Barrier Milk Ready-To-Use Spray helps prevent corrosion of instruments when used prior to sterilization. This pre-cleaning spray is specially formulated for use on dental and surgical instruments, hinged instruments, bur blocks and general equipment. It lubricates and maintains the smooth working of hinged instruments and the phenol-free formula is safe for use on ferrous and non-ferrous metal as well as resin instruments. When used regularly, Barrier Milk Spray protects instruments from rust and corrosion due to over exposure to steam in the autoclave. This extends the life of instruments while keeping them looking new in appearance.
