I see those scratches left behind quite often and always makes me think poor workmanship cuz they didn't bother to smooth it out. I usually follow up sanding with a finer grit (100 or 120) before calling it done. A fine to medium sanding sponge works well for this purpose.
What inspectorD suggests, using a damp sponge or rag, also works well, and doesn't create yet more dust. Don't get it too wet though or you'll replace the scrath marks with swirl marks. Primer and a couple of coats of paint do tend to fill in the finest scratches, but better to make sure it's smooth before priming.
