Did a 15 hour pork cook on my grill after a couple of other grillings and that thing was a greasy mess. A few sprays with the liquid and waited a few minutes before scraping with a wire brush and it all came clean. Really beat my last trial with Dawn and hot water with a scrub brush in the sink! Works really well and got the hardened greasy mess off the grate/drip pan with minimal effort. It really didn't take that much product to get the job done either. With the mess I made I thought I'd use at least half the bottle, only used about an inch of it off the top.Highly recommend. The bottle, while it arrived in tact after a cross country shipment...the trigger sprayer needs improved. It is really cheap, thought I was going to break it taking it from "off" to "spray". Then, the spray action is half hearted.With that said, it has exceeded my expectations by a lot.
