How do you sharpen a paper shredder?

To sharpen a paper shredder, you can use specialized shredder lubricant sheets or oil, which help maintain the blades' efficiency. Simply feed a lubrication sheet or a small amount of shredder oil into the machine as you would regular paper, allowing it to process the material. This helps to clean and lubricate the blades, preventing them from becoming dull. Regular maintenance will extend the life of your shredder and ensure optimal performance.
