Sharpen your razor's blades by rubbing it on your jeans.
In the list of things that are repeatedly used as lifehacks, denim ranks somewhere on top. Not only it's a great piece of clothing, you can wash with it, clean grime with it, paint on it and make it something else, and also clean your razor blades.
Regular shaving leaves in tiny hairs between the razor blades. If not cleaned properly, these tiny hairs make the next session of shaving really frustrating. And to be honest, getting those hairs out isn't all that easy. But with a piece of denim clothing, you can get it done with the least bit of effort.
Just hold your razor in the direction of the blades and rub it on any piece of denim in the opposite direction. That will make the hairs fall off from between the blades and also make razor sharper. Not bad, huh?
