I watched the manufacturer's video on YouTube. I followed their instructions, such as using a razor blade to scrape off as much calcium as possible. I then applied a thick coat and covered it with plastic wrap as detailed in the video. The next day I hoped that the remaining calcium would have been scraped off or rubbed off. It did absolutely nothing. I scraped it with a razor and wiped it with a 3M tissue and it made no difference. I hate spending my retirement money on products that don't work. I do not recommend spending money on this product.
