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.
Claims20
A method of blast cleaning a solid surface comprising;
- propelling an abrasive blast media against a solid surface by means of a water-containing pressurized fluid stream to strip contaminants therefrom, said blast media comprising abrasive particles and a surfactant-clathrate compound formed of a surfactant and a water soluble compound having clathration capability.
The method of claim i wherein said abrasive particles are water soluble.
The method of claim i wherein said solid surface is nonmetallic.
