How to clean a rusty grill

If you’re a barbecue enthusiast, then you know that cleaning your grill is just as important as cooking on it. However, when you’re dealing with a rusty grill, the cleaning process can seem daunting. But fear not, because, in this article, we’ll show you how to clean a rusty grill and get it looking as good as new. Whether you’re a seasoned grill master or a novice, these tips and tricks will help you tackle the rust and restore your grill to its former glory. So let’s get started!

Why Are My Grill Grates Rusting?

Grill grates rust for several reasons. The main culprit is exposure to moisture. When your grill grates get wet from rain, dew, or excess grease and are not dried properly, it creates the perfect environment for rust to form. 

Rust requires three elements: iron, water, and oxygen. The iron is provided by the steel grates, and exposure to water and oxygen in the air allows rust to chemically form on the grates. Another reason grill grates rust is the lack of maintenance. Not regularly cleaning and oiling your grates allows rust spots to get started, especially in areas where grease and debris build-up. Harsh cleaners can also speed up rust by eroding the grates’ protective coating. 

The best ways to prevent rust on your grill grates are: keep them covered when not in use, dry them after each use, regularly clean them with mild detergent and oil, and re-season them annually with cooking oil. Following these best practices will help keep your grill grates in prime shape. (edited)

Is it OK to Grill on Rusted Grates?

Grilling on rusted grates is not recommended and can be unsafe. Rusted grates can release dangerous compounds into your food as you cook. When metal like steel grates rusts, it forms iron oxide – also known as rust. 

At high temperatures, this rust can break down further and release iron and iron-rich particles that end up in your food. Consuming too much iron can be unhealthy and may cause nausea, constipation, and stomach pain. 

Rusted grates also become more fragile and brittle over time and may start to flake while cooking, leaving rust flakes and metal bits on your food. For the best quality and safety, you should replace grates that show signs of rust or heavy corrosion. 

If replacement is not possible, scrub off as much of the rust as possible, re-season the grates with oil, and be very careful when handling and grilling on them, inspecting the food carefully before eating. It is best to avoid grilling on badly rusted grates altogether if you can. Your health and the quality of your meal are worth the investment in a new set of grill grates. 

How to clean a rusty grill – The simple ways

Cleaning a rusty grill may seem like a daunting task, but with a little bit of effort and the right tools, it’s quite simple. Here are some simple ways to clean a rusty grill:

How to clean your grill with salt and vinegar

Cleaning your grill with salt and vinegar is an effective and natural way to remove built-up grime and grease. Here are the steps to follow:

Heat your grill to medium-high. The heat will help loosen the built-up grease and grime on the grates.

Pour about 1/2 cup of table salt onto the grates. The salt acts as an abrasive to scrub off stuck-on particles.

Scrub the grates thoroughly with a stiff wire brush or scouring pad. Scrub until most of the debris has been loosened.

Pour about 1/2 cup of white vinegar onto the grates. The vinegar helps degrease and loosen any remaining stuck-on mess.

Clean your grill directly after each use

Cleaning your grill directly after each use is an important step to keep your grill in good condition and prolong its lifespan. Here are some tips for cleaning your grill after each use:

Heat the grill for 10-15 minutes after cooking to loosen stuck-on foods. Then turn off the grill and let it cool enough to handle. The heat will make cleaning much easier.

Use a sturdy grill brush to scrape off any loose debris from the grate surfaces. For stuck-on messes, scrub with the brush. Empty your drip tray of excess grease.

Apply a degreaser to baked-on messes on the grates. Let it sit for several minutes before scrubbing off with the grill brush. You can use a commercial degreaser or a DIY mix of dish soap, lemon juice, and warm water.

Use tongs to remove larger stuck pieces of food from the grates. For small bits, scrub with the grill brush and degreaser solution.

Wipe down the entire surface of the grates with water or a vinegar/water solution. Rinse well and pat dry completely with paper towels or rags.

Coat your grill grates in oil or melted shortening after drying. The oil creates a protective barrier preventing rust and sticking. Wipe off excess oil with paper towels.

Clean your burner tubes and venturi tubes with a small bottle brush or pipe cleaners. Remove any clogs to allow gas to flow freely.

Scrape out your grease trap and change the liner. Empty and wipe down your drip/grease tray.

Wash all tools used including grill brushes, pans, tongs, etc. Scrub brushes to remove built-up grease before storing.

Cover your grill to protect it from weather and pests. Keep covered when not in use.

For tough stuck-on messes, you may need to scrub a couple of times. It is much easier to clean your grill immediately after cooking before the residue hardens.

Making grill cleaning a part of your routine after each use is the best way to prevent buildup and keep your grill in top shape. Scrubbing stuck-on foods, degreasing grates, and seasoning with oil will help ensure your grill is ready for next time and will last longer. Keep your grill covered when not in use.

Grill Maintenance

Regular grill maintenance is important to ensure that your grill stays in good condition and functions properly. Here are some tips for maintaining your grill:

Clean your grill grates after every use. Scrub with a grill brush to remove stuck-on foods and grease. Coat grates in oil or melted shortening to prevent rust.

Empty your grease/drip tray after each cookout. Wipe down the tray with hot, soapy water and replace the foil liner regularly.

Inspect burner tubes and venturi tubes for clogs and clean them out with a bottle brush or pipe cleaners. Clogs prevent proper gas flow.

Check igniters and spark plugs before each use and replace them if not working properly. Igniters/sparks light the burners.

Replace grill grates once they start to deteriorate or no longer sit level. Uneven, damaged grates make cooking difficult and unsafe.

Deep clean your grill once a month or if you notice grease fires or uneven heating. Remove grates and trays to clean built-up grease and grime.

Check propane levels before each use if you have a gas grill. Refill the tank when it reaches 30% to avoid running out during cooking.

Perform burner tune-ups as recommended in your owner’s manual. Tune-ups keep burners heating properly and prevent overheating.

Wipe down the exterior of the grill after each use to remove splatters and spills. Baked-on messes are hard to remove if left to sit.

Lubricate and check lid hinges and knobs to ensure parts are moving freely. Replace any broken parts.

Check and replace fuel hoses before each season or if cracks are visible. Fuel hoses deliver propane/natural gas to the burners. Cracked hoses are unsafe.

Cover your grill when not in use to protect it from weather and pests. Covers prevent rust and keep grills in working condition longer.

Consult your owner’s manual for any specific maintenance recommendations for your grill model. Perform all recommended checks and care.

Keeping up with routine grill maintenance ensures your grill cooks safely and lasts longer. Be diligent in cleaning, inspecting parts, and making necessary replacements to keep your grill in prime shape year after year. Covering, cleaning, and checking propane levels should become second nature.

Prevent Rust on Grill

Preventing rust on your grill is important to keep it in good condition and avoid health hazards caused by rust ingestion. Here are some tips to prevent rust on your grill:

Clean your grill grates after every use. Scrub with a grill brush to remove stuck-on foods and grease. Coat grates in oil or melted shortening after drying to prevent rust.

Wipe down the entire surface of the grill with water or a degreaser solution after each use. Rinse well, dry completely, and coat in oil.

Cover your grill when not in use to protect it from moisture in the air. Wet grill surfaces rust quickly if left unprotected. Remove the cover and open the grill before using it.

Choose a stainless steel or porcelain-coated grill if possible. These materials are rust-resistant and easier to maintain. Mild steel and cast iron grills rust more easily.

Perform regular maintenance like burner tune-ups, grate replacements, and deep cleans. Built-up grease and grime accelerate rusting.

Use a commercial rust inhibitor product on your grates, burner tubes, and drip trays if rust starts to form. Scrub off any surface rust before applying. Reapply as directed.

Wipe down the exterior of the grill after each use to remove splatter and spills. Baked-on messes lead to rust.

Lubricate lid hinges, knobs, and any moving parts. Apply water-resistant grease to prevent rusting.

Season your grates before first use and re-season them at the start of each grilling season. Coat grates in oil and heat the grill on high for 30 minutes. Let cool, and wipe off excess oil with paper towels. Seasoning prevents rust.

For rust stains on stainless steel or porcelain grills, scrub with an abrasive sponge or scrubber dipped in lemon juice or vinegar. Let sit, then scrub off. Pat dry and coat in oil.

Avoid harsh chemicals, abrasive cleaners, and scratching tools which can damage protective coatings and speed up rusting.

Make rust prevention a priority to keep your grill in top shape for longer. Diligent cleaning, drying, oiling, and covering your grill after each use will help safeguard surfaces. Performing tune-ups and grate replacements at the first sign of deterioration also wards off the rust.
