I was reading this web page that recommended you clean your used razor with alcohol to kill any bacteria on it before you use it on your face. Bacteria loves and thrives in bathroom settings. I know a lot of guys here are participating in some "30 day razor challenge" might want to consider sterilizing their blades every now and then. Here is the page http://www.getridofthings.com/get-rid-of-razor-bumps.htm article: "Rinse your shaving razor with rubbing alcohol before and after every use, and change the blade at least once a week to get rid of razor bumps. Because razor bumps tend to form just after a shave, you want to make sure there are as few bacteria on your face as possible. Bacteria tend to grow on razors and blades just as easily as they grow on a toothbrush. Keeping your blades sterile with a quick wipe down with rubbing alcohol will ensure a safer shave every time, preventing razor bumps."
