THIS IS IT! This record cleaning brush and liquid spray cleaner actually does what it is advertised to do. The very fine bristles, though soft, fully removed all the dirt and dust in and outside the grooves. Though I generally take care of my albums, the brush and cleaner produced an added level of clean. The proof was in the before and after sound of my music. With the record spinning on the platter after just 3 spot sprays allowed the handheld brush to effectively do its job. Only 30 seconds of holding the brush (not heavy handed), while moving it back and forth toward the center gets the grooves clean. WORTH IT!
