The soundboard of a grand piano is something you may not think of that needs to be cleaned. Often hard to reach without making scratches on the varnish, which is devastating. Dust and dirt have a negative effect of the sound of your grand piano and can also ruin the varnish on the soundboard. With Sweeper you clean simply by sweeping it over the soundboard. Sweeper can be used by everybody, as well as piano owners and piano technicians. Clean either with the sock moist or dry. Cleans under the iron frame via the holes. Cleans the treble strings (under the bass strings). No scratches on the varnish. A practical loop for hanging up on the wall. The sock is removable and can be washed in a washing machine.
