Promising review: “I bought this after seeing numerous recommendations, and after years of searing and occasionally burning things in my stainless pans, it was time to try to bring them to a better state. Not only did this easily scrub off the latest culinary leavings, it scrubbed off the years of buildup of oil, fat, cooking spray, and whatever else that have been continually baked on in the oven, stove, and dishwasher. A little powder, a dash of water, a quick, light scrub, and…it’s gone? How is that possible? What’s in this stuff? I do not know, I do not care. After scrubbing my enamel stovetop in a fraction of the time with no scratches and better results, I became thoroughly convinced the contents of BKF is not of this realm. It’s magic.” —Bulb
