An aqueous aerosol bathroom cleaner includes a surfactant, a water-soluble or dispersible organic solvent, a chelating agent and a propellant that comprises n-butane. Comparative data demonstrate that the presence of n-butane in the composition enhances the rate of bathroom soap scum removal relative to aerosol compositions that do not contain n-butane in the propellant. The amount of surfactant present is sufficient so that the composition, develops a stable foam upon being dispensed onto a soiled bathroom hard surface. The foam collapses after 10 to 60 seconds to deliver the cleaning components onto the surface.
