I have a 600 grit manmade stone and a soft Arkansas that I've been using on my kitchen (& other) cutlery that are pretty badly clogged. One thing that I'm sure isn't helping is that I've been using them dry, as per Jim Juranich's (SP?) research. Is there any way to unclog them, short of grinding them down to fresh abrasive? Can I prevent them from clogging up again without resorting to honing oil? (I hate using oil, it's such a mess). Note: neither of these stones has ever been oiled. Both took several years to get to their present state.


TIA,
