Abstract
This invention relates to a method for removing liquid contaminant from surfaces, especially for removing spilled oil from the surface of water. More particularly, this invention relates to a method for removing liquid contaminant from a surface by applying a mat which is a nonwoven fabric having a dried substantially continuous aqueous foam coating on at least one side of the nonwoven fabric, whereby the foam coating absorbs at least some of the liquid contaminant. This invention also relates to a reusable mat for removing liquid contaminants from surfaces and a method for reusing the mat.
