These are a great product and I am surprised that they were discontinued. I started to use them in the shower, but not for cleaning the acrylic, but for scrubbing my oily skin. They weren't abrasive, as much as stimulating. The last few that I had were used for multiple showers, as they did everything except cleaning my ears. I usually used them to apply body wash and stimulate my skin. If you find any carton of them in the back of a warehouse, I would be glad to purchase them.
