An automotive surface is cleaned by applying an effective amount of a cleaning composition comprising a) at least one hydrocarbon solvent in an amount from about 3 weight percent to about 20 weight percent of the composition, b) at least one thickener/rheology modifier in an amount from about 0.01 weight percent to about 3 weight percent, c) at least one silicone fluid has a viscosity ranging from about 500 to about 20,000 centistokes at 25° C., present in an amount from about 0.1 weight percent to about 3 weight percent, d) at least one wetting agent in an amount from about 0.001 to about 2%, e) at least one hydrophobic additive in an amount from about 0.1 to about 3%, and f) water in an amount from about 60 weight percent to about 85 weight percent to the automotive surface with an application implement.

A polycarbonate headlight lens cleaning and restoring kit has a lens cleaning composition, an applicator wipe; and a lens restoring composition comprising a coating component. The polycarbonate cleaning composition contains only liquid components and is free of water. The cleaning composition has a first solvent that softens a Control Polycarbonate Substrate and has a flash point of from &#x2212;58 F to 220 F; and a second solvent that does not soften a Control Polycarbonate Substrate. The first solvent and the second solvent are present in an amount effective to substantially remove discoloring contaminants from a polycarbonate headlight lens and the polycarbonate lens, and also in an amount so that, after removal of the discoloring contaminants, the polycarbonate headlight lens can be restored to a clear condition. A method of cleaning and restoring a polycarbonate headlight lens that is at least partially discolored from discoloring contaminants is also provided.
