Hello fellow Resin Workers

Can you shed some light onto a small problem??

I am finding that when I grind my saw-cut sections using 2 grades of 
sand paper, (600/1200) fine black spots are settling on the tissue. I 
have tried to wash the out with water, but they don't come off?? It 
must be tiny pieces of dust from the sand paper. I am using water all 
the time, and clean paper. Any ideas??

Thank you
Melanie Black
