The present invention is directed to a composition comprising (a) surfactants, (b) a sequestrant, and (c) a plasticizer/solvent. The composition may also contain (d) a hydrolyzing agent, e.g., a strong base compound and other additives. The composition of the present invention is free of chlorinated solvents, environmentally safe and user-friendly. In one embodiment, the composition further comprises a hydrolyzing agent present in an amount sufficient to reduce at least one of mechanical strength and adhesion between the coating and the substrate. Another embodiment of the invention is a method for removing paint or a coating from a substrate comprising applying a paint or coating removing effective amount of a composition comprising the compositions described herein to the substrate. Yet another embodiment of the invention is a method for cleaning a substrate comprising applying a cleaning effective amount of the composition of the present invention to the substrate.
