Necessary tools, which should always be on hand for quick, simple and regular cleaning of the grill:
Before or after the barbecue grill burn. Until it stops smoking, burning is done. Then just use a brush to clean the grill grate.
Do not paint or wax cover. With porcelain coating your next barbecue does not need additional surface treatment. Porcelain is much stronger than any type of paint and wax would be melted when warming up the grill. If you want to occasionally wash the dust and any dirt from the grill, use warm soapy solution.
