Seasoning
Applying oil and heat to cast-iron grates to create a non-stick, rust-resistant protective layer called patina.
Why Seasoning Matters
Seasoning:
- Creates a natural non-stick surface
- Prevents rust and corrosion
- Improves flavor—the patina builds with each use
- Extends the life of cast iron grates
- Reduces the need for harsh chemicals
How to Season Grates
After cleaning cast-iron grates:
- Dry grates completely with a clean cloth
- Apply a very light coat of high-smoke-point oil (avocado, vegetable, or canola)
- Use a paper towel to buff away excess oil until barely visible
- Heat the grill to 350-400°F for 15-20 minutes to polymerize the oil
- Cool and repeat for additional layers
Best Oils for Seasoning
- Avocado oil: High smoke point (520°F), neutral flavor
- Vegetable oil: Affordable, 400°F smoke point
- Canola oil: Common, 400°F smoke point
- Avoid: Olive oil, butter (too low smoke point)
Common Questions
Can I season porcelain grates?
No—seasoning is only for cast iron. Porcelain surfaces don't accept a seasoning layer and don't need it.
How often should I season?
After each professional deep clean; every few months during regular use to maintain the patina.
Can I overseason?
Yes—too much oil creates a sticky buildup. Use thin layers and buff away excess.
