ABSTRACT:
This invention relates to a process of cleaning a surface soiled with a staining agent. The method includes the steps of applying to the soiled surface a highly cross-linked macroporous hydrophobic copolymer which contains a chemical entrapped therein which is a solvent for the staining agent present on the soiled surface, dissolving the staining agent with the solvent, absorbing the staining agent into the solvent entrapped copolymer, and removing the copolymer containing the solvent and the dissolved staining agent from the surface.
