How to clean a charcoal grill
Locate a suitable area to clean your grill.
This area should be away from your campsite or off to the side of your yard. You'll be brushing ash and encrusted char off the grill at this location, so it should be far from walking paths.
Choosing a cleaning location far from walking paths will prevent ash and char from being tracked around your campsite or home. Brush dirtiness from the grate.
