I tried a Scrub Daddy from BB&B, and although it is a good little scrubber, I didn't find it to be the magic answer to my stove top as demonstrated on QVC yesterday.
Even if I use it, I still have to use a razor blade (for the toughest burned on parts) and a ceramic cleaner made specifically for glass topped stoves, along with a microfiber cloth. I tend to like Weiman's Stove top cleaner best.
I like the Scrub Daddy well enough to have one on hand, and I'm going to try it on some other surfaces that were suggested yesterday, but it doesn't take everything off the stove top that completely.
