ABSTRACT:
A process for cleaning a surface contaminated with an organic, acidic or basic contaminant. In the process, a liquid-state composition including an agent selected form the group consisting of an absorbant, an acid-neutralizing agent and a base-neutralizing agent is applied to the surface, and allowed to interact with the contaminant to form a product and to solidify into a solid-state matrix which sequesters the product. The solid-state matrix is then removed from the surface, thereby substantially cleaning the surface of the contaminant. There is also a process wherein a second liquid-state composition including a functionally different composition is applied to the surface. The second liquid-state composition may enhance the removability of the solid-state matrix from the surface.
