or scrubbed too hard.

Chipped porcelain allows moisture to touch the metal which increases the likelihood of rust. This can taint the food and may also pose a health risk if rust gets into the food. Rust also weakens the metal which makes them wear out much faster.

If you notice your grate’s finish is starting to chip, it’s time to replace your grill grate.

Food Isn’t Cooking Evenly

If you notice that your food isn’t cooking evenly on the grates, it may be time to replace them. Old, worn grates can have an uneven surface area because of chips and general wear and tear. This can lead to hot spots and uneven cooking. If your food is burning in certain areas and not cooking in others, it’s time to invest in a new set of grates.

Difficulty Cleaning

If there are bits of food and built-up grime from fats and sauces that you can’t get off your grates, it’s a sign that your grates need replacing. Once the outer layer of protective coating wears off or starts to crack, the grates become much harder to clean. This can lead to uneven cooking, chips, rust and bacterial growth.

Once the grates start to chip and rust, it can become a health hazard if metal works its way into the food.

Difficulty cleaning is one of the first signs that your grates are starting to wear out.

  • Cleaning your grill grates is an important part of maintenance and helps them last longer.
  • If your food is sticking to the grates and difficult to remove, even after proper cleaning, it may be time to replace them.
  • Old, worn out grates can have rough or uneven surfaces that trap food particles. This makes cleaning harder to do.
  • Replacing the grates will make cleaning much easier and improve the overall taste of your food.
  • Difficulty cleaning the grates is an early sign that they’re starting to wear out.

How To Replace Grill Grates

Grill grates are very easy to replace. You simply lift the old set off and place the new ones onto your grill. Grates are designed to easily come off and on for cleaning. There’s no locking mechanism or clips to keep them in place.

The hardest part about replacing grill grates is finding the right size and material for your grill. I recommend buying a replacement grate from the grill’s manufacturer if they sell parts. I also like to use the same material grates if possible.

As long as you get the right size grate for your grill, it doesn’t matter who the manufacturer is. The most important thing is a good fit. But from my experience the manufacturer usually makes the best fitting grates for their grills.

Once the old grills are off, I usually clean the inside of the grill before I put on the new ones.

What Type Of Grill Grates Are Best?

What type of grill grates are best depends on how you like to grill and your personal preferences. Below we’ll go through the various options you’ll have to choose from which includes the grate material, size, price, maintenance, and durability.

What Are Grill Grates Made Of?

The material your grill grates are made of is the most important factor to consider. It effects everything from how the food cooks, maintenance, cleaning, durability and price. Each material has its own pros vs cons so choose a grate that best suits how you like to cook and your budget.

  • Cast Iron: Cast iron grates are known for their durability, heat retention, and the ability to produce a great sear on meat. However, they can be heavy and prone to rust if not properly maintained. They require more care and attention than stainless steel grates, but are the best for achieving a sear and deep grill marks.
  • Stainless Steel: Stainless steel grates are resistant to rust and corrosion, easy to clean, and offer good heat distribution. However, they can be more expensive and may not retain heat as well as cast iron. They have a long lifespan but can be hard to keep clean.
  • Porcelain-Coated Grates: Porcelain-coated grates are an affordable and lightweight option that’s easy to clean and maintain. However, the porcelain coating can wear off over time. This exposes the metal underneath to rust and corrosion. They have the shortest lifespan of any grill grate material. However they perform well and offer high heat for searing like cast iron with easy cleaning like stainless steel.
  • Ceramic: Ceramic grates are known for their heat retention and the ability to cook food evenly. However, they can be fragile and prone to cracks if subjected to rapid temperature changes.

Size

The size of your new grates is very important because they have to fit the grill. The new grates should fit properly without to much wiggle room. If the grates are the right size for your grill the fit should be snug so they don’t move around when you cook.

Price

High-quality grates can be expensive depending on the material and brand. Decide on a budget before you go shopping and consider factors such as durability, maintenance, and cooking performance when making your decision. If you only grill occasionally a mid priced grate may be a better option than something commercial grade.

Maintenance & Durability

Choose grates that are easy to clean and maintain. Consider the durability of the grates, based on factors such as the material they’re made of, coating, and thickness. The more durable the grates, the longer they’ll last and the better they’ll perform.

An easy way to tell well made grates from cheap one is the weight. In general, the heavier the metal the longer they’ll last. High end commercial grill grates are more than twice the weight of cheaper consumer grade grates. The metal is much thinner and so is the protective coating.

How To Maintain Grill Grates

The best way to maintain your grill grates is to clean them after every use. Scrape them with a brush and occasionally take the grates off and give them a wash.

Cleaning

Scrape off any food particles or debris using a grill brush or scraper. If the grates are still dirty, soak them in warm, soapy water for a few minutes, then scrub with a brush. Rinse the grates thoroughly with water and dry them completely before storing or placing them back on the grill.

Seasoning

Seasoning your grill grates can help protect them from rust and prevent food from sticking. To season cast iron grates, coat them with a light layer of cooking oil and heat them up on the grill for a few minutes. Repeat this process periodically to maintain the seasoning and ensure the grates remain in good condition.

Storing

Store your grill grates in a dry place to prevent rust and corrosion. If you live in a humid area, consider storing your grates in a sealed plastic bag to keep moisture out.

Protecting From The Elements

If you live in an area with harsh weather conditions, cover your grill grates when your not using them. This will help protect them from the elements and keep them in good condition for longer.

Is It OK To Grill On Rusted Grates?

No, you should not grill on rusted grill grates. First, the rust can flake off and mix with your food. This can add a metallic taste to the food and potentially cause health concerns if eaten. Second, the rust can create a rough surface on the grates which makes it harder to cook the food evenly. This can result in under-cooked or unevenly cooked food. Finally, grilling on rusted grates can cause them to deteriorate even faster. This leads to a shorter lifespan and the need for more frequent replacements.

Small amounts of surface rust can usually be cleaned off with a wire brush or steel wool. But it’s best to replace your grill grates if they’ve become heavily rusted.
