How to Prevent Rust on Cast Iron Grills: Vessils Cast Iron Grill Care and BBQ Anti-Rust Tips

Cast iron grill grates are prized for their exceptional heat retention and legendary searing power-making them a favorite among grilling enthusiasts who use Vessils Kamado grills. However, without proper care, cast iron is prone to rust, which can shorten the lifespan of your grill and impact cooking performance. This guide covers everything you need to know about how to prevent rust on cast iron grills, with actionable BBQ anti-rust tips and cast iron grill care strategies tailored for Vessils Kamado owners.

Why Does Cast Iron Rust?

Cast iron is a porous material that readily absorbs moisture and oxygen, both of which contribute to rust formation. Exposure to humidity, rain, or even residual moisture after cleaning can accelerate the process. The good news: with consistent care, you can keep your cast iron grates rust-free and performing at their best for years.

1. Season Your Cast Iron Grates Regularly

The foundation of cast iron grill care is seasoning. Seasoning involves coating the grates with a thin layer of oil and heating them, creating a natural, protective barrier that repels moisture and prevents rust.

  • How to Season: After cleaning and drying your grates, brush them with a high-smoke-point oil such as vegetable, canola, or grapeseed oil. Avoid salted fats like butter or margarine, as they burn off at low temperatures and offer little protection.

  • Bake the Oil In: Place the oiled grates in a preheated grill (about 350–400°F) for 40–60 minutes, then let them cool naturally. This bonds the oil to the metal, forming a durable anti-rust layer.

  • Re-season After Each Use: After grilling, while the grates are still warm, apply another light coat of oil to maintain the protective layer.

2. Clean Your Grates After Every Cook

Food residue and grease can trap moisture, leading to rust. Proper cleaning is a key BBQ anti-rust tip.

  • Scrape and Brush: Use a grill brush or scraper to remove food particles and burnt-on residue after each cook. For stubborn spots, a half onion can be used to help clean the grates.

  • Avoid Water When Possible: If you must wash with water, dry the grates thoroughly immediately after cleaning. Never let them air-dry, as this encourages rust.

  • No Harsh Chemicals: Avoid soaps with citrus or abrasive cleaners, which can strip away seasoning and promote corrosion.

3. Oil Your Grates to Prevent Grill Rust

Oiling is crucial for cast iron grill care and helps create a moisture-resistant surface.

  • Apply Oil After Cleaning: Once the grates are clean and dry, use a paper towel dipped in oil to coat all surfaces. This simple step is one of the most effective ways to prevent grill rust.

  • Choose the Right Oil: Vegetable, canola, or grapeseed oils are ideal due to their high smoke points and neutral flavors.

4. Store and Cover Your Vessils Kamado Grill Properly

Environmental exposure is a major cause of rust. Protect your grill with these BBQ anti-rust tips:

  • Use a Weatherproof Cover: Always cover your Vessils Kamado grill when not in use. A high-quality, weather-resistant cover shields your grill from rain, humidity, and airborne contaminants.

  • Store Indoors When Possible: If you won’t be grilling for an extended period, store your grates in a dry, warm place. Coat them in oil and wrap in a plastic bag for extra protection.

  • Keep Vents Open Slightly: This prevents condensation from building up inside the grill, further reducing rust risk.

5. Inspect and Address Rust Early

Even with diligent care, minor rust spots can occasionally appear. Early intervention is key:

  • Remove Rust Promptly: Use a wire brush or non-scratch scrubber to remove surface rust. For stubborn patches, a paste of vinegar and baking soda can help.

  • Re-season Immediately: After removing rust, re-season the grates to restore their protective coating.
