collected dust

Gathered airborne particles

To collect dust is to sit unused or neglected for a long time, accumulating the literal dust that settles on stationary objects: That exercise bike has just collected dust since January.

The phrase emphasizes abandonment—something bought with good intentions but forgotten, or a project started but never finished.
