Pyrolytic (self-cleaning oven)
An oven self-cleaning mode that burns baked-on residue to ash at very high heat.
A pyrolytic oven has a self-cleaning cycle that heats the empty cavity to around 480°C, hot enough to reduce baked-on grease and food residue to a fine ash you simply wipe away afterwards. It's the most thorough cleaning method (versus catalytic liners, which absorb grease during normal cooking at lower temperatures, or manual cleaning) but the cycle typically takes two to three hours, uses meaningfully more energy than a normal bake, and requires removing wire racks first since they aren't rated for the heat.
