Weber barbecues do the bulk of the cleaning work themselves. All you have to do is preheat on a high heat until the food residue burns off. Remnants can then be easily removed from the cooking grate when it is still hot using the specially designed brushes.
Clean or change the grease trays regularly. This will further prevent the risk of fire from grease build up.
Burn off grates at a high heat, brush down and, if necessary, use a Weber grate cleaner.
Only clean enamel and outer barbecue parts with a special barbecue cleaner.
CAUTION: Only clean cast iron by hand. Never put it in the dishwasher!
