Actually I just tried docker system prune. It warns:

docker system prune
WARNING! This will remove:
  - all stopped containers
  - all networks not used by at least one container
  - all dangling images
  - all dangling build cache

The similar command would be docker image prune which just removes the dangling images. I mixed the 2 separate commands together in my above comment. System prune is more aggressive and "nuclear". But also useful!
