Is it actually dust or did they "fog" the paint while painting an adjacent panel? Either way, I agree with the guys about wet sanding and polishing. If it was me, since the doors are so flat, I'd use a rubber sanding block with the aforementioned 1500-2000 (I use 2000). The rubber block works on the bumps without taking down the rest of the finish as much.
Sand in one direction and stick with it. (up and down or front and back not in circles) For water, I pre-soak the paper and block for about 30 min. to soften it and avoid gouging. I have a hose trickling water that I hold in my left hand and drizzle on the panel while I'm sanding with my right. this continuously washes away contaminants to avoid re-scratching.
I follow up with a rotary polisher with a wool pad and 3M micro finishing compound.
