Oils, particularly petroleum oils may be removed from water, from beaches and from wildlife, by contacting the oils with a collector comprising granular polyurethane particles substantially devoid of cellular structure. Preferably the collector particles are of a jagged, spiny, cragged nature. When applied to an oil contaminant, the collector particles agglomerate the oil into a gel which can be skimmed or otherwise removed easily.
