In an industrial setting, making things clean is a messy, time-consuming business. You can sandblast, soak, scrub or grind surface contaminants away, and must then dispose of the waste. And cleaning media needs to be replenished.

Okay so my question is how can this scale and work on large infrastructure projects like bridge repair in the northeast where many of our bridges are very rusted. Seems like it could make the repair process a whole lot easier!

  The roi for a mid to large company would be ridiculously fast for that relatively measly sum.
  Not the sort of thing you really expect a home user to lash out and store in the corner :P
