In optics & film usually blowing air is employed, as wiping runs the risk of further scratches in the case of an abrasive particle (e.g. sand)
There are handheld tools (google hand blower bulb), but I would imagine film scanning uses something less manual
Agreed. That was just a starting point for the convo. Seems like any reasonably fast method would either result in damage from particles or would be incredibly slow. Sometimes a blower doesn't do a complete job.
