Cast-iron grate care

The fire grate and any cast-iron grates

Kamado Joe gives no care method or interval for the fire grate beyond keeping ash off it.

1. Lift the fire grate out when the grill is cold (see deep clean).
2. Brush off ash and loose scale with a wire brush.
3. Look for cracks or holes burnt through: replace it with BJ-MFGC if so (5-year warranty on cast iron).
4. Refit it ribs side down (Kamado Joe's unboxing video).

Cast-iron cooking grates (an accessory, not in the box): Kamado Joe's video seasons them with oil at 175 °C (350 °F) for 1 hour, twice the first time, then brushes after cooking and wipes with spray oil against rust. Its blog: no soap where possible.
