Scratching Laps

I have been using a 600 grit standard lap for cutting gemstone facets for several months when suddenly I started getting deep scratches on the facet. I have tried cleaning the lap, but I still get the scratches. The same thing happened a few months ago when I was using a standard 1200 grit lap. I havent been able to use that lap since. Does any one have any idea what could be causing the scratches?
