In this article, we’ll delve into the different materials used in grill mats and their safety, as well as provide step-by-step instructions for using and cleaning a grill mat.

By the end, you’ll have all the information you need to grill your favorite foods with a grill mat confidently. So let’s get started!

What Are Grill Mats Made of? Are They Safe?

Grill mats help to keep grills clean and prevent food from sticking. They are made from various materials, including fiberglass, PTFE, PFOA, copper, and silicone. Here’re their advantages and disadvantages:


Fiberglass is a popular material used in grill mats due to its durability and ability to withstand high temperatures. Fiberglass grill mats are usually coated with PTFE, which makes them non-stick and easy to clean.

However, according to MedicalNewsToday, exposure to its fibers can cause temporary irritation of the eyes, skin, lungs, and nose and stomach discomfort. Inhaling its long fibers can also result in severe lung injuries.

Although preliminary studies indicate the carcinogenic potential of glass fibers and glass wool in animals, the International Agency for Research on Cancer found no evidence that fiberglass exposure increases the risk of cancer in humans.


PTFE, or Teflon, is a synthetic polymer used as a non-stick coating for various kitchen utensils, including grill mats. PTFE grill mats are easy to clean and can withstand temperatures up to 500 degrees Fahrenheit.

However, PTFE can release toxic fumes when exposed to high temperatures. Inhaling these fumes can cause flu-like symptoms called “Polymer fume fever” or “Teflon Flu”. PTFE grill mats are safe to use as long as they are not overheated, and users should follow the manufacturer’s instructions for safe use.


Previously used in the production of PTFE, PFOA is a chemical substance associated with various health problems such as thyroid disorders, chronic kidney disease, and testicular cancer. It’s worth noting that PFOA is no longer used in the manufacturing of non-stick coatings in the US, including PTFE. Therefore, grill mats labeled as PFOA-free are generally considered safe for use.

Grill mats infused with copper are becoming popular due to the metal’s excellent heat-conducting properties. When used in grill mats, copper helps to distribute heat evenly, which results in perfectly grilled food.

It’s important to remember that copper is a heavy metal that can be toxic in large amounts. Thus, it is crucial to ensure that copper-infused grill mats are safe for food contact and to follow the manufacturer’s instructions for safe use.


Silicone is a popular material used in grill mats due to its safety and heat-resistant properties. It’s a safe material for food contact and does not contain harmful chemicals like PFOA or PFAS. Unlike most plastics, silicone has no melting point and remains solid until combustion occurs, making it a durable material for high-temperature cooking.

Silicone grill mats, such as the Cuisinart Silicone Grill mat, are commonly used to keep grill shelves clean and free from grease, stains, and scratches. Although silicone is heat-resistant, it is important not to place it directly on the grill. It may become brittle and lose its mechanical properties when exposed to high temperatures between 392 and 842°F (200-450°C).

While silicone grill mats may not offer the same level of non-stick performance as PTFE fiberglass mats, they are flexible, easy to clean, and a practical choice for many home cooks.

How to Safely Use a Grill Mat

Adding a grill mat to your BBQ setup can make grilling much easier and more versatile. However, to use a grill mat safely and effectively, there are a few guidelines to follow.

Firstly, make sure to thoroughly wash the mat before the first use and after each subsequent use. This will remove any dirt or residue that may have accumulated during storage or cooking. Simply use warm, soapy water and a sponge or cloth to clean the mat and rinse it well with water.

Next, place a mat over the grill grates, or use more next to each other for larger grates. If necessary, cut the mat to fit the grate. It would be best not to place grill mats on each other because they are non-stick and easy to slide.

To prevent the mat from melting or catching fire, avoid placing it directly on top of charcoal or exposed flames. It’s best to place the mat at least 5-7 inches away from the flames. This will also prevent any harmful fumes or chemicals from being released.

Once the mat is in place, apply food and cook as usual. The mat will help distribute heat evenly and prevent food from sticking to the grill. Be sure to monitor the food closely to prevent overcooking or burning.

After cooking, allow the mat to cool down before washing it. Use warm, soapy water and a sponge or cloth to clean the mat, and rinse it well with water. Dry the mat with a soft cloth and lay it flat when not in use to maximize its lifespan.

Tips for Safe Use

It’s important to use the appropriate tools to avoid damaging the nonstick surface of the mat. Avoid using metallic utensils with rough or sharp edges, as they can scratch or cut the mat. Instead, use nylon, silicone, or wooden utensils.

Avoid cutting food or using sharp utensils on the mat, which can damage the nonstick surface and reduce the mat’s lifespan. Use a cutting board instead and transfer the food onto the mat for grilling.

Prevent grease from pooling on the mat, as this can cause flare-ups and increase the risk of fire. Use a drip tray to catch any excess grease.

Keep in mind that PTFE starts to break down at temperatures around 260°C (500°F), and it decomposes at temperatures above 350°C (662°F). As a result, using a grill mat for searing is not recommended since searing requires temperatures higher than 450°F. Stick to regular grilling and avoid using the mat for searing to prolong its lifespan.

How to Clean and Maintain Your Grill Mat

Cleaning your grill mat is an essential step in maintaining its quality and lifespan. If you want your grill mat to perform well for years, you must take good care of it. Here are some tips on how to clean your grill mat effectively.

The first step in cleaning your grill mat is to let it cool down after use. Once it has cooled, soak the mat in hot soapy water for 5-10 minutes. This will help to loosen any grease or burnt-on food residue that may have accumulated on the mat during cooking.

After soaking, wipe the mat clean with a damp cloth or sponge. It’s crucial to avoid using any abrasive pads or cleaning agents, as they can scratch and damage the nonstick surface of the mat.

Most grill mats are dishwasher safe, so you can also clean the grill mat in the top rack of your dishwasher if you prefer. Simply place the mat in the dishwasher and run it on a gentle cycle with mild detergent. However, avoid using harsh detergents that can damage the mat.

When cleaning the grill mat, avoid using iron brushes or hard hair brushes. These can scratch the nonstick surface of the mat and reduce its effectiveness and lifespan. Instead, use a soft cloth or sponge to wipe the mat clean.

After cleaning, make sure to dry the mat thoroughly before storing it. Avoid folding the mat to store, as this can damage the nonstick surface. Instead, lay it flat in a cool, dry place until you’re ready to use it again.


To sum up, using a grill mat can be a convenient and effective way to enjoy outdoor grilling while minimizing mess and sticking.

However, keep safety in mind when using these mats. Always follow the manufacturer’s instructions and avoid using the mats at temperatures higher than recommended.

With appropriate maintenance, you can ensure that it lasts for many grilling seasons. So why not try one and see how it can improve your outdoor cooking experience?
