How To Sharpen Paper Shredder Blades

When you invest in a quality shredding machine, you want to ensure that it lasts as long as possible and can stand up to the job you need it to do. When keeping a shredder in working order, you’ll want to understand how to sharpen paper shredder blades, keep them lubricated, and carry out other essential care procedures.

Shredding Oil

Shredding oil is a unique blend of oils that lubricates your shredder blades. Paper dust can cause buildup and dull or clog shredding machines. Shredding oil lubricates the blades to reduce buildup in the cutting assembly, and you should use it after every half hour of shredding time. Be careful to use appropriate products; substituting shredding oil with something like vegetable oil will be detrimental to your machine, as natural and cooking oils can clog shafts and gears and cause the shredder to deteriorate.


An easy way to sharpen shredding machine blades is to run a couple of sheets of aluminum foil through them. Just as foil can sharpen scissors that have dulled, aluminum foil is gentle enough to put into the machine but metallic enough to sharpen those blades. Do this every few weeks to maintain your machine’s sharpness and efficiency.


Both lubrication and sharpening are ways of maintaining a high-capacity industrial paper shredder. Additionally, a large part of upkeep is cleaning the machine. Cleaning the blades and emptying the shredder regularly so that clippings aren’t backing up in the machine are essential ways to keep your shredder running better longer. If you have a lot of shredding to do, give it breaks in between large hauls and run it in reverse occasionally to loosen anything caught between the blades.

Knowing how to sharpen paper shredder blades and maintain them properly is worth the effort. Paper shredders are very useful and help you protect your customers, employees, business, and yourself. Capital Shredder offers NSA-approved shredders and shredding oil. Take care of your products, and they are sure to help you continue the strides you’ve taken toward better security and a more efficient workplace.
