Lots of things don’t dissolve in water but are still effectively contained by water. That said, I wonder what happens to the water being used for this purpose.

Lots of things don’t dissolve in water but are still effectively contained by water. That said, I wonder what happens to the water being used for this purpose. If it isn’t treated/disposed of somehow, I could see it evaporating and allowing the dust to become airborne again. If this is in a permanent shop environment, it might explain the apparent lack of effectiveness of this solution.
