Racks
All racks can be washed with warm, soapy water.
Enameled (not shiny) racks can be left in the cavity
during self clean.
Oven Heating Elements
Do not clean the broil element. Any soil will burn off
when the elements are heated.
The bake element is not exposed and is under the oven
floor. Clean the oven floor with warm, soapy water.
Racks may be more difficult to slide, especially after
a self-clean. Put some vegetable oil on a soft cloth or
paper towel and rub onto the left and right edges.
