A cleaning sheet for removing particulate matter from a surface comprises a substrate comprising a first fibrous web comprising carded staple fibers and a reinforcing fibrous web comprising fibers selected from the group consisting of thermal bonded fibers, meltblown fibers, hydroentangled fibers, and spunbonded fibers. The first fibrous web is hydroentangled with the reinforcing fibrous web to form the substrate. The resulting cleaning sheet has a CD elongation of less than about 100% at a load of 500 grams. The cleaning sheet is preferably free of a scrim material and can further comprise an optional additive material. A method of removing particulate matter from a surface comprises contacting the surface with a cleaning sheet of the present invention.
