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.
Claims28
A process for substantially cleaning a surface that has been treated with a chemical paint remover, wherein said chemical paint remover comprises an organic, acidic or basic compound, and wherein said surface is contaminated with said compound, said process comprising the steps of:
- (A) applying a liquid-state composition to said surface, wherein said liquid-state composition comprises:
- (i) a polymeric component and
- (ii) an agent selected from the group consisting of an absorbant, an acid-neutralizing agent, and a base-neutralizing agent;
- and wherein said liquid-state composition has a cleaning capacity of about 0.10;
- (B) allowing said liquid-state composition to interact with said compound to form a product and to solidify into a solid-state matrix, thereby sequestering said product in said solid-state matrix;
- and
- (C) removing said solid-state matrix from said surface.

- (B) applying a second liquid-state composition to said surface, wherein said second liquid-state composition comprises a polymeric component and has a cleaning capacity of about 0.10;
- (C) allowing said liquid-state compositions to interact with said compound to form a product and to solidify into a single solid-state matrix, thereby sequestering said product in said solid-state matrix;
- and
- (D) removing said solid-state matrix from said surface.
