Many newer ovens feature self-locking cleaning cycles. If yours does not, be sure to double-check the latch before throwing the oven into the cleaning cycle. Not doing so can ignite a grease fire or cause injury to the innocent person who pulls the door open. Keep small children and pets away from the oven during its self-cleaning mode. Never use commercial oven cleaner solutions during self-cleaning mode or at any other time.
Many products are flammable and cause serious injury and death if exposed to high temperatures.
Also, self-cleaning ovens have a delicate surface which has been carefully treated. Commercial oven cleaners damage this surface. Once the surface has been damaged, you will never again be able to use the self-cleaning feature. THE REST OF US For those without self-cleaning ovens, the chore will be a bit more tedious, but doesn't have to stretch into an entire Saturday. Fill the sink with extra-hot, soapy water and place all oven racks and broiling racks into the water.
