Do You Need To Oil Foil Shaver

Yes, you absolutely need to oil your Foil Shaver regularly.

The working principle of a reciprocating shaver is essentially high-speed “metal-to-metal” friction. If there is a lack of that thin lubricating oil film, under that extremely thin knife net, the high-speed reciprocating blade will generate huge heat. The result? So-called “knife net burn” (foil burn), hair pulling, and premature wear of the cutter head.

For new machines that have just started, I usually recommend following this frequency: if you are dry shaving, then each cutter head should drop at least 1 drop of light mineral oil every week (that is, our common electric clipper oil); If you are used to washing shavers with water, you must oil them after each use. Soap and water will instantly wash off the grease from the factory.

Why ‘Metal On Metal’ Friction Is The Biggest Enemy

Under the razor’s knife net, the cutting block is oscillating back and forth at thousands of RPM (revolutions per minute). This is real high-speed metal friction. Without the lubricant as a barrier, this friction immediately has two bad consequences:

• Overheating: The blade heats up extremely fast. If you feel the knife net on your face in the middle of shaving, this is the most obvious sign of excessive friction and lack of oil.
• Knife net burns: As the metal heats up, it will expand microscopically and increase resistance, causing skin irritation, which is what we often call “knife net burns”.

The Cost Of Neglect Of Maintenance

If you ignore the oiling step, the consequences will not only be as simple as the machine getting hot. The real trouble is the physical damage to the cutting components:

• Premature wear: The knife net of the reciprocating razor is made very thin for the veneer effect. An unlubricated blade will quickly wear the inner surface of the knife net like sandpaper. Before long, you will find that the knife net has a hole-this will directly scratch the skin.
• Pulling hair: When the friction increases, the cutting efficiency of the blade will be greatly reduced. Dry, labyrinthine blades no longer “cut” beards cleanly, but are easier to “hook” and pull them.

When To Oil: Dry Scraping Vs. Wet Cleaning

If You’re Mainly Dry Scraping

If you usually only use a brush to clean broken hair, the lubricating oil at the factory will stay on the blade for a long time. In this case, the oil once a week is enough to replenish the lubricating layer.

If You Rinse With Water

Many people are used to washing their razors under the tap and then forget about it. Water and soap will thoroughly strip all lubricants. If you clean with water, you are leaving the internal metal components in a completely dry state, which is extremely vulnerable to corrosion and friction. Therefore, as long as you use water, you must add oil after the end.

How To Properly Oil

Oil is not a “bath” for the machine, don’t pour too much. Our goal is to form an “extremely thin lubricant film”.

Use light mineral oil: Use only special electric clipper oil or light mineral oil. Never use those heavy fats or vegetable oils, they will only stick to the mechanical structure and spoil the machine.

1 drop principle: each knife net head only needs 1 drop.

Power distribution: After dripping, turn on the shaver and idle for 5 to 10 seconds. Let the oscillating blade spread that 1 drop of oil evenly over the entire cutting module.

Long-Term Benefits: Battery Life And Sharpness

Adhering to this “10-second habit”, the rewards in electronic components and mechanical structures are huge:

• Reduce motor load: A well-lubricated shaver has less resistance. The motor does not need to work hard to drive the cutter head, which directly translates into longer battery life.
• Extend blade life: By minimizing the grinding effect of friction, your blades can stay sharp for several months longer than they would be in a dry state.
• Smoother touch: Finally, the microscopic oil film helps the knife net move smoothly across the skin, ensuring that you get what the device is designed to promise-a comfortable, non-irritating shaving experience.
