The one or more surfactants are typically chosen from alcohol alkoxylate, an alkyl phenol ethoxylate, a terpene, a terpene alkoxylate or any derivates thereof. Optionally, additional components or additives including delaminates such as pinene and d- limonene, fragrances, whiteners, stabilizers, thickeners and the like can be added to the composition. The industrial or consumer application selected from the group consisting of a graffiti cleaner, a painted-substrate cleaner, an ink cleaner, a metal substrate cleaner, a plastic substrate cleaner, an environmentally friendly cleaner, a stain-spot cleaner, an industrial hand cleaner, a resin cleaner, a tar resin cleaner, a textile cleaner, a paint stripper and any combination thereof.
