I have a project, though more of a construction project, and less wood working. I’m putting up Western Red Cedar (select tight knot) under my soffits. The cedar has a planed and rough side, and the planed side will be visible.

Prior to staining the wood I am using a random orbital sander to removed the crushed surface, caused by the planing process.

After sanding a few sample boards, then wiping with a damp cloth, it seems the knots still have a white appearance from the dust (after drying). I wiped pretty thoroughly, but still some are whitish in appearance.

Is there a good trick to to remove the sanding dust, easily? That is the biggest challenge at the moment, and I have a few thousand feet of this wood to go.

Also, I experimenting between 80-grit and 100-grit. Does anyone know what grit is optimal for opening the pores in WRC?

try 120 – 150 grit and compressed air or vacuum

So, moving up in grit will make the dust easier to remove from the surface before stain?

Air compressor and a blower nozzle. I;’ve sued a leaf blower a lot for things like this as well.
