As temperatures begin to drop and outdoor cooking season starts winding down, many Blackstone owners wonder how to properly protect their griddle during the winter months. Whether you live in a region that experiences snow, ice, freezing temperatures, or simply long periods of inactivity, proper winter storage is essential for preventing rust, preserving your seasoning, and ensuring your griddle is ready to cook when spring arrives.
Fortunately, winterizing a Blackstone griddle is neither difficult nor expensive. A few simple steps performed before storage can save you hours of rust removal and re-seasoning later.
This guide will walk you through everything you need to know about storing your Blackstone griddle during winter, from cleaning and oiling to choosing the best cover and storage location.
Why Winter Storage Matters
A Blackstone griddle is built around a carbon steel cooking surface. Carbon steel provides excellent cooking performance, but it is vulnerable to moisture.
Winter weather introduces several threats:
- Snow accumulation
- Ice formation
- Rain and freezing rain
- Condensation
- High humidity
- Wind-driven moisture
Even griddles stored under a cover can develop rust if they are not properly prepared.
The goal of winter storage is to create multiple layers of protection between your griddle and the elements.
Step 1: Thoroughly Clean the Griddle
Before storing your Blackstone for an extended period, perform a complete cleaning.
Start by:
- Heating the griddle.
- Scraping away all food residue.
- Removing grease buildup.
- Wiping the cooking surface clean.
Pay special attention to:
- Corners
- Side walls
- Grease trap
- Rear splash guard
Any leftover food debris can attract moisture and contribute to corrosion during storage.
Step 2: Perform a Light Re-Seasoning
Once the griddle is clean, heat the cooking surface and apply a thin coat of oil.
Recommended oils include:
- Avocado oil
- Canola oil
- Grapeseed oil
- Vegetable oil
Allow the oil to smoke lightly before turning off the burners.
This reinforces the protective seasoning layer before winter begins.
Step 3: Apply a Protective Oil Layer
After the griddle cools, apply one final thin coat of oil across the entire cooking surface.
Don’t forget:
- Side walls
- Rear splash guard
- Corners
This oil layer acts as a moisture barrier during storage.
Many experienced owners use slightly more oil for winter storage than they would after a normal cook.
Step 4: Protect the Cooking Surface
One of the best upgrades for winter storage is a silicone griddle mat.
A silicone mat:
- Blocks moisture
- Prevents dust accumulation
- Reduces condensation
- Helps preserve seasoning
Simply place the mat directly on the cooking surface after applying oil.
If you do not have a silicone mat, the oil layer alone still provides valuable protection.
Step 5: Empty the Grease Trap
Never leave grease in the collection cup during winter.
Old grease can:
- Attract pests
- Create unpleasant odors
- Freeze and expand
- Cause unnecessary mess
Remove and clean:
- Grease cup
- Grease channel
- Grease tray liners
This only takes a few minutes and prevents problems later.
Step 6: Cover the Griddle
A quality cover is your first line of defense against winter weather.
Look for a cover that provides:
- Water resistance
- UV protection
- Secure fit
- Durable stitching
Avoid inexpensive covers that trap moisture.
A breathable cover is often preferable to a completely sealed cover because it allows moisture to escape.
Step 7: Choose the Best Storage Location
Whenever possible, store your Blackstone in a sheltered location.
Ideal locations include:
Garage
The best option for most owners.
Benefits include:
- Protection from snow
- Reduced moisture exposure
- Less temperature fluctuation
Covered Patio
A covered patio provides good protection while keeping the griddle accessible.
Shed
A storage shed can work well if it remains relatively dry.
Outdoors
If outdoor storage is your only option:
- Use a high-quality cover
- Consider a silicone mat
- Check the griddle periodically throughout winter
Common Winter Storage Mistakes
Storing a Dirty Griddle
Food residue and grease can trap moisture and encourage rust.
Always clean before storage.
Skipping the Oil Layer
The seasoning alone may not be enough for months of winter exposure.
A fresh coat of oil provides additional protection.
Leaving Water on the Surface
Even a small amount of moisture can lead to rust over time.
Dry thoroughly before storage.
Ignoring the Grease Trap
Grease left behind can attract rodents and insects.
Clean it completely before winter.
Should You Cook on Your Blackstone During Winter?
Absolutely.
Many owners continue using their Blackstone throughout the winter.
Benefits include:
- Less chance of rust from inactivity
- Fresh seasoning maintenance
- Enjoyment of outdoor cooking year-round
If you cook regularly during winter, simply continue your normal cleaning and maintenance routine.
How to Bring Your Blackstone Out of Winter Storage
When spring arrives:
- Remove the cover.
- Inspect for rust.
- Wipe away excess oil.
- Heat the griddle.
- Apply a fresh coat of seasoning oil.
- Perform a quick seasoning cycle if needed.
Most properly stored griddles require very little work before returning to service.
Signs Your Winter Storage Worked
A properly protected Blackstone should:
- Show little or no rust
- Maintain its dark seasoned appearance
- Feel smooth to the touch
- Require minimal spring maintenance
If rust is present, it is usually minor and can be corrected with light cleaning and re-seasoning.
Frequently Asked Questions
Can I leave my Blackstone outside all winter?
Yes, but proper preparation and a quality cover are essential.
Should I remove the propane tank?
Many owners disconnect and store the tank separately for safety and convenience.
Do I need a silicone mat?
No, but it provides an additional layer of protection and is highly recommended.
How often should I check the griddle during winter?
A quick inspection every few weeks is a good idea, especially if the griddle is stored outdoors.
Final Thoughts
Proper winter storage is one of the easiest ways to extend the life of your Blackstone griddle. By thoroughly cleaning the cooking surface, applying a protective layer of oil, using a quality cover, and choosing the best possible storage location, you can prevent rust and ensure your griddle is ready for another season of outdoor cooking.
A little preparation in the fall can save significant time and frustration in the spring. Treat your Blackstone well during the off-season, and it will reward you with years of reliable cooking performance.
