Oil dog clippers by placing a few drops on the blade teeth and rear rails, running the motor briefly to spread it, then wiping away the excess.
For the full breakdown, see our best Dog Clippers For Doodles guide.
A dry, dragging blade pulls at your dog’s coat, overheats the metal, and dulls the cutting edge far faster than normal use.
Whether you trim a Doodle’s curly pelt or a terrier’s wiry jacket, the process is nearly identical across brands. Here’s the exact routine, the mistakes that wreck blades, and the few rules worth remembering.
The Standard Oiling Procedure
Clipper oil is a thin, lightweight lubricant designed to seep between the cutter blade and the comb blade. Engine oil, WD-40, or food-grade oils are too thick or too thin for this job, so stick with a product made for clippers.
Follow this sequence for a clean, even coat:
- Turn the clipper off and hold it with the blade tilted downward so oil cannot run back into the motor housing.
- Apply a few drops across the teeth of the top blade —
- Add one drop to each rear rail — the two flat runners on the back of the blade where it rides against the clipper body. Andis’s maintenance guide calls these out explicitly; groomers note that skipping the rails is the most common mistake.
- Run the clipper for about 30 seconds to work the oil into the blade gap and along the moving parts.
- Wipe off the excess with a soft, dry cloth or paper towel. You want a thin film, not a bead of oil — excess oil drips into the coat and can leave your dog smelling like a machine shop.
How Often Should You Oil?
That sounds like a lot, but in practice it means: a few drops at the start, a few more if you’re clipping a thick coat or a second dog, and a final coat before storage so the blades don’t sit dry.
Common Mistakes That Ruin Blades
A heavy bead of oil across the teeth attracts hair and debris, and drips toward the motor.
Also worth knowing: after you wash a blade (with a spray-on blade wash or a quick dip in cleaning solution), the solvent strips the old oil completely. The blade must be re-oiled before the next use; running a clean, dry blade is the fastest way to burn it out. If you’re using an A5-style clipper with a detachable blade, check the manufacturer’s guide for your model — heavier-duty clippers sometimes oil from a different point than light- or medium-duty ones.
Clippers that see weekly use on thick coats will eventually need a replacement blade.
| Step | Where the Oil Goes | Why It Matters |
|---|---|---|
| 1. 3 drops across the teeth | Top blade edge | Lubricates the cutting surface |
| 2. 1 drop on each rear rail | Back of the blade | Keeps the blade sliding smoothly on the clipper body |
| 3. Run for 30 seconds | Spreads the oil into the gap | Ensures even coverage between the blades |
| 4. Wipe off excess | Whole blade surface | Prevents drips on the coat and dust buildup |
| 5. Re-oil after washing | All contact points | Solvent strips oil; a dry blade burns out fast |
Keep the clipper’s air vents clear, store it in a dry spot, and you’ll get years of service out of a blade that cost less than a single trip to the groomer. Andis’s use-and-care instructions cover the specifics for their models, and the routine transfers cleanly to Wahl and other major brands.
FAQs
Can I use vegetable oil or olive oil on clipper blades?
No. Cooking oils are too thick, they turn sticky as they oxidize, and they attract hair and grime.
Why does my clipper get hot even after oiling?
Heat usually means the blade is dull, not dry. A sharp blade cuts hair cleanly; a dull one grinds through it, generating friction. If oiling doesn’t fix the heat, the blade needs sharpening or replacement. Excess oil alone won’t cool a dull edge.
Do cordless clippers need the same oiling routine?
Yes — the blade assembly is identical whether the motor is electric or battery-powered. The only difference is that cordless models have smaller air vents, so be extra careful to hold the blade downward when oiling so nothing drips into the motor.
