Deep clean inside

Take the inside out and brush it

The quick start guide: "Occasionally removing all the components from the unit and cleaning the grill with a brush."

1. Lift out the Smart Grid System, then the basket and charcoal grate.
2. Lift the fire ring out with both hands, keeping it clear of the rim.
3. Lift the 5 firebox segments out one by one.
4. Lift out the frame and tip the ash into a bucket.
5. Brush or vacuum out the base and the dome. No water or liquids (the manual).
6. Refit everything in the manual's order: see fit the inside parts.
