The short answer
The short answer
After every groom: take the blade off, brush the hair out along the teeth, wipe it dry, then put one drop of oil on each end of the cutting teeth and one on the rail. Run the clipper for five seconds and wipe the excess off. Three drops, two minutes.
This page is for you if
You own a clipper and want the routine that keeps the blade cutting and keeps it from running hot on your dog.
A clipper blade has two parts that slide against each other: a fixed comb and a moving cutter. Coat, skin oils and dander pack into that interface, and three things follow. The blade cuts worse, because the teeth are partially blocked and the cutter is dragging. It runs hotter, because friction is the heat source in a blade and debris increases friction. And it corrodes, because what is packed in there holds moisture against steel.
The heat is the part that concerns the dog. Blade heat, not motor heat, is what causes clipper burn, and a gummed blade will reach an uncomfortable temperature far faster than a clean one. Cleaning is therefore not housekeeping — it is the cheapest injury prevention available. The clipper burn guide covers the wrist test you should be doing alongside it.
The routine, step by step
01
Take the blade off the clipper
Switch the clipper off and remove the blade. Cleaning a blade while it is on the machine pushes hair and oil into the clipper body, which is where it does the most harm.
02
Brush the teeth out
Brush along the teeth, not across them, working the packed coat out from between the cutter and the comb. Hold the blade teeth-down so debris falls away rather than into the gap.
03
Wipe both surfaces dry
Wipe the cutting surfaces and the back of the blade with a clean dry cloth. Any moisture left on a blade overnight is rust by the morning.
04
Dip or spray if it is gummed
If the blade is sticky rather than just hairy, use a proper blade wash with only the teeth submerged, then run the clipper for a few seconds to clear it and wipe dry immediately.
05
Oil the three points
One drop of clipper oil on each end of the cutting teeth and one along the rail where the cutter slides. Three drops, no more.
06
Run it and wipe the excess
Fit the blade, run the clipper for five seconds to distribute the oil, then wipe off what sits on the surface. Oil left on the outside collects coat and turns into paste.
07
Store it dry
Keep blades in a case or a blade pouch, not loose in a drawer with shears. Chipped teeth come from blades knocking together in storage.
What you are cleaning out: packed coat between the cutter and the comb. This is where both the drag and the heat come from.
Mid-groom, not just afterwards
The after-groom clean keeps the blade alive. The mid-groom one keeps the dog comfortable. Every ten minutes or so, stop, brush the teeth clear, add a drop of oil, and touch the blade to the inside of your own wrist. If it is uncomfortable on you it is worse on the dog — swap to a second blade of the same number if you have one, or use a cooling spray and give it a minute.
On a dense or shedding coat you will be surprised how fast the teeth pack. That is normal and it is also why a clipper that seems to be overheating is very often a blade that needs thirty seconds of attention rather than a machine with a problem.
The three mistakes that ruin blades
Mistake
What happens
Instead
Too much oil
Oil runs onto the dog's coat and collects hair into a paste that packs the teeth faster
Three drops, then wipe the surface
Submerging the whole blade
Solvent gets behind the blade and washes out the lubricant the cutter needs
Teeth only, then dry and re-oil immediately
Putting it away damp
Rust pits the cutting surface, and a pitted blade pulls hair
Wipe dry, oil, store in a case
Clipping a damp coat
Water on steel plus friction equals corrosion, and wet hair dulls an edge quickly
Dry the dog completely first
Clipping through mats
Felted coat forces the cutter out of alignment and chips teeth
Brush or dematt first, or clip shorter underneath
Failure modes of a detachable blade; see the blade size chart page for how the cutter and comb work together.
Never use WD-40, cooking oil or hair clipper lubricant spray as blade oil
Clipper blade oil is a light mineral oil chosen because it does not gum, does not go rancid and is safe against skin. Penetrating sprays strip lubricant rather than provide it; vegetable oils oxidise into varnish; some human clipper sprays are solvents rather than lubricants. Use the oil sold for clipper blades and nothing else.
Clean the clipper too, occasionally
If your clipper has a cooling-fan intake, that intake is also a lint filter, and on a double or curly coat it will pack. Brush the vents out after every few grooms — a blocked intake makes the motor run hot, and motor heat conducts straight into the blade. Clippers with vent-free housings sidestep the problem entirely, which is a large part of why they are the default recommendation for dense coats on the thick-coat roundup.
How long a blade should last
What to remember
→Cleaned and oiled every session, a good A5 blade gives years of home use.
→Neglected, the same blade starts pulling within months — and the dog feels it first.
→A blade that cuts unevenly across its width has a bent or chipped tooth. Replace it.
→A blade that cuts well but runs hot almost always just needs cleaning and oiling.
→Keep a spare of the number you use most. A session interrupted by a bad blade is a session the dog remembers.
The picks in full
Every pick, in order
01
When cleaning no longer helps
Andis UltraEdge detachable blades
The detachable A5 range. A blade is a consumable, and a chipped or worn one is replaced rather than rescued.
There is a point past which a blade cannot be cleaned back into service: a chipped tooth, a cutter worn out of alignment, or a surface pitted by rust will pull hair regardless of how well you oil it. Blades are far cheaper than the clipper and are meant to be replaced. Keeping a spare of your most-used number means a bad blade never ends a session.

What it gets right
+The blade range is the whole reason to own a detachable-blade clipper — any length, bought one at a time
+Fits Andis, Oster A5 and Wahl KM bodies interchangeably
+Finish-cut (FC) and skip-tooth variants of the same number let you choose bite versus smoothness
What it gets wrong
−Each blade is a separate purchase and they add up fast
−Blades dull and need sharpening or replacing — a running cost, not a one-off
−Blade numbers are counter-intuitive: the bigger the number, the shorter the cut
Who should skip itSkip these if your clipper takes a 5-in-1 adjustable blade — they will not fit it.
Most clipper maintenance problems are really air-intake problems: a vented housing pulls coat into the body, the machine runs hot, and the heat reaches the blade. There is no intake here, so cleaning is a blade job rather than a stripdown. On a dense coat that difference shows up within one groom.

What it gets right
+Two usable speeds rather than one compromise speed — 3,400 SPM for bulk removal, 4,400 for finish work
+Takes the whole A5 detachable blade range, so one clipper covers every coat length you will ever need
+The vent-free housing is the reason it survives doodle coats: there is no fan intake for undercoat to pack into
+14 ft cord means you are not fighting an extension lead around a grooming table
What it gets wrong
−Corded, so you work around a cable with a dog that may not stand still
−Ships with one blade; a doodle or double coat needs at least two more, which is a real added cost
−Heavier in the hand than a cordless unit over a long session
Who should skip itSkip it if you own one short-coated small dog — this is more clipper than that coat will ever need.
Snap-on combs that sit over one blade to produce several lengths, so one blade does the work of three.
Clipper attachment combs
Fits
A #30 or #40 blade on an A5 clipper
Range
A graded set of cut lengths from one blade
Material
Stainless steel or molded plastic sets available
Every blade change is an opportunity to drop a blade, chip a tooth or forget to oil. A comb set lets a single #10 or #30 cover a range of body lengths, which concentrates your maintenance on one blade you look after properly rather than five you half-look-after. Combs themselves need nothing more than a wash.

What it gets right
+A cheap way to get many lengths from one blade, which is how most owners should start
+Easier to get an even finish on a fluffy coat than a bare short blade
+Steel sets stay on the blade instead of pinging off mid-stroke
What it gets wrong
−They clog and skip on any coat that is not fully brushed out first
−Plastic sets snap and lose their grip over time
−You cannot get close work — faces and feet still need a bare blade or shears
Who should skip itSkip them if your dog mats between grooms — combs ride over felted coat instead of cutting it.

FAQ
Questions people actually ask
+−How often should you clean dog clipper blades?
Brush the teeth clear and add a drop of oil roughly every ten minutes while you are clipping, and do the full clean-and-oil routine after every groom before the blade goes away. The mid-session attention is for the dog’s comfort; the after-session one is for the blade’s life.
+−What can I use to clean dog clipper blades?
A stiff brush, a dry cloth, and clipper blade oil for the routine clean. For a blade that is gummed rather than hairy, a proper blade wash with only the teeth submerged. Do not use penetrating sprays, cooking oil, or household solvents.
+−How much oil goes on a clipper blade?
Three drops: one at each end of the cutting teeth and one on the rail the cutter slides along. Run the clipper for a few seconds, then wipe the surface. More oil does not lubricate better — it runs into the coat and collects hair.
+−Can I wash clipper blades in water?
Avoid it. Water on a blade means rust unless it is dried and oiled immediately, and rust pits the cutting surface so the blade pulls hair. If a blade has got wet, dry it thoroughly, oil it, and run the clipper briefly to work the oil in.
How this page was put together
We define the coat problem the tool has to solve, shortlist products currently sold, compare the manufacturers’ documented specifications against what that coat actually needs, and cross-check against published findings from named sources. We do not test these tools on our own dogs under controlled conditions, and we will not say we do. Where a figure comes from a manufacturer, we name them; where it comes from someone else’s testing, we cite them. We print no prices — a stale number is worse than none. Read the full method.
