ideal shredder oil is a specially blended, non-toxic, high-cling, non-detergent oil formulated exclusively for ideal shredders. It is recommended that shredder blades be oiled for every 30 minutes of operation for cross-cut shredders, and for every hour of operation for strip-cut models. Oil helps your shredder run smoother, faster, and quieter, and puts less strain on the motor, gears, and bearings.
