That’s right there is a fume free oven cleaner. However heavy duty works best. Our greasy cooking begs for oven cleaner…but again want stress that it just be done in a well ventilated place. If you scrub the outside of your pots day with scouring pads and Ajax/comet/Brillo pads they probably won’t require oven cleaner. Remember to use oven cleaner on te outside surfaces of pots/pans only. Don’t not use it on the cooking surface which comes in contact with food.
