My Bandera is very old. May years of BBQ have passed through its oven. But it has developed a problem, besides the inevitable rust that plagues us all. The door hinge has gotten so stiff that the door does not want to close and open without considerable force. I am becoming afraid that I will bend the metal. Does anybody else have this problem and what cam be done to relieve the stress on the hinges? I have tried to keep it covered but I am not sure that covering it will adequately control corrosion. Maybe it is just getting old and raggedy. Suggestions will be appreciated.
