How to Maintain a Paper Shredder? | Keep It Running Smoothly

For the full breakdown, see our best Document Shredders guide.

Paper shredders fail in predictable ways — jammed cutters, dull blades, an overheated motor, or a bin so packed that paper can’t feed through. Most of those problems come from skipping routine care. A few minutes of maintenance every couple of weeks keeps the cutting heads sharp and avoids the frustration of a stalled machine mid-task. Here’s the order that works: empty the bin, clean the blades, lubricate on schedule, and clear jams the right way.

What Does Regular Shredder Maintenance Include?

Regular shredder maintenance boils down to five habits: empty the waste bin before it’s full, remove jammed paper promptly, clear dust and paper buildup from the cutter area, lubricate the cutting mechanism on the manufacturer’s schedule, and keep your hands clear of the feed slot. None of these take more than a few minutes, and together they prevent most breakdowns.

Many modern shredders have indicator lights for a full bin, a jam, or an overheated motor. If your machine has them, don’t ignore them — they’re telling you the exact maintenance step that’s due.

How Often Should You Oil a Paper Shredder?

Lubrication intervals depend on your model, but a good rule of thumb is to oil the blades whenever you empty the bin, or at least twice a month. Some manuals are more specific: one manufacturer’s guide (Fellowes) recommends oiling whenever the bin empties or twice monthly, while a manual for the AS890C model says to oil every month. Check your user manual for the exact interval — it varies.

The oiling sequence for most models:

• Turn the shredder OFF.
• Apply oil in a zigzag line across the paper entry slot (non-aerosol vegetable oil in a long-nozzle bottle works well).
• Run the shredder in reverse for 2–3 seconds (standard models) or 3–5 seconds (per the AS890C manual) to work the oil into the cutters.

If your shredder has a pull-out bin, the sequence differs slightly: turn it off, apply oil across the entry, then hold forward for 2–3 seconds. Lubricant sheets are another option — feed the sheet through, then run reverse for 2–3 seconds. One manufacturer recommends running reverse for about 20 seconds after an oiled sheet to distribute it fully. Use only the oil your manual specifies: fellowes says non-aerosol vegetable oil, while the AS890C manual allows vegetable, cooking, or dedicated shredder oil. Don’t assume all machines take the same lubricant.

Cleaning and Safety: What Not to Do

Before any cleaning, turn the shredder off and unplug it — For blade dust and paper fibers, use compressed air (after unplugging) or wipe gently with a dry lint-free cloth or paper towel. Avoid spray cleaners entirely: one manufacturer warns they can cause a flash fire near the mechanism. Soap and water on a cloth is fine for the exterior; never spray anything into the feed slot.

Safety rules that matter every time:

• Keep the unit at least 4 inches from walls or furniture so the motor can vent heat.
• If the motor overheats, let it cool about 15 minutes (some sources say up to an hour) before testing with a single sheet.
• Never force paper into the slot; feed documents smoothly and in small stacks.
• Keep hands, hair, jewelry, and loose clothing away from the opening.
• Empty the bin at least once a month even if it’s not full.

Jams are the most common frustration. Clear them with reverse/forward cycling: switch to reverse for a few seconds to pull the paper back, then forward again. If the shredder is completely bound, unplug it first, then gently pull the visible paper free. Inspect the power cord during maintenance for wear or damage, per manufacturer guidance.

FAQs

Can I use olive oil or WD-40 to lubricate my shredder?

Stick to what the manual says. Most manufacturers recommend non-aerosol vegetable oil, cooking oil, or dedicated shredder oil. WD-40 is not a lubricant for this purpose, and aerosol sprays risk a flash fire near the motor. Plain vegetable oil from the kitchen, applied sparingly, works on models that allow it.

Why does my shredder smell like burning plastic?

A burning smell usually means the motor is overheated from running too long or the blades are straining on too many sheets at once. Turn it off, unplug it, and let it cool — Then try feeding fewer sheets at a time.

Do I need to empty the shredder bin even if it’s only half full?

Yes. At least once a month, empty the bin regardless of how full it looks. Paper fibers and dust accumulate even in a half-empty bin, and a partially full bin can still block the feed path if paper is sitting at an angle. Regular emptying also gives you a natural cue to lubricate the blades.
