Swingline shredder oil is specifically designed to lubricate the cutters in your shredder. Swingline oil is synthetic and will not cause build-up on any shredder parts. The cutters of a well-oiled shredder require less torque to shred effectively. As a result, the cutters move freely and easily to power through the maximum document capacity of any particular shredder model. Protect your investment and extend the life of your shredder with regular use of Swingline shredder oil.
