I had zero luck with my Mapleshade Ionoclast. A Zerostat works much better for me.
Contributing to the problem is that a cocobolo platter (both yours and mine) makes a poor conductor. Static buildup from stylus/groove friction has no easy evacuation path, so it stays on the record. I don't have huge problems with it (adequate humidity) but if I did I might try installing a grounded wire with a few carbon fibers that ride against the record surface. Providing a conductive path from vinyl to ground might help - or not - I haven't actually tried it.
