Keeping your grill rust-free is easier than you think, and we've got all the tips and tricks you need. Let’s get that BBQ shining like new!
What Causes Rust on BBQs?
Rust, or iron oxide, forms when iron combines with oxygen and moisture over time. While it’s a natural process, it’s not ideal for your barbecue. Several factors contribute to rust formation such as:
Exposure to Moisture
Whether it’s rain, humidity, or even condensation, prolonged exposure to water is the main culprit behind rust.
Cooking Residue
Grease, sauces, and food particles left on your grill after cooking can trap moisture and speed up corrosion.
Salt in the Air
If you live near the coast, the salt in the air can accelerate rusting, especially on grills stored outdoors.
Scratches or Chips
Protective coatings, such as enamel or stainless-steel layers, can become damaged through wear and tear, exposing the underlying metal to moisture and air.
Improper Storage
Leaving your BBQ uncovered or in damp environments increases its vulnerability to rust.
Why Preventing Rust is Important
Taking steps to prevent rust on your barbecue isn’t just about aesthetics—it’s about functionality, safety, and preserving your investment. Here’s why it matters:
Prolonged Lifespan
Rust corrodes metal, weakening your BBQ’s structure over time. Preventing rust helps you avoid costly repairs or replacements.
Health and Safety
Cooking on rusted grates isn’t safe. Rust particles can transfer to your food, affecting taste and potentially causing health issues if consumed regularly.
Improved Appearance
A clean, rust-free BBQ looks more inviting and gives the impression of a well-maintained cooking station, perfect for impressing guests.
Cost-Effectiveness
By preventing rust, you reduce the need for frequent cleaning, replacements, or professional maintenance, saving you time and money.
Effective Ways to Remove Rust from Your BBQ
Scrub It Off with a Grill Brush
Grab a sturdy grill brush or some steel wool. Heat your grill up a bit first to loosen things up, then scrub those rusty bits good. Give it a soapy wash and dry it completely to keep that rust from coming back.
Try a Vinegar and Baking Soda Solution
Vinegar and baking soda are a dynamic duo against tougher rust. Mix them into a paste, slather it on the rusted spots, and let it chill for 15-30 minutes. Then, grab a non-scratch sponge or brush and scrub away. Rinse with warm water and voila – rust be gone! This method is eco-friendly and gentle on your grill.
Use Lemon and Salt for Stubborn Spots
Lemon and salt are a rust-busting combo! Sprinkle salt on the problem areas, rub with a lemon half, and let it sit. Then, scrub, rinse, and dry.
Consider Rust Removal Products for Severe Cases
For seriously stubborn rust, it's time to bring in the big guns: rust removers. Remember, safety first! Choose a food-safe product specifically for grills and follow the instructions to the letter. Once that rust is banished, don't forget to re-season those grates to keep them protected.
How to Prevent Rust on Your BBQ
Clean Your BBQ After Each Use
Cleaning your BBQ immediately after cooking is one of the best ways to prevent rust. For gas grills, crank the heat to burn off any leftover bits, then brush away the ashes. If you're using a charcoal grill, toss out those ashes. Finish off with a soapy scrub and a good dry – your BBQ will thank you!
Season Your Grill Regularly
Seasoning your BBQ grates creates a protective barrier against moisture. After cleaning and drying the grill, apply a thin layer of high-smoke-point oil like vegetable or canola oil. Heat the grill for a short time to bond the oil to the surface, providing additional rust protection.
Use a Durable BBQ Cover
A high-quality, weatherproof BBQ cover is essential for keeping rain, snow, and humidity at bay. Always ensure your BBQ is fully dry before covering it and take off the cover occasionally to avoid trapping moisture. Our range of tailored BBQ covers is designed to provide year-round protection, keeping your grill rust-free.
Choose Rust-Resistant Materials
Choosing a BBQ made with stainless steel or rust-resistant enamelled steel significantly reduces the risk of rust. Stainless steel's chromium content and enamelled steel's protective coating prevent oxidation, ensuring a durable and long-lasting BBQ that requires minimal maintenance.
Apply an Anti-Rust Spray
To give your BBQ an extra layer of protection, consider using a specialised anti-rust spray. Some come in finishes like black for a sleek look. These sprays create a durable barrier against moisture and can be applied to metal surfaces prone to rusting. Be sure to clean and dry your BBQ thoroughly before applying for the best results.
Maintenance Tips to Keep Your BBQ Rust-Free
Inspect and Address Rust Spots Early
Regularly check your BBQ for any signs of rust, especially around hinges, handles, and grill grates. If you spot rust, act immediately to prevent it from spreading. Use a wire brush or steel wool to scrub away the rust, and follow up with a rust-prevention spray or a re-seasoning session to restore protection.
Clean Thoroughly After Cooking Saucy or Sticky Foods
BBQ sauces and marinades can drip and stick to grill parts, potentially causing corrosion over time. After cooking with these ingredients, clean your BBQ thoroughly to remove residue. Sticky build-up can trap moisture, leading to rust if not addressed.
Replace Worn or Damaged Parts
If any parts of your BBQ show significant rust or wear beyond repair, replace them promptly. Grates, burners, and even small screws or bolts can often be swapped out to extend the life of your BBQ. Keeping your unit in good working order ensures it stays rust-free and performs well. Looking for spare parts for a CosmoGrill? Check our spare parts page!
