Has any one used Scrub Daddy on Le Creuset? Scrub Daddy was featured on Shark Tank, so when I saw it at BB&B I decided to give it a try. I don't have a dishwasher, and conservatively, I would say it cuts my cleaning time in half! It's wonderful and stubborn food comes off like a dream! It says it's scratch free, but even so it does feel a little abrasive to the touch so I'm scared to use it on my Le Creuset. I have a sauce pan, dutch oven and cast iron Le Creuset cookware.
