Chapter 03
Studio Prep & Aseptic Technique
A clean tattoo is not an add-on; it is the foundation of the entire procedure. Aseptic technique protects the artist, the client, and the reputation of the studio. This chapter is the operational standard: setup, surface barriers, skin prep, and stencil handling.
Exhaustive Sanitation Protocol
Cross-contamination happens when an unwrapped item touches a used item, when the artist touches non-sterile surfaces with gloved hands, or when aerosols from the machine settle on open work areas. The protocol below is designed to break every possible contamination chain before it forms.
Step-by-Step Setup
- Clean the room first. Remove all clutter. Wipe every work surface with a hospital-grade disinfectant (Cavicide or equivalent) and allow the full wet-contact time - usually 3 minutes - before placing barriers.
- Wash hands. Scrub with antimicrobial soap for at least 20 seconds, clean under nails, and rinse thoroughly. Dry with a disposable paper towel. Use the towel to turn off the tap if it is not sensor-operated.
- Don gloves. Put on a fresh pair of nitrile gloves before touching any sterile supplies. The first pair is your setup pair and is considered clean, not sterile.
- Barrier everything. Cover the workstation, machine, power supply, clip cord, spray bottles, and any item that will be within the procedure zone. Use clear plastic barrier film or disposable sleeves. Every surface the client or artist might touch must be wrapped.
- Open sterile supplies. Needles, cartridges, grips, and inks should be opened only when you are ready to use them. Drop them onto the clean field without dragging packaging across the barrier.
- Change gloves before contact. Put on a fresh pair of gloves after setup and before touching the client's skin.
Barrier Film Placement
Barrier film is the primary defence against contamination. It is not decoration. Apply it tightly to machine bodies, clip cords, and any surface that cannot be sterilised between clients. Replace film between every client, even if it looks clean. Spray bottles that will be used during the procedure must be covered or stored outside the work zone; if they enter the zone, they must be barrier-wrapped and discarded or disinfected after the session.
Cavicide 3-Minute Wet-Contact Rule
Cavicide is a broad-spectrum disinfectant effective against tuberculosis, HIV-1, hepatitis B and C, and many other pathogens. The label specifies a 3-minute wet-contact time for non-porous surfaces. That means the surface must remain visibly wet with the product for three full minutes before it is safe to use. Wiping it dry immediately neutralises the kill time. Track the time with a timer, not by guessing.
| Surface / item | Action | Contact time |
|---|---|---|
| Workstation top | Disinfect, then barrier film | 3 minutes wet |
| Machine and power supply | Barrier film only (do not soak) | Change between clients |
| Clip cord | Barrier sleeve plus disinfectant wipe | 3 minutes wet |
| Client chair / bed | Fresh disposable cover | Change between clients |
| Reusable stainless tools | Ultrasonic clean + autoclave sterilise | Per autoclave cycle |

Skin Preparation
Skin preparation does three things: removes surface oils and dead cells, lowers microbial load, and creates a receptive surface for the stencil. Each step has a specific chemistry and timing.
Green Soap
Green soap is a mild, vegetable-oil-based soap with isopropyl alcohol. It cleans without over-drying. Apply with a clean wipe in a circular motion, then remove with a fresh wipe. Do not reuse the same wipe on a large area. Green soap is for cleaning, not disinfecting; it should be followed by alcohol.
70% Alcohol
Isopropyl alcohol at 70% is more effective than 90% because the extra water slows evaporation and extends contact time with microbes. Apply it after green soap and let the skin air-dry for 30 - 60 seconds. Do not blow on the skin to speed drying; that reintroduces oral flora. Once the alcohol has evaporated, the skin is ready for stencil primer.
Stencil Primer Application
Stencil primer (such as Stencil Stuff or Green Gold) is a thin adhesive layer that bonds the stencil to the skin. Apply a very small amount in a smooth, even layer across the area. Wait until the primer is tacky - usually 30 - 60 seconds - before applying the stencil. If the primer is too wet, the stencil will smudge. If it is too dry, it will not adhere. The correct stage feels slightly sticky but not slippery.
| Step | Product | Dwell / dry time |
|---|---|---|
| Clean | Green soap | Wipe on, wipe off; no dwell |
| Disinfect | 70% isopropyl alcohol | 30 - 60 seconds air dry |
| Adhere | Stencil primer | 30 - 60 seconds until tacky |
Stencil Preservation
A stencil is a map. If it disappears, the artist is tattooing from memory. Preserving the stencil is as important as preserving the line.
The 'Dab, Don't Drag' Wipe Technique
Wiping is the main cause of stencil loss. Dragging a paper towel or gauze across the skin shears the stencil layer and carries pigment across the map. The correct technique is to dab straight down and lift straight up. Use minimal pressure, a clean section of wipe each time, and let the liquid do the work rather than scrubbing.
- Dab: press the wipe gently onto the skin, hold for one second, then lift. Repeat with a clean area of the wipe.
- Pat dry: after dabbing, use a dry wipe to pat the area dry. Do not rub.
- Work in zones: avoid wiping over unstencilled skin back onto stencilled areas. Move from clean to dirty, not the reverse.
- Reapply barrier: a thin layer of Vaseline or aftercare balm over the stencil before tattooing can reduce wipe friction, but it must be applied sparingly to avoid slippery skin.
