Store a Blackstone Griddle for Winter (or Any Long Break)
A Blackstone that sits for months without the right prep comes back rusty. Oil + cover + dry + cool is the four-step storage recipe.

What you need
- Cooking oil
- Paper towels
- Heavy-duty canvas griddle cover
- Dry indoor or covered storage location
Step by step
Deep-scrape and oil before storage
Clean the surface per the after-cook routine — scrape, wipe, rinse-dry, oil. The protective oil layer is what blocks rust during storage.
Wipe excess oil with paper towels
Blackstone: 'rub oil over the surface, wipe off the excess with paper towel.' A thin uniform layer; no puddles.
Disconnect and store the propane tank OUTSIDE
Close the tank valve, disconnect the regulator, and store the tank in a shaded, ventilated outdoor location. Never indoors.
Cover with a heavy-duty canvas griddle cover
Covers protect from scratches, dust, and ambient humidity. A thin plastic tarp is not enough.
Store in a cool, dry location
Garage, shed, or covered patio works IF humidity is low. Damp basements and uncovered outdoor spots will rust the griddle through a cover.
Common mistakes
- Storing with the propane tank attached. Even with the valve closed, propane tanks don't belong indoors. Disconnect and move outdoors every time.
- Stacking objects on the cooking surface. Pointed objects scratch the seasoning and cause rust pits. Keep the surface clear.
- Thin plastic or tarp instead of a griddle cover. Traps condensation — the humidity under a tarp is worse than no cover at all.
Hands-on tips
- Blackstone recommends storing 'in a cool, dry place and use a cover to protect it from humidity in the air.' Humidity is the real enemy, not cold.
- If you store outside, check the griddle monthly — a cover + a quick oil wipe keeps it ready for mid-winter cooks.
Questions people ask
Can I store a Blackstone outside year-round?
Yes, with a heavy-duty cover and periodic oiling. Blackstone specifically allows outdoor storage when covered.
How often should I re-oil during winter storage?
Check monthly. Re-oil if the surface looks dry or shows any rust spots.
