Perfect for cleaning rubber respirator facepieces and other personal safety equipment, these pre-moistened wipes contain Benzalkonium Chloride (BZK), ideally suited for when the manufacturer recommends using a non-alcohol cleaning wipe. These large 5″ x 8″ wipes are stored in individual pocket paks inside a dispenser box (20 pocket paks per dispenser box). The dispenser box is perfect for communal work areas where workers can grab a Pocket Pak quickly and easily.
