Has anyone had a chance to use this product? I was impressed: http://www.homemadesimple.com/mrclea.../reviews.shtml My dining table has a tile surface and while I've kept the grout free of stains, dust particles and lint collect and can't be removed very easily. My mom gave me one of these pads after my brother gave one to her and I thought I'd give it a try on the grout. The foam pad is pliable enough to get into the grooves and the dust and lint clings to the porous surface. It was great! I was starting to wonder if I'd made a bad purchase and was picturing the grout looking progressively nasty over the years.
