ABSTRACT:
A three-phase liquid polishing and cleaning composition of the invention is suitable for polishing and cleaning a painted exterior surface, and includes an organic phase, an aqueous phase, and a particulate phase. The organic phase comprises a petroleum-based liquid and the aqueous phase comprises water. The particulate phase comprises at least one particulate polishing grade abrasive having a mean particle size of not more than about 2.5 microns, which is selected from the group consisting of an abrasive that is harder than the painted surface to be polished and cleaned, and an abrasive that is softer than the painted surface to be polished and cleaned. The composition comprises at least one surfactant (e.g., an anionic surfactant, an emulsifying agent, and a foaming agent) to emulsify the organic and aqueous phases upon mixing (e.g., shaking) the composition, and to suspend the particulate phase in the emulsified organic and aqueous phases.
