Before oven self-clean: clear racks, foil and vents
High-temperature oven self-cleaning gets extremely hot. Remove cookware and foil, clear loose soil and confirm ventilation and the manual before starting.
Oven 'self-clean' can mean very different high-temperature or steam cycles. Whirlpool warns that high-heat cycles require removing racks, foil and utensils, keeping ventilation clear, respecting the door lock and protecting birds from fumes. First confirm that the model actually supports the chosen cycle.
