A friend sent me several boxes of this product as a gift. My stove is almost brand new. I used it on some specks of burned-on oil (carbon) and it did a really good job. I then took it to another friend's house. She had just moved into an apartment with a stove that looked like it hadn't been cleaned in years. Completely greasy, burned-on grease and oil everywhere. I mixed a stronger concentration of cleaner (2 oz). I let it sit for about 1/2 an hour. No fumes, no smell, nothing. Then I went to work with the included scouring pad. The carbon came off with minimal effort. When I was done. The stovetop looked brand new. I did the inside of the oven next...Same results. I can't tell you how impressed I am. You have a customer for as long as you make this product.
Bottom Line: Yes, I would recommend this to a friend
