24 hours, three ingredients and very little elbow grease took my grungy burner drip pans from ugly to super clean the easy way. Some ammonia, a gallon zip lock bag for each drip pan and a Scotch bright sponge with a non stick pad on the back.
pour c ammonia into a large ziploc bag and place one stove drip pan into the bag. Seal and place outside overnight (so the fumes don't escape into your house). The next all you have to do is rinse an dry them off and your drip pans are good as new!
