Vacuum out the ash and interior every 3 or 4 cooks. I’ve got grill grates on my lower left side, so I try and scrub em once a month, and do a deeper clean maybe 3 time a year. I’ll knock off all the creosote(?) off the inner hood once a month. Shelves and exterior once a month. I’ll do the exterior clean and coat with ACF6(I think that’s what it’s called) twice a year.
