I finally found the stainless steel cookie sheets I've been looking for 30 years. I've had one that long and it took a beating and still looked knew. A s.o.s. takes the baked on grease or whatever spilled over on to it right off. Even the backs clean easy. I couldn't wait to bake with my new ones and they performed excellent. I would recommend these to non stick any day. The quality is ...well excellent. I can't wait to start baking Holiday treats.
