A method for cleaning a substrate is provided. The method includes providing foam to a surface of the substrate, brush scrubbing the surface of the substrate, providing pressure to the foam, and channeling the pressured foam to produce jammed foam, the channeling including channeling the pressured foam into a gap, the gap being defined by a space between a surface of a brush enclosure and the surface of the substrate. The brush scrubbing of the surface of the substrate and the channeling of the pressured foam across the surface of the substrate facilitate particle removal from the surface of the substrate.
