I thought I was dreaming when I saw these. As chief cook, maintenence mechanic, and woman of letters, I was choosen to repair the bathroom leaks and grout. Over 45 years, I'm used to being choosen. I noticed that the tile board (which I hate and will be replaced at a later time) had a pall over it. Apparently this is due to hard water and soap scum. IT CANNOT LIVE HERE. I ran out of options for cleaning it and stated to use a razor. That works fine but the razor even with the holder was too small to be practicle. Enter these brutes. They do a fabulous job and save bodily wear and tear. Btw, I created a tool for the grout lines from some household items. I can forsee plenty of uses for these as we , I, remodel the house in my retirement.
