Not a big deal on a nano, or maybe it is. Still stress on the inhabitants and then trying to figure out how to keep the mess to a minimum.

You cold use the micro mesh polishing cloths. They are basically like sandpaper but on a cloth backing and go to 12,000 grit. They are meant for wet sanding so you could probably use it inside the tank. I doubt the small amount of plastic dust released into the water would harm anything and could probably be mostly removed by filtering and a couple of water changes. I believe they were originally made to polish scratches out of acrylic aircraft windows so they would be perfect for acrylic tanks.
