<p>An apparatus for treating an exposed surface. The apparatus has an elongate support with a proximal region and a distal region. The proximal region is engagable by a user to controllably reposition the elongate support and thereby situate the distal region at an exposed surface to be treated. At least one elongate element is provided at the distal region of the elongate support. The at least one elongate element is moveable at the distal region to repeatedly contact an exposed surface at which the elongate element is situated to thereby separate matter from an exposed surface at which the elongate element is situated.</p> |
