Ammonia is great on grease,but try to do it outside, the fumes really aren't good for your lungs!! And remember to NEVER NEVER mix ammonia and chlorine (any chlorox cleaner) because they produce potent TOXIC fumes :shock: :shock:
I used an ammonia solution to try to clean the grime off the kitchen cabinets in a house we purchased..well, not only did the greasy stuff come off...so did the finish!!! That was one refinishing project I hadn't planned for :lol: :lol:
I use windex on my stove quite frequently, it keeps the greasy crud to a minimum.
