Abstract
The invention relates to an aqueous hard surface cleaner composition containing a synergistic combination of a surface tension reducing agent, a superwetting agent and an organic coupling/degreasing agent that targets each of the interfaces present when the cleaner is in contact with soil deposit on a hard surface to provide effective cleaning properties with a low concentration of active ingredients.
