Please refer to the user manual to check if your oven has a self-cleaning function. If yes, follow the instructions in the user manual to activate the self-cleaning process.
Before doing so wipe away spills, pools of oil, and excessive debris with a cloth. Those may cause smoke mission and possibly be a fire risk. Do not clean oven parts or accessories in the self-cleaning oven. The light in the oven cannot be turned on during the self-cleaning process. The special heat-resistant enamel and the polished components in the oven may become discoloured over time. This is normal and does not affect operation. Do not use scouring pads, abrasive cleaners or cleaners with high alcohol content, as they might damage the oven. Remove all accessories, racks and broiling pans before activating the self-cleaning process. In double ovens, the self-cleaning process is only available for one oven at a time.
