Having recently brought a new shredder, Its instruction booklet suggests to prolong its life to lubricate it each time you empty the bin. It obviously would like you to use their branded lubricant sheets, as an alternative it suggests applying a bead of vegetable oil to the cutters with a long spouted bottle. Having been told vegetable oil is all that is needed I decided to make my own lubricant sheets.
Step 1: Oily Paper
Fold it in half, and open it out again.
Apply a bead of vegetable oil to the paper just above the fold and close it up.
Feed it to the shredder.
