This is about electric stoves. I have a pet peeve with people who line their drip pans with foil. Yes, that is done so you people don’t have to clean the pan. But it doesn’t look aesthetic. Also, the foils do get dirty and should be changed very frequently if there is a lot of cooking done. Or else, there is the danger of a fire.
Really, the drip pans should be cleaned either right away after getting soiled or along with the evening dishes. Otherwise, the soil causes pitting and the debris doesn’t come off. That is why I like my smooth cook-top. It forces the owner to keep the cooking area clean.
