Yes. No matter how much you rinse scum & crud there is lots left in place on the razor & blade. Why wouldn't you rinse the blade & dry it. I suppose then after you clean & dry your razor you could put it back in for the next time? Doesn't anyone see the connection between all the scummy used razors sold & wonder why?? Do you really think people didn't rinse razors when they shaved in past years? I think it is because people didn't remove the blade & clean the razor & blade. Maybe back then they didn't do much rinsing or cleaning after shaving? But, what do I know. I've only been at it for about 53 years. I remove the blade, rinse, clean everything & dry. Nice clean razor & blade to shave with the next time.
