Instructions
Feel the surface of the stone. A smooth stone indicates that the grit has been covered by displaced stone and metal fragments. Also feel for any cracks or chips in the surface of the stone.
Soak the stone in warm water for fifteen minutes. This will facilitate cleaning by opening the pores of the stone.
Scrub the stone with a toothbrush. The bristles of the toothbrush will displace dust and other debris from the small pores of the stone.
Wipe the surface of the stone with a rag.
Dry the stone before your next use.
