Start with your grill upright and remove any grates that are inside of the grill.

Use a charcoal rake or a small garden shovel to remove excess ash and residue in the grill.

Turn the grill on its side and use a pressure washer or hose to clean the inside of it and any extra residue.

Caution: If using a pressure washer, make sure you handle with care. Improper use of the pressure washer could cause injury.
