Zusammenfassung:	A suspension medium for improved grit delivery in vapor blast operations sets forth addition of a suspending-agent to a blast solution whereby solids are maintained in suspension absent agitation or mixing for at least 60 hours. The suspending agent increases the viscosity and/or density of the blast solution to increase the buoyancy force and/or acts as a dispersant and/or surfactant to maintain suspension of solids in solution over the extended time period. Different concentrations of suspending-agent may be employed with different grit and solid sized particles, depending on the application of vapor blasting at hand. The suspending-agent is preferably biodegradable.
