There is a special kind of pain in watching an expensive clipper slow down. Before you throw it in a drawer and order another one, know that most “dying” clippers are just filthy inside, and the fix costs less than twenty dollars in supplies. We watched a full teardown-and-refurb of a slow Wahl Senior, and the gunk that came out of it explained everything. We cover the consumables worth owning, what each one actually does, and the teardown order that brings a tired clipper back to new.
Key Takeaways
- Most slow clippers are clogged, not broken: hair packed around the lever and blade pin kills speed and travel.
- The four supplies that cover 90% of maintenance: clipper oil, a 5-in-1 coolant spray, blade wash for baths, and Barbicide for disinfecting.
- Oil after every cut; a blade bath only when the blade is gummed; Cool Care between every client.
- Deep cleaning means pulling the blade and lever: hair packs inside where spray never reaches.
- Reassembly matters: lever screws slightly less than hand-tight, and the bottom blade set just forward of the top blade unless you are zero-gapping.

Watch a Slow Clipper Come Back to Life
In the video above, The One Minute Barber refurbishes a Wahl Senior that had started failing. Watch the blade bath alone: one bath is not enough, and the second bath still flushes out cut hair. Then he pulls three screws, slides the housing off, and finds hair packed so deep the blade’s rotating pin is invisible. That is what “my clippers are dying” usually means.
The Four Supplies That Matter
Clipper oil. The cheapest and most important consumable you own. Two drops on the left corner of the blade, two on the right, one in the middle, run it for a few seconds, wipe. It reduces friction, heat and rust, and skipping it is the number one reason blades get dull and hot. The Wahl Premium Blade Oil, 4 oz; one bottle lasts a working barber most of a year. Our how-often-to-oil guide covers the full routine.
A 5-in-1 coolant spray. This is the between-clients tool: it cools, cleans, lubricates, disinfects and prevents rust in one spray, and the high-pressure nozzle blasts hair out of the blade teeth without removing the blade. The Andis Cool Care Plus, 15.5 oz is the standard. Spray the blade while it runs, let it sit moist for ten minutes, let it air dry.
Blade wash for baths. When a blade is gummed with product and hair, spray is not enough. Fill a small tub with blade wash, run the blade in it, and watch what comes out. In the video, the technician gives the blade two baths and still finds gunk inside, which is why the teardown step below exists. The Wahl Professional Blade Ice, 14 oz doubles as a coolant spray and wash-style cleaner and is safe on plastics.
Barbicide. Cool Care disinfects blades; Barbicide disinfects everything that touches skin, from combs to guards to clipper housings. Mix 1 part concentrate to 16 parts water, immerse for ten minutes, rinse and dry. The Barbicide Concentrate pint.99 and lasts a small shop months. We have a full Barbicide mixing and contact-time guide and a step-by-step clipper disinfecting walkthrough.
The Teardown That Saves a Slow Clipper
The routine from the video, in order. First, brush all loose hair off the clipper body and blade. Second, spray around the blade with your 5-in-1 or clipper spray to lubricate and loosen. Third, the bath: blade wash, blade running, until the fluid runs clean, twice. Fourth, remove the blade’s two screws and lift it off, then the lever’s screw and the lever slide. Fifth, open the housing (three screws on the back, the lid is clipped on, so pry gently with a plastic tool, not a screwdriver) and look inside. In the video, hair is packed around the switch and the blade’s rotating pin is completely buried.
Clean the inside with the pointed end of the blade brush, blast it out with a hair dryer, and scrape the gunk off the housing’s sealing edge so the lid reseals and hair stays out. Then reassemble: spring in first, housing slides into the top lip, moving blade on, lever slide back in. Screw the blade in loosely, and set the lever screw slightly less than hand-tight, because you still need to move the lever when you line up the blades. With the lever up, set the bottom blade just slightly forward of the top blade, about half a millimeter, unless you are zero-gapping, in which case align them almost perfectly. The video’s Senior came back cutting like new without a single part replaced.

FAQ
My clipper is slow and hot. Is it broken?
Probably not. It is almost certainly packed with hair inside the lever housing and around the blade pin. Do the teardown above before you spend money on a replacement.
Can I use Cool Care Plus instead of oil?
It lubricates, but it is a spray, not a precision oil. Use Cool Care between clients and real oil after each cut. They are not substitutes.
Can I wash clipper blades with water?
No. Water causes rust. Use blade wash or Blade Ice, then dry the blade completely and oil it.
How long does Barbicide mixed solution last?
Once mixed, the working solution should be changed daily, or sooner if it is visibly cloudy or dirty. The concentrate itself keeps for years.
