An absorbent article for use in cleaning oil spills comprises a first exposed outer layer of hydrophobic, liquid-permeable, fibrous polymeric nonwoven web and an absorbent body, adjacent the outer layer, comprising oil absorbent, cellulose-based material. Desirably, the article further comprises a second exposed outer layer of hydrophobic polymeric material with the absorbent body disposed between the first and second exposed outer layers. The absorbent article is placed on a layer of oil resting on the surface of a body of water for oil spill clean up. The absorbent article selectively absorbs oil over water because the outer hydrophobic layer repels water but attracts oil and transfers the oil to the oil absorbent body encased between the exposed outer layers. This invention results in considerable savings in cost and in non-renewable resources because the bulk of the product is a cellulose-based material, which is renewable, while only a small portion is polymeric nonwoven, which is non-renewable.

[ We claim:] [1.] Absorbent article comprising a first water repellent, oil absorbent first exposed outer layer formed from a polymer having a surface energy at 20.degree. C. of from about 20 dynes/cm.sup.2 to about 50 dynes/cm.sup.2 wherein the first exposed outer layer is a fibrous polymeric nonwoven web and has an array of discrete surface features wherein the surface features include projections of the nonwoven web extending outwardly from the first exposed outer layer and away from the absorbent body permitting the article to ride lower in water during use; andan absorbent body, adjacent the outer layer, comprising oil absorbent, hydrophilic cellulose-based material, whereby the article is adapted to selectively absorb oil in the presence of water.
