If you have an oven with a self-cleaning function, you probably know that you can’t just leave the house and let it do its thing. This is because the self-cleaning cycle involves the use of extreme heat and fumes, which can be dangerous if left unsupervised. For this reason, it’s always a good idea to open the windows during the self-cleaning cycle to help ventilate the kitchen. Additionally, you may want to consider turning on the range hood or overhead exhaust fan to help remove any lingering fumes. Taking these precautions will help to ensure that your kitchen is safe during the self-cleaning cycle.
