Ok so I am a clean freak but never imagined I would sound like a commercial or Heloise with household hints!!

But - has anyone tried using this product out by Mr. Clean?? It is a white pad that wears away and disappears with use. It looks sort of like a sponge but works like an eraser. I have been using them in my kitchen and was very surprised at the way it cleans the porcelain sink without comet. I saw a commercial on TV yesterday that showed other things like outdoor furniture, crayons, scuff marks on floor and bathroom soap scum. OK, I got out a new one just now and got to work on the bottom of our fiberglass shower stall. Marks that have been there for years and years are gone and so is the white eraser!!

End of commercial...has anyone TRIED this thing?? You just wet it and rub. I don't have any idea how it works because there is no smell and it does not even hurt bare skin.
