How do I clean this mess in my oven?
This was a first.I made a macaroni & cheese casserole in a Pyrex baking dish. When I opened the oven, the Pyrex dish had exploded. I tried to clean up as much as quickly as I could. After the oven cooled I “swept” the glass out. I can’t get the cheese off the bottom of the oven & the oven keeps smoking. I also don’t want to damage the heating element. I tried using lemons,etc... any suggestions would be greatly appreciated. Thank you.
