If you have a whetstone that needs cleaning, the process is pretty simple. All you need is water, a cloth, and a whetstone. First, wet the cloth and wring it out. Then place it over the whetstone and hold it there while you pour water over the stone. Let the cloth soak up as much of the water as possible. Once all of the water is absorbed, use your fingers to gently remove any excess liquid from the stone. Finally, dry off the whetstone with the cloth and enjoy your clean blade! ..
