"Splash-and-Go" stones do not like long-term storage in water. Use only as much water as the stone requires. Do not immerse stones in a pool of water. After sharpening, wipe the stone immediately with a towel. This will make the stone look clean and get the drying process started. Place the stone to dry in such a position that it does not touch a solid surface. Put the stone lying on top of a pen, for example. Allow the stone to dry slowly and quietly, without separate additional heating. Do not place the stone in direct sunlight. And do not allow the stone to freeze when wet. It takes more than a day to dry. Store the stone protected from knocks, e.g., in its box, without any original foam padding. When wet, do not put the whetstone in a plastic bag.
