Is there really a grit on them that "can" come off.
The grit comes from the material you just sanded.
Yes, it comes off. (otherwise we wouldn't be sanding! :tongue: )
If you just leave them all in the water, the grit is free to float
from pad to pad.
Nothing worse than getting some 100 grit sized particles on your
12,000 pad and then grinding it into your beautiful finish..
ps.. the delaminating we're talking about is from the pads, not
the sheets. The sheets go in the wash or stay in water just fine.
But the pads are small sheets glued to a sponge/foam block. And
that glue can break down.
