I have an unfinished basement with framed and insulated (the yellow fiberglass stuff) walls, but no sheet rock. Over time there has been a lot of accumulation of sawdust on the insulation as the area is a workshop. I'm now planning to finish the room. I want to remove the sawdust but I don't see a practical way to vacuum the dust without continually sucking in insulation. Is there a practical way to do this or should I replace the insulation?

Use a vacuum cleaner with a upholstery brush attachment, or "round brush". Hold the insulation with one hand and vacuum with the other.
If you still have problems with loose insulation, lower the suction either with an adjustable vacuum or with a bypass-hole.
Minor amounts of sawdust can be left in the insulation. It's not uncommon for dust to accumulate during electrical/plumbing installations and for it to remain there during insulation and close-up.
