Have the griddles brushed in hot water, oiled with cooking oil, baked in the Smoker at about 250 ° C and then inaugurated on the charcoal grill with burgers. Great Thing. No flaming inferno, no fat dripping into the fire - which is very good and healthy. By branding and lubricate the plates did not burn the meat firmly. As with all Gußeisentöpfen and pans: cleaning with hot water and brush without detergent. After slightly dry with cooking oil or bacon rind grease. So the panels do not rust and you forever what of. Do not give into the dishwasher !!!
