I came about this by accident, but works extremely well... If your like me ya hate to shave every day, problem is when after 4 or 5 days the growth is pretty good... So when ya do shave the long hairs get stuck in your razor clogging it up making it tough to continue or use a new blade... I was at the auto parts store and saw a neat little knuckle scrubber which I needed... The next time I shaved, same problem and then thought of the little scrubber and used it to clean the razor blades of the built up hair... This works great and makes a good cleaning tool into a multitasking tool, not to mention saves money on blades... give it a try...<br>
