How to Clean and Oil Hair Clippers: The 5-Point Pro Method

Want sharp blades every time? Learn how to clean and oil hair clippers in under 5 minutes. Our expert guide covers the best tools and professional techniques.

Let’s be real for a second: Most guys treat their hair clippers like a disposable razor. They use them until the blades get hot, the motor starts screaming, and the teeth start pulling hair like a medieval torture device. Then, they throw them away and buy a new pair.

That is a rookie mistake.

If you know how to clean and oil hair clippers properly, a $60 pair of Wahls can last you a decade. If you don’t, even a $200 pair of professional Babyliss GoldFX will be junk in six months.

At MenReviewHub, we’ve tested every major trimmer on the market. Here is the no-nonsense, pro-grade routine to keep your blades sharp, your motor cool, and your skin irritation-free.

Phase 1: How to Clean Hair Clippers (The “Deep Scrub”)

Most guys think “cleaning” means blowing on the blades and calling it a day. Wrong. If you want your clippers to cut like butter for five years instead of five months, you need to get rid of the “hair jungle” hiding inside.

Here is the professional 3-step protocol for a true deep clean.

Step 1: The Dry Brush (Clear the “Hair Jungle”)

Before you add any liquids, you must remove the physical debris. Hair, dead skin, and scalp oils act like a sponge for bacteria.

• The Move: Turn the clipper OFF. Use your stiff cleaning brush to sweep out the hair trapped between the teeth and around the taper lever.

• Pro Tip: Don’t forget (the hair trap)—that little gap behind the blades where the motor arm sits. If hair builds up here, it puts massive strain on the motor, leading to that loud “grinding” sound you hate.

Step 2: The Disinfectant Blast (The “Cool Down”)

This is where you kill the germs and cool the steel. If you’ve ever had “barber’s itch” (folliculitis) after a trim, it’s because of dirty blades.

• The Move: Turn the clipper ON. While the blades are moving, spray Andis Cool Care Plus or Wahl Clini-Clip directly onto the teeth.

• Why Running? The high-speed vibration forces the disinfectant deep into the microscopic gaps between the moving and stationary blades, flushing out gunk you can’t see.

• Wait: Let the spray sit for 2 minutes. Most disinfectants need “contact time” to actually kill 99.9% of bacteria.

Step 3: The Monthly “Under the Hood” Deep Dive

Once a month (or every two weeks if you’re a heavy user), you need to perform surgery.

• The Move: Grab a small screwdriver and remove the two screws holding the stationary blade.

• The Reveal: You’ll likely find a solid “brick” of hair inside the motor housing. Clear it out completely.

• The Re-alignment: When putting the blades back, ensure the top blade is roughly 1/32 to 1/16 of an inch behind the bottom blade. If they are perfectly flush, you will “zero-gap” yourself—and that means a trip to the ER for a nasty skin cut.

The “Smell Test” for Dirty Clippers

If your clippers smell like “old gym socks” or burnt hair, they are infested with bacteria and old oil. Do not use them on your face. Perform the Deep Scrub immediately.

Phase 2: How to Oil Hair Clippers (The 5-Point Method)

If you skip oiling, you are essentially running two pieces of industrial-grade sandpaper together at 7,000 RPMs. Friction creates heat, heat dulls the steel, and a dull blade forces the motor to work twice as hard. Eventually, the motor burns out, and you’re left with a $100 paperweight.

At MenReviewHub, we use the 5-Point Method. It ensures 100% lubrication coverage without creating a greasy “sludge” that traps hair.

The Step-by-Step Execution:

1. Turn the Clipper ON: This is non-negotiable. You need the blades moving so the oil can migrate across the entire surface through capillary action.

2. Point 1, 2, & 3 (The Teeth): Apply one drop of Wahl Clipper Oil on the far left corner, one in the dead center, and one on the far right corner of the blade teeth.

3. Point 4 & 5 (The Heels): Look at where the moving top blade meets the stationary bottom blade on the sides. Apply one drop to each “heel” or side rail. This is where the most friction occurs, and it’s the part most amateurs forget.

4. The “Lever Workout”: While the motor is running, rapidly toggle your taper lever (the handle on the side) up and down for 10–15 seconds. This forces the oil into every microscopic groove of the blade assembly.

5. The Wipe (Crucial Step): Turn the machine off. Use your microfiber cloth to wipe away any excess oil from the blades.

   • Expert Tip: You want a microscopic film of oil, not a wet surface. If the blades look “drippy,” hair will stick to them immediately, creating a “sandpaper paste” that will dull your blades faster than no oil at all.

The “Sound Test”: How to Tell if You Need More Oil

An American barber can tell if a clipper needs oil just by listening.

• The “Angry” Buzz: If your clippers sound high-pitched, metallic, or “rattly,” they are bone-dry.

• The “Smooth” Purr: After following the 5-Point Method, your clippers should have a deep, consistent hum. If the sound changes the second you add oil, you waited too long.

Can You Over-Oil?

Yes. If you use too much oil, it can seep past the blade seal and into the motor housing. Over time, this coats the motor in a sticky grime that causes overheating. Stick to the 5-drop rule. It’s all you need.

The “Home Barber” Secret: If you only use your clippers once a week, oil them before you put them away. Most clipper blades are made of high-carbon steel, which can rust if exposed to the humidity in your bathroom. A thin layer of clipper oil acts as a rust-proof barrier.

When to Perform Maintenance? (The Schedule for Success)

1. The “Home Barber” (Once-a-Week Trimmer)

If you’re just cleaning up your fade or trimming your beard every Saturday morning, you don’t need to do a full teardown every day. However, you should never put your clippers away “dirty.”

• Dry Brush: After every single use.

• Disinfectant Spray: After every single use.

• 5-Point Oiling: Before you put them back in the drawer.

• Why? Bathroom humidity is the #1 cause of rust. A fresh coat of Wahl Clipper Oil acts as a waterproof seal while the tool sits idle.

2. The “Heavy User” (The 3-Day Rotation)

If you’re the guy who cuts your own hair, your kid’s hair, and your neighbor’s beard, you’re putting high mileage on those blades.

• Deep Clean (Phase 1): Every 2 weeks.

• Oiling: Every time you turn the machine on.

• The “Heat Check”: If you’re cutting for more than 15 minutes straight, hit the blades with Andis Cool Care Plus halfway through to prevent thermal expansion (which dulls blades instantly).

3. The “Pro Barber” (Back-to-Back Clients)

If you’re a professional in the US, you know the State Board doesn’t play games.

• Disinfectant Spray: Between every client. No exceptions.

• Oiling: At least twice a day (once at the start of your shift, once at lunch).

• Deep Scrub: Every Friday night. Remove the blades, clear the internal (hair trap), and recalibrate.

The “Red Flags”: Signs You Needed Maintenance Yesterday

Sometimes the calendar doesn’t matter. If your clippers exhibit any of the following symptoms, stop what you’re doing and perform the 5-Point Method immediately:

• The “Yank”: If the clipper starts “snagging” or pulling hair instead of slicing it, the blades are dry and lack the lubrication to slide past each other.

• The “Hot Flash”: If the metal blades feel uncomfortably warm against your skin after only 2 minutes of use, the friction levels are dangerous.

• The “Grind”: If the motor sounds “heavy” or makes a high-pitched grinding noise, the internal friction is killing your battery and motor.

• The “Tattoo”: If the clipper leaves red, irritated tracks on your neck, the blades are likely dirty and harbor bacteria.

Common Mistakes to Avoid

Maintenance is simple, but it’s also easy to mess up if you’re rushing. Here are the top mistakes I see at MenReviewHub that lead to dead motors and rusty blades.

1. The “WD-40” Disaster

I see this suggested all the time: “Just spray some WD-40 on it!” Don’t do it. WD-40 is a solvent designed to remove grease and break up rust; it is not a long-term lubricant for high-speed machinery. It will strip away the actual clipper oil and leave your blades bone-dry within minutes, causing them to overheat and seize.

2. The “Kitchen Cabinet” Substitute

Vegetable oil, olive oil, and coconut oil are great for your beard or your salad—but they are a death sentence for clippers. These oils are organic and will eventually go rancid. They turn into a sticky, gummy “goop” that clogs the motor and attracts bacteria. Stick to professional mineral oil.

3. Oiling “Dirty” Blades

If you haven’t used your cleaning brush to remove the hair first, adding oil is a mistake. The oil mixes with the tiny hair clippings to create an abrasive “grinding paste.” Instead of lubricating the blades, you’re essentially sanding them down every time they move. Always brush first, oil second.

4. The “Water Wash”

Unless your clippers are specifically labeled as “100% Waterproof” (like some multigroomers), keep them away from the faucet. Even a few drops of water inside the motor housing can cause a short circuit or start the oxidation (rust) process on high-carbon steel blades. If you need to “wash” them, use a disinfectant spray instead.

5. Over-Oiling the Machine

More is not better. If oil is dripping down the side of the clippers or onto your hand, you’ve used too much. Excess oil can seep into the internal motor and coat the electronics, leading to overheating or a total burnout. Follow the 5-Point Method and always wipe off the excess with a microfiber cloth.

6. Ignoring the Taper Lever

That little handle on the side of your Wahls or Andis clippers controls the blade gap. If you don’t put a tiny drop of oil on the lever’s hinge occasionally, it will become stiff and eventually snap off. A smooth lever is the sign of a well-maintained tool.

The Expert’s Bottom Line: Your clippers are a precision instrument, not a hammer. Treat them with a little respect, use the right maintenance products, and they will reward you with clean lines and zero “yank” for years to come.
