How to care for and maintain your Gravity Series® Half-Grate Griddle Insert

Why it's important to clean & maintain your Flat-Top Griddle Insert

Keeping your half-grate griddle insert clean and properly seasoned isn't just about appearance — it's essential for performance and flavor. Regular cleaning removes stuck-on food and grease that can cause uneven cooking, while consistent seasoning creates a natural non-stick surface that enhances taste and prevents rust. Taking a few extra minutes to care for your griddle pays off with better cooks, less cleanup, and more reliable results all year long.

A well-maintained griddle heats more evenly, lasts longer, and delivers that signature sizzle every time you fire it up.

How to Clean & Maintain Your Masterbuilt Half-Grate Griddle

To keep your Masterbuilt Half-Grate Griddle Insert in top shape and cooking like a champ, proper cleaning and regular seasoning are key. Here's what you need to know:

Before First Use: Season Your Griddle

1. Wipe the griddle surface clean of any debris.
2. Preheat your grill to 250°F (120°C) and let it run for 10–15 minutes until the griddle is hot.
3. Add a small amount of cooking oil and spread it evenly over the surface using paper towels. (Tongs recommended!)
4. Increase the temperature to 400°F (205°C). The oil will begin to smoke—this is normal and part of the seasoning process.
5. Once the smoke dissipates, repeat steps 3–4 at 350°F (177°C).
6. Store in a clean, dry location when not in use.

Pro Tip: Regular seasoning helps prevent rust and builds up a natural non-stick coating.

After Each Cook: Quick Clean

1. While the griddle is still warm (not hot), use a bench scraper to remove excess food or grease.
2. Wipe down with a damp paper towel or cloth.
3. Lightly oil the surface before storing to maintain seasoning.

Deep Cleaning (When Needed)

It's a good idea to give your griddle a deep clean occasionally. This can be after several uses, or the beginning of a new season.

1. Heat griddle to 300°F (149°C).
2. Cover griddle top with coarse salt.
3. Add a small amount of cooking oil to the salt on the griddle top.
4. Use a bench scraper or chainmail to scrub any residue from the griddle surface. Use extreme caution. Griddle will be hot.
5. Use a bench scraper to remove the loose residue from the griddle top.
6. Apply a small amount of warm water to the griddle top.
7. Use chainmail or paper towels to rub water over griddle top. This will remove any remaining food particles. Be sure to use tongs and hot food gloves when scrubbing griddle top. Griddle will be extremely hot.
8. Dry griddle thoroughly.
9. Finish the cleaning process by seasoning your griddle.
