This little bar of "soap" does exactly what it is intended to do. Do you have a sponge or rag that has that.....odor? Simply wash your hands under the sink with this little guy and suddenly, your hands smell like hands again. I've used it after handling several "smelly" items, that have a tendency to make an odor stick with you. It's worked consistently every time. There is the science behind it in the description, and it is way over my head, so no need to explain it. Basically, if you are tired of that weird smelly sponge odor sticking with your hands, get this thing.
