Abstract
A blast media for stripping contaminants from a solid surface comprises abrasive particles and a surfactant in the form of a granular surfactant-clathrate compound formed of a surfactant and a water soluble compound having clathration capability such as urea. The surfactant reduces the amount of water soluble residues which remain on the targeted surface and enhances the removal of dirt, grease and oil from the targeted surface.
