It's a bit of a joke really but a little while ago while looking through Barbicide's website I noticed that you can become "Barbicide Certified". All it takes is to watch their short video on the product and how to use it then get a decent score on a simple multiple choice test. When you pass you can download your certificate and print it out. I won't be buying a gold frame and hanging this one in my office/den though. A couple of things I did learn: the manufacturer recommends a full 10-minute soak, and that the solution should be changed every 24 hours. That's fine by me as I only use it when I get a new razor or give an old one away. But I've heard of people just giving razors a quick dip, and keeping the same solution for months so maybe those folks should take note.
