Shut off the power to the range, unplug the power cord and wait for the appliance to cool completely.
Open the range door and take out the wire racks to make room for you to work.
Remove the screws at the two connection points in the back wall of the range for the top and bottom heating elements. Pull gently on each element to disconnect it from the range.
Place a square of duct tape over the connection sockets for the heating elements to prevent oven cleaner from getting inside.
Spray oven cleaner inside the range as you normally would in preparation for scrubbing the interior.
Remove the duct tape to reconnect the range heating elements when you are finished cleaning.
