Just picked up a new 1000 and 5000 grit water stone (professional series) from Shapton. I know these stones do not have to be soaked like traditional water sones but I have a spray bottle with clean water. My question is I have heard others talk about putting a drop or two of Dawn dishwashing liquid in the bottle to make the sharpening process even easier... How many of you guys who own these stones do this vs just clean water? Just interested? Thanks.
