A wet grill after several days of rain can develop rust, especially on cast iron cooking grates, burners, heat plates, and other metal components. Properly drying your grill and protecting exposed metal parts helps prevent corrosion, maintain cooking performance, and extend the life of your grill.
If your gas or charcoal grill has been exposed to a wet week, follow these practical steps to dry it out and prevent rust before your next cookout.
1. Remove Standing Water and Dry Your Grill
Start by removing the grill cover and opening the lid to allow trapped moisture to escape. If water has collected inside the grill, firebox, or grease tray, remove it before cleaning.
-
Wipe down the lid, cooking chamber, and exterior surfaces with a dry cloth.
-
Remove cooking grates and other accessible components to help them dry completely.
-
Empty and dry the grease tray.
-
Leave the grill open in a dry, well-ventilated area until all components are thoroughly dry.
Important: Never ignite a grill if water may have entered its electrical components, ignition system, or gas connections. Inspect affected components and follow the manufacturer's safety instructions.
2. Remove Surface Rust from Grill Parts
If you notice small rust spots after a rainy week, address them before corrosion spreads.
-
Cast iron grates: Remove loose rust with an appropriate grill brush, clean as directed by the manufacturer, dry thoroughly, and apply a thin layer of suitable cooking oil.
-
Stainless steel grates: Clean with a non-abrasive brush or approved cleaner, then dry completely.
-
Burners and heat plates: Check for rust, flaking metal, blocked burner ports, or visible damage.
-
Exterior surfaces: Use a suitable cleaner and dry the surface thoroughly.
Light surface rust may be removable, but deeply corroded, cracked, or deteriorating parts may need replacement.
3. Protect Grill Parts from Future Rust
Once your grill is dry and clean, take these steps to reduce future moisture damage.
-
Season cast iron grates: Apply a thin layer of suitable cooking oil to clean, dry cast iron grates, following the manufacturer's instructions.
-
Use a properly fitted grill cover: Choose a weather-resistant cover that allows adequate ventilation.
-
Keep the grill in a dry location: Place it in a sheltered, well-ventilated area away from standing water when possible.
-
Clean grease and debris regularly: Food residue and grease can hold moisture and make maintenance more difficult.
-
Inspect your grill after heavy rain: Check grates, burner tubes, heat plates, grease trays, and ignition components.
4. Which Grill Parts Should You Replace If They Rust?
Not every rust spot means you need a replacement. However, severely damaged parts can affect cooking performance and safety.
| Grill part | Signs it may need replacement |
|---|---|
| Cooking grates | Deep rust, flaking metal, cracks, or broken sections |
| Burner tubes | Severe corrosion, holes, or damaged burner ports |
| Heat plates / Flavorizer bars | Extensive corrosion, holes, or crumbling metal |
| Grease tray | Perforation, severe rust, or structural deterioration |
| Ignition components | Corrosion or persistent ignition problems |
Before ordering replacement parts, confirm your grill's brand, model number, dimensions, and part compatibility.

5. How to Keep Your Grill Dry Between Cookouts
Consistent maintenance is the best way to prevent rust from returning.
-
Dry your grill after rain or cleaning.
-
Clean and season cast iron grates as recommended.
-
Inspect burners, heat plates, and grease trays regularly.
-
Use a well-fitted, ventilated grill cover.
-
Replace severely corroded parts before they affect grill performance.
Final Thoughts
To dry out a wet grill and prevent rust, remove standing water, dry accessible components, clean surface rust, and protect cast iron grates with suitable cooking oil. Regularly inspect your burners, cooking grates, heat plates, and grease tray for corrosion.
When rust causes structural damage or affects performance, replacing the affected grill parts can help restore reliable cooking and extend the life of your grill.
