1. A process for preparing an oil absorbent floor cleaning composition comprising:

  • (a) forming an aqueous reactant phase comprising about 25-70% by weight of abrasive solid particles, about 0.1-5% of the weight of the solid particles of a silane-coupling agent, about 0.1-10% of a nonionic surfactant, about 0.1-20% of a silicone fluid and about 15-40% water;

    (b) mixing said aqueous reactant phase with a water-foamable prepolymer resin which contains at least 2 free isocyanate groups per resin molecule so that the final mole ratio of water to total free isocyanate groups is within the range of about 5-100;

    1, thereby converting said resin into a hydrophilic, open-called, highly reticulated polyurethane foam bun;

    (c) shredding said foam bun; and

    (d) adsorbing an exterior aqueous phase into said shredded foam.
