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.

Compositions and methods for cleaning automotive surfaces

An apparatus for cleaning an intake system of an engine includes a pressure-resistant container having a reservoir chargeable with an engine cleaner composition and a discharge orifice for discharging the engine cleaner composition from the reservoir. The apparatus also includes a dispensing assembly including an assembly inlet connectable to the discharge orifice of the pressure-resistant container for receiving the engine cleaner composition discharged from the pressure-resistant container. The dispensing assembly further includes an assembly outlet, and a length of tubing for receiving the engine cleaner composition from the dispensing assembly. The apparatus further includes a timer configured to control a timed valve that, when opened, allows the engine cleaner composition to discharge from the pressure-resistant container. The timer is configured to delay opening of the timed valve for a predetermined period of time after actuation of the timer.

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.
