On Mondays, I am charged with the duty of trying to get supper on the table for my family. So, what does a culinary baffoon like me make for his family? I do leftovers or sandwiches and last night was leftovers. So I put lasagna into the oven to give it a 20 minute warmup before my wife gets home.
Within a few minutes, I can see smoke rolling out the side of the oven. I'm not worried...it did the same thing just a few days earlier, but I immediately knew that my next duty was to try and clean the beast out.
So, after supper I cruise over the sink, grab a scrub brush and begin the hopeless task of trying to get the black stuff off the coated interior. It obviously wasn't working, so I progress to a hard plastic spatula. Same result. Then I grabbed an everyday butter knife and began doing the scrape. You are probably picking up at this point that I don't have any of the spray oven cleaner. There's a reason for that. They don't work for the black stuff. They work for the greasy gunk, but so does elbow grease.
