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 in x 8 in wipes are stored in a "pocket pak" style package with a resealable tab closure to ensure wipes stay moist longer. Ideal for workers to keep on their desks, work stations or tool cribs.
