My fairly new Greenway polishing lap is contaminated. I thought I was dealing with leftover scratches or subsurface damage, so I started a new stone and both preformed and faceted the pavilion entirely with a 600 NuBond lap (big stone, took forever). The finish was a lovely uniform matte surface. I washed the Greenway again (just dishsoap and water, no scrubber of any kind), put it on the platen and laid down a girdle facet. Boom, two not just scratches but gouges immediately dug into that lovely surface.
Is there anything I can do to get the contamination out of the surface, or is it trashed forever? I didn’t even cut but a few stones with it but I left it out unprotected in a room that was then used by a bunch of people for gardening tasks. There are more than just a couple of places I can mark and avoid, I can’t find any area that doesn’t have at least one scratch. The first stone it scratched up was a citrine, the new one that I preformed and faceted on the Nubond 600 is a beautiful synthetic alexandrite.
