I find when I wet my Naniwa superstones some dark speckles appear. I've been using a DMT D8C to flatten and the Naniwa dressing stone. These speckles go away when the stone dries. The photo is of the 1000, but i notice on the 5000. I think the hone is still working fine. Am I doing something wrong? Has anyone else noticed this?
