Abstract:
A gellable vehicle surface cleaning composition is provided that includes a non-ionic surfactant combined with gelling components of an inorganic gel forming substance and at least one water soluble polymer in a ratio of the inorganic gel forming substance to the hydrophilic polymer of between 0.1-1:1. The non-ionic surfactant and the gelling components are provided in an aqueous solvent system. The aqueous solvent system includes a first solvent having a Kamlet-Taft solvent polarity α (K-T α) value of zero, a second solvent having a K-T α 0.6-0.85 value, and water present at more than 50 total weight percent. A process of for cleaning a vehicle surface with a stain is also provided that includes the composition to the stain on the vehicle surface a composition and after allowing sufficient time for the composition to lift the stain, the stain and the composition are removed from the vehicle surface.
