The Quick Take
To properly store your grill outdoors, always clear out leftover ash or grease to prevent moisture buildup and pest attraction. Coat solid steel or cast-iron cooking surfaces with a thin layer of high-heat cooking oil to create a rust-proof barrier, and always use a fitted, breathable, weather-resistant cover once the grill is completely cool.
Key Facts at a Glance
| Maintenance Step | Guideline |
|---|---|
| Cool-Down Time | 2 to 4 hours (until completely cool to the touch) |
| Cooktop Protection | Thin coat of vegetable or canola oil |
| Ash Removal | Empty completely (ash absorbs moisture and causes rust) |
| Cover Material | Heavy-duty, breathable, waterproof polyester or vinyl |
| Placement | At least 2 feet from siding, under an overhang if possible |
Setting Up Your Grill for the Off-Season
Protecting your grill isn't just a winterization project; it is a daily habit that separates the true aficionado from the guy serving rust-flecked burgers. Every time you leave your grill exposed, humidity and morning dew are plotting against your cooking surfaces. Keeping the elements at bay requires a mix of physical barriers and chemical ones—namely, a good cover and a layer of polymerized oil.
On an Arteflame grill, the flat solid-steel cooktop is practically indestructible, but like any premium steel tool, it thrives on a good seasoning layer. Because the grease naturally drains inward into the fire, clean-up is incredibly simple. A quick scrape of any residue into the center fire and a wipe down with oil while the steel is still warm is usually all it takes to keep it protected from the elements.
For any traditional outdoor grill, the same core rules apply. Moisture trapped inside a closed system or under a cheap, non-breathable tarp is a recipe for disaster. You want air to circulate underneath the cover while keeping the heavy rain off your steel.
Step-by-Step Instructions
- Clean the cooking surface. While the grill is still warm (but not blazing hot), scrape off any food residue. For flat cooktops, push the grease into the fire; for grates, brush them clean.
- Apply a protective oil layer. Wipe down steel or cast-iron grates and griddles with a thin layer of vegetable oil using a paper towel. This creates a hydrophobic barrier against rust.
- Empty the ash and grease. Ash is basically a sponge for humidity. Once the fire is completely out and cold, scoop out the ashes and empty the grease trap.
- Wipe down the exterior. Remove marinades, dust, and pollen from the outside of the grill with a damp cloth and mild soapy water to prevent paint degradation.
- Secure a breathable cover. Once the grill is 100 percent cold, strap on a high-quality, ventilated cover. Tighten the drawstrings so it doesn't blow away into the neighbor's yard during a storm.
Pro Tip: Never put a cover on a grill that is still warm. You will trap condensation underneath the fabric, which accelerates rust—and in the worst-case scenario, you will melt your expensive cover right onto your cooktop.
Common Mistakes to Avoid
- Leaving ash in the firebox: Ash pulls moisture from the air like a magnet, creating a corrosive paste that eats through metal over the winter.
- Using a cheap plastic tarp: Non-breathable plastic traps ground moisture evaporating upward, turning your grill into a rusty terrarium. Invest in a proper cover.
- Skipping the oil: Bare steel rusts. Always wipe down your cooktop with a reliable high-heat oil or a dedicated conditioner like those from Lodge.
- Using the wrong cleaning tools: Cheap wire bristles can snap off and end up in your food. Use a solid wood scraper or heavy-duty cleaning tools from OXO to safely clear your cooktop.
- Forgetting to lock the wheels: A strong gust of wind can turn an uncovered, unlocked grill into a 200-pound battering ram aimed directly at your patio door.
Make It Your Own
Protecting your grill isn't a one-size-fits-all chore. You can adapt these maintenance routines based on your specific climate and backyard setup to ensure your equipment lasts for generations.
- The Winter Warrior: In areas with heavy snow, build a small lean-to or move the grill under a sturdy gazebo to keep the crushing weight of the snow off your cover.
- The Coastal Shield: Saltwater air is brutal on metal. Wipe down the exterior of your grill weekly and double up on your cooktop oiling routine to fight the salt.
- The Fire Pit Conversion: If you have an Arteflame grill, remove the cooktop entirely for the winter and use the heavy steel base purely as a backyard fire pit to stay warm.
Frequently Asked Questions
Can I leave my grill outside in the winter?
Yes, you can leave your grill outside in the winter. As long as it is properly cleaned, oiled, and protected by a high-quality, weather-resistant cover, it will survive the freezing temperatures without issue.
How often should I replace my grill cover?
You should replace your grill cover every 2 to 3 years, depending on your climate. Once the fabric starts to crack, fade heavily, or lose its water repellency, it is no longer protecting your investment.
What is the best oil to prevent grill rust?
The best oil to prevent rust is a high-smoke-point, neutral oil like canola, grapeseed, or vegetable oil. These oils polymerize well onto steel and cast iron, creating a tough seasoning layer that locks out moisture.
Keep the Fire Going
Properly storing and protecting your grill outdoors might not be as glamorous as searing a two-inch thick ribeye, but it is the true mark of a backyard professional. Taking five extra minutes to scrape, oil, and cover your rig means that when the weekend rolls around, you are ready to light a fire, not scrub off a week's worth of rust. Your future self—and your dinner guests—will thank you for the effort. Now get out there, give that steel some love, and lock it down for the night.
