Trying to look your best and keep your unruly facial hair in check is expensive business - new razor blades are a bleedin\' rip off! And don\'t get us started on those fancy-schmancy hipster blade subscriptions. The likes of Gillette and co say that the typical razor blade lasts only five weeks before it\'s useless. But it turns out most of the time the blades aren\'t even blunt, they\'re just clogged up with a load of hair, dead skin and other bathroom detritus. Remove this unwanted surface gunk and the blades beneath are still good to go, and can be used again and again!
