A cleaning composition for cleaning exterior surfaces of a vehicle, said cleaning composition comprising a liquid when applied to said surfaces, said composition having a pH within a neutral range, and consisting essentially of an acrylic acid copolymer, a sulfate of an alkylpolyglucoside surfactant, water, a pH buffer or mixture thereof, a multivalent metal ion, perfume, dye, and a preservative, and wherein said copolymer modifies at least a portion of an exterior surface of a vehicle to render it hydrophilic, providing a contact angle between water and the surface of less than 50°.
A method for cleaning at least a portion of the exterior surface of a vehicle, said method comprising:
- a step of applying a cleaning composition to at least a portion of the exterior surface of a vehicle, said cleaning composition having a pH within a neutral range and consisting essentially of an acrylic acid copolymer, a sulfate of an alkylpolyglucoside surfactant, water, a pH buffer or mixture thereof, a multivalent metal ion, perfume, dye, and a preservative, wherein said copolymer modifies said at least a portion of the exterior surface of the vehicle to render the portion of the surface hydrophilic, providing a contact angle between water and the portion of the surface of less than 50°.
