my grill has 4 cast iron grilling surfaces and every time i cook on it a couple days later its rusting. i seasoned them (cooking them at 400 degrees and put oil on them every 20 minutes for so long and its not doinig anything. please help
Its a gas grill and the back 2 burners feels significantly hotter than the front burner(with and without grill plates and flavorizer bars). I cant figure it out! I’ve scrubbed the pipes, put fresh propane, tightened everything! Please help!
