Do Grills Rust?

When it comes to grills, there’s one big question on everyone’s mind: do they rust? The answer is…it depends. Grills can rust if they’re not properly taken care of, but with little maintenance, your grill can last for years. In this blog post, we’ll take a closer look at why grills rust and how you can prevent them from happening. We’ll also provide tips for cleaning and maintaining your grill to stay in good condition. So, whether you’re a new griller or an experienced pro, read on for all the information you need to keep your grill rust-free!

Do Grills Rust?

Reasons Why Grills Rust

The Material Used

Most barbeque grills are made of steel, which is an iron alloy. Steel is a popular grill material because it’s durable and relatively inexpensive.

However, one downside of steel is that it tends to rust over time. Rust results from iron oxidation, which occurs when iron comes into contact with water or moisture.

Oxygen from the air reacts with the iron to form iron oxide, which is why rust is often red or brown in color.

While there are some ways to prevent rusting, such as applying a coat of paint or sealant, eventually, all grills will succumb to the elements.

For this reason, many people prefer to buy grills made of stainless steel, which is more resistant to rusting. Stainless steel is an alloy that contains chromium, which forms a protective layer on the metal’s surface and helps prevent corrosion.

While stainless steel grills are more expensive than their steel counterparts, they require less maintenance and will last longer.

Food Residues

If you’ve ever cleaned a grill, you know that food residues can be tough to remove. Not only do they cause the grill to look dirty, but they can also lead to rusting. So why do grills rust?

When grill plates are heated, the fats and oils in food residues begin to break down. The resulting mixture of fat and water creates an ideal environment for rust to form.

In addition, the grill’s high heat causes any water in the residue to evaporate, leaving behind a concentrated layer of fat. As the fat cools, it hardens and forms a bond with the metal surface of the grill.

This process is accelerated by repeated heating and cooling, which is why grill plates often show signs of rust after just a few uses.

To avoid this problem, cleaning your grill regularly and removing all food residues before they can harden is important.


Moisture in the air is the biggest culprit for rusting grills. When the air is humid, it causes moisture to condense on the surface of the grill.

This moisture then reacts with the iron in the grill, causing it to rust. The best way to prevent your grill from rusting is to keep it covered when you’re not using it.

This will protect it from the elements and help to keep moisture levels down. You should also take care to dry your grill off after each use, as this will help to prevent moisture buildup.

With a little care and attention, you can keep your grill looking brand new for years to come.

Salty Water

Salty water is one of the most common causes of rust on grills. When salt water evaporates, it leaves behind mineral deposits that can corrode metal.

In addition, salt water is often used to clean grills, and if the grill is not properly rinsed after cleaning, the salt water can also cause rust.

In addition, grills that are stored near the ocean are also at risk for rusting due to the high concentrations of salt in the air.

To prevent rust, cleaning and drying your grill after each use is important as storing it in a dry, protected area.

Ways to Keep Your Grill from Rusting

Clean It Regularly

One of the best ways to keep your grill from rusting is to clean it regularly. After each use, be sure to scrub the grate with a wire brush to remove any food or grease buildup.

You should also give the rest of the grill a good cleaning every few weeks. This will help to remove any accumulated dirt and grime.

When cleaning, be sure to use mild soap and avoid harsh chemicals, as these can damage the finish on your grill. In addition, it is important to ensure that your grill is completely dry before storing it.

If you live in an area with high humidity, you may need to take additional steps to prevent rusting, such as applying a coat of paint or oil to the metal surface. These simple precautions allow you to keep your grill in good condition for many years to come.

Bring It Inside After Use

One of the best ways to keep your grill from rusting is to bring it inside after every use. If you live in an area with a lot of rain or snow, consider storing it in a garage or shed.

Be sure to clean it thoroughly before bringing it inside, and ensure it’s completely dry before storing it. You should also check for rust regularly; if you see any, sand it down and repaint the area.

If your grill is made of stainless steel, keeping it clean and dry is especially important, as stainless steel is more susceptible to rusting than other materials.

However, with a little care and attention, you can keep your grill in good condition for years to come.

Final Word

Do grills rust? The answer is yes, but there are ways to prevent it. In this blog post, we’ve outlined the causes of grill corrosion and how you can keep your grill in top condition for years to come. Follow these simple tips and your grill will be good as new – no matter how much rain or snow falls on it.
