Equipment Disinfection Between Treatments – The Full Procedure at OZ Clinic

Written by Shahar Oz, founder of OZ Clinic
The short answer
Every shaving head goes through a cycle of about two hours and ten minutes after each client. Three machines per therapist, 15 minutes of cleaning between clients - and why everything is white.

The short answer: disinfecting equipment between treatments here is not a quick wipe — every shaving head goes through a cycle of about two hours and ten minutes after each client: cleaning, washing, an hour of drying, an hour of disinfection and five minutes of alcohol. That is why each therapist here has three machines — one is physically not enough.

Nobody asks this out loud. But before a treatment in a new place, and especially in an intimate area, the mind asks two questions: has this thing touched someone else? and can I catch something? We would rather answer before being asked, and in full.

The principle behind all of it: disinfect on clean

Disinfectant poured onto a dirty surface works only partly. Grease, skin cells and organic residue reduce its effectiveness. So here we clean before we disinfect, always, and never do it only once.

That also explains a procedure that sounds odd: the room is disinfected at the end of the day, and again at the start of the next one — as though it had never been cleaned. If the evening therapist missed a spot, the morning therapist cleans it without knowing it was there.

What the shaving machine goes through

The full cycle, with no shortcuts, after every client and not at the end of the day:

  1. Removing the hair — with a brush or an initial rinse, so hairs do not lodge between the blades and block cleaning and disinfection
  2. A thorough wash with soap and water from every side — not only for cleanliness, but to remove grease and skin cells that reduce the effectiveness of the disinfectant
  3. An hour of full drying — so the disinfectant arrives at the right concentration and is not diluted by water, and so no moisture is trapped inside the head
  4. An hour of soaking in a high-level disinfectant, of the kind used for reusable medical instruments, according to the manufacturer’s instructions — Gigasept® FF (new), Sekusept® Aktiv or Anioxyde® 1000, or an equivalent product at the same level
  5. Wiping with a paper cloth
  6. Five minutes in alcohol — to remove disinfectant residue, so it does not touch skin
  7. Five more minutes to evaporate, and then back to the treatment room

A cycle of about two hours and ten minutes means you cannot work with one machine. So each therapist has three, and there are always additional new machines in stock. Anyone who would rather we open a brand-new machine for them — we will be glad to.

How do you soak an electric device for an hour

That is the right question to ask, and the answer is simple: only the head is soaked, and the head contains no electronics at all. It is 100% waterproof. The body of the machine, which does not touch the client at all, is rated IPX6.

The blade itself is ceramic, and the head was chosen precisely because it is designed to prevent any possibility of a scratch. In sensitive areas that sometimes matters more than the disinfection itself.

What the laser machine goes through

Immediately at the end of a treatment: an alcohol wipe, then a wipe with water, then medical disinfectant, then alcohol again. The machine is left to stand for five minutes.

And then there is a step we never skip: before the machine touches a client — another spray of alcohol. In case a fly landed on the handle in the meantime. It sounds excessive — and that is exactly why we do it.

The room itself — 15 minutes between treatments

Between every two clients there are fifteen minutes devoted to cleaning alone. The chair is disinfected, the floor is vacuumed and washed with a floor machine, and the sheet is changed.

Those are fifteen minutes we do not sell to anyone. They simply mean fewer treatments a day — and that is exactly the price that turns “we are meticulous” into something you can check.

Why everything is white

That was a decision, not a taste. On white you can see dirt. Dark colours hide stains, hairs and residue. We chose surfaces that cannot hide anything — including from us.

What else is in the room

A disposable fitted sheet, not a roll. It costs more, but it covers the whole chair and does not shift mid-treatment. In a single treatment it is changed twice, because hair from the shaving soils it.

A shower and towels. The client shaves and showers before the treatment, and while they are in the shower the room is refreshed and the sheet changed again. Towels do not wait for the end of the day — the washing machine runs here all day long, so we never reach a pile of waiting towels. The shower is part of the treatment and draws on 15 minutes of the time purchased.

And a supply store that does not run out. We will never reach a point where a therapist has to compromise in the middle of a day.

Why it matters especially in the intimate area

In a treatment on the groin, the testicles or the buttock line there is one question most people do not ask out loud. The answer is everything written above — and we would rather answer it before being asked.

What counts as standard — and where exactly we sit

In the accepted infection-control classification, a device that touches intact skin is considered a non-critical device, and the requirement for it is far lower than for invasive instruments. A high-level agent belongs to the class above that. We chose the higher class because shaving can create a tiny scratch, and we would rather not rely on it not happening.

The same logic applies to everything else. A roll sheet is cheaper than a fitted one and meets the requirement; 15 minutes of cleaning between clients is nobody’s requirement; and no law obliges a shower or a towel. All of these are a choice, and each one costs money. That is exactly what makes them something you can check rather than only be promised.

The standard we work to

Zero wounds, zero infections. That is not a slogan — it is the number every procedure here is built around, including what we ask of you before and after a treatment.

Questions that keep coming up

Has the head you shave me with touched someone else?

Not before it has been through the whole cycle — cleaning, washing, an hour of drying, an hour of disinfection, five minutes of alcohol and evaporation. A cycle of about two hours and ten minutes. And if you would rather have a brand-new machine — we will open one for you.

Can I bring my own shaving machine?

Absolutely. And you can also buy one here — it is the same machine we work with.

What happens if the day is too busy?

That is exactly why there are three machines per therapist and additional stock. The cycle does not get shorter when the diary is full; the number of machines is what adapts.

Why is the room disinfected both at the end of the day and in the morning?

So that human error changes nothing. If a spot was missed in the evening, the morning deals with it — without knowing it exists.
