The new IB 15/80 Dry Ice Blaster uses compressed air to propel tiny dry-ice pellets at supersonic speeds so they flash freeze and then lift grime, paint, rust, mold, asphalt and other contaminants from a broad range of surfaces. The pellets quickly dissipate into the air so there's no messy waste water, solvents, sand or other waste, only the soiled contaminant that is easily swept or vacuumed. Dry ice is safe to use on virtually any surface. Estimated list price: $19,995.
