Change that razor blade that you use to shave your facial hair right this instant. Its filled with germs and bacteria. If you don't want to do that, a simple hack such as  simply putting your filthy razor in this case and a beam of UV light will zap viruses and bacteria, like salmonella. The UV bulb will last 2,000 hours,supposedly obviating the need for you to change your blade.

Or better yet, don't keep using the same blade all the time.
