Salon Hygiene: Sanitising vs Disinfecting vs Sterilising (2026 Guide)
Quick answer: Sanitising reduces the germs left on a surface after cleaning. Disinfecting kills most harmful germs on surfaces and tools, but not bacterial spores. Sterilising destroys all forms of microbial life, including spores. In a salon, clean, disinfect and dry every reusable tool between clients; sterilise metal implements that can cut skin or touch blood (for example in an autoclave); and throw away single-use items after one client.
Clients notice hygiene before they notice your interiors. A comb pulled from a dirty drawer or a foot spa that smells stale can lose a client for life, and poor practice can spread fungal, bacterial and viral infections between people. This guide clears up the confusion around salon hygiene: sanitising vs disinfecting vs sterilising, and turns it into routines your team can follow every day in a hair salon, beauty parlour, nail studio or spa.
Cleaning, sanitising, disinfecting and sterilising: clear definitions
These words are often used as if they mean the same thing. They do not. Each one is a different level of germ removal, and each has a place in your salon. The definitions below follow guidance from the US Centers for Disease Control and Prevention (CDC), which is widely used as a reference for infection control.
Cleaning
Cleaning is the removal of visible dirt, hair, product build-up and other organic and inorganic material from tools and surfaces, usually with soap or detergent and water and a brush or cloth. Cleaning with soap or detergent also lowers the number of germs. It is always the first step, because dirt and residue stop sanitisers and disinfectants from working properly.
Sanitising
Sanitising reduces the remaining germs on a surface after cleaning to a lower, safer level. In everyday salon language, “sanitation” also means the general practice of keeping the salon clean: sweeping up hair and nail clippings, washing hands often, using clean uniforms and towels, and never leaving used tools lying around. Hand sanitiser is a form of sanitising for skin.
Disinfecting
Disinfecting uses chemicals to kill harmful germs that remain on non-living surfaces and tools after cleaning. The CDC describes disinfection as eliminating many or all disease-causing microorganisms on objects, except bacterial spores. Not every disinfectant works on every germ, and a disinfectant only works if the surface stays wet for the full “contact time” printed on the label.
Sterilising
Sterilising destroys or eliminates all forms of microbial life, including bacterial spores. It is done with physical or chemical methods, most commonly steam under pressure in an autoclave. It is the highest level, and the one needed for instruments that may break the skin or come into contact with blood.

Which salon tool or surface needs which method?
Hospitals use a simple risk rule called the Spaulding classification, and it works well for salons too. The CDC describes three groups: critical items carry a high infection risk if contaminated and need sterilisation; semi-critical items touch mucous membranes or broken skin and need at least high-level disinfection; non-critical items touch only intact skin and need low-level disinfection. Translated to a salon:
| Item | Risk | Method between clients |
|---|---|---|
| Cuticle nippers, pushers, metal files, tweezers, comedone extractors, scissors used for nail work | Can break the skin or contact blood | Clean, then sterilise (autoclave), store in a sealed pouch |
| Razors and blades, lancets, needles | Contact with blood | Single-use: new blade for every client, dispose in a sharps container |
| Combs, brushes, sectioning clips, rollers, hair scissors | Intact skin and hair | Clean, disinfect, dry |
| Clipper and trimmer blades | Intact skin, small nicks possible | Brush off hair, clean, spray or dip with a disinfectant suitable for electrical tools, dry; sterilise detachable blades if they contacted blood |
| Facial brushes, makeup brushes, eyelash tools | Face, eyes, skin | Clean and disinfect after every client; use disposable applicators where possible |
| Emery boards, buffers, pumice stones, orange sticks, wax spatulas, cotton, sponges | Porous, cannot be disinfected | Single-use: give to the client or throw away; never double-dip wax spatulas |
| Pedicure tubs and foot spas | Water, skin, fungal risk | Drain, scrub, rinse, fill with disinfectant for the label contact time after every client; deep clean daily |
| Styling chairs, shampoo basins, facial and massage beds, trolleys, stations | Intact skin | Clean and disinfect between clients; fresh couch roll or cover each time |
| Reception desk, card machine, door handles, washrooms | High-touch | Clean and sanitise or disinfect several times a day |
Step-by-step routine for reusable tools
Remove hair and debris
Wear gloves. Brush off hair, nail dust and product from the tool straight after the service, at the station or back bar.
Wash with soap or detergent
Scrub with a small brush in warm, soapy water, paying attention to hinges, teeth and serrated edges. Rinse in clean water.
Dry
Pat dry with a clean towel or paper towel, so water does not dilute the disinfectant.
Disinfect for the full contact time
Fully immerse the tool in a properly diluted, registered disinfectant (or spray electrical tools until visibly wet) and leave it for the full contact time stated on the label. Do not take tools out early. Change the solution as the label instructs, and sooner if it looks cloudy or has hair in it.
Sterilise if needed
For instruments that can cut skin or contact blood, place the clean, dry tools in sterilisation pouches and run them through the autoclave (see below) instead of, or after, chemical disinfection.
Rinse, dry and store clean
Rinse if the label asks, dry fully, and store in a clean, closed, labelled container or drawer, kept separate from used tools. Mark containers “Clean” and “Used” so they never get mixed up.
Autoclave, UV cabinets and other equipment
Autoclave (steam steriliser)
An autoclave sterilises with steam under pressure. CDC guidance gives minimum exposure times for wrapped items of 30 minutes at 121°C in a gravity-displacement steriliser and 4 minutes at 132°C in a pre-vacuum steriliser; your machine’s manual will specify the exact cycle, which also includes heat-up and drying time.
- Clean and dry tools before loading; an autoclave does not remove dirt.
- Open hinged tools and do not overload the chamber, so steam reaches every surface.
- Use pouches with chemical indicators that change colour when the cycle conditions are met.
- Keep a simple log of date, cycle and operator, and arrange periodic spore (biological indicator) testing as the manufacturer recommends.
- Keep pouches sealed until you open them in front of the client; this is also a strong trust signal.
UV “steriliser” cabinets
Many salons use UV boxes, but they should not be treated as a way to disinfect or sterilise dirty tools. UV light only reaches surfaces it shines on directly, and shadows, hinges and residue block it. California’s Board of Barbering and Cosmetology, for example, does not recognise UV units as an approved method of disinfecting soiled tools. Use a UV cabinet, if you have one, only as a clean storage box for tools that have already been cleaned and disinfected.
Glass bead sterilisers and disinfectant jars
Hot glass bead units heat only the tip of a tool and are not a substitute for an autoclave. Disinfectant jars are useful for immersion, but only for tools that have been cleaned first, and only with fresh solution at the correct dilution.
Surfaces, furniture, floors and linen
- Between clients: clean and disinfect chairs, headrests, armrests, shampoo basins, beds, trolleys and stations. Replace couch roll or covers every time.
- Chairs and upholstery: most salon chairs are PVC or vinyl. Use a disinfectant the chair manufacturer approves, because harsh products, including some alcohol-based ones, can dry and crack the surface over time. A cracked surface cannot be disinfected properly, so repair or replace it.
- Floors: sweep hair and nail clippings immediately after each service to prevent slips and the spread of germs; mop thoroughly at closing.
- Towels, gowns and capes: use a fresh towel for every client, store used linen in a closed bin, and wash in hot water with detergent. Damp, used towels left lying around look bad and grow germs.
- Washrooms and pantry: clean several times a day, with soap, paper towels or a hand dryer, and a covered bin.
- Ventilation: keep air moving with windows, exhausts or air-conditioning with clean filters, especially where colour, keratin, acrylics and nail products are used.
Daily and weekly salon hygiene checklist
- Disinfect stations, chairs, basins and beds
- Fresh disinfectant solution in jars
- Clean tool sets ready, autoclave pouches sealed
- Hand soap, sanitiser, paper towels and gloves stocked
- Washrooms checked
- Hands washed or sanitised
- Tools cleaned, disinfected or sterilised
- Single-use items thrown away
- Chair, basin or bed disinfected; fresh towel and cover
- Hair and clippings swept up

Assign every task to a named person on a visible rota and record who did it and when. Shared responsibility without names usually means nobody does it.
Staff hygiene and practices
- Hand hygiene: wash hands with soap and water when visibly dirty, after the washroom and after eating. The WHO technique takes 40–60 seconds. Between clients, an alcohol-based hand rub (20–30 seconds) works when hands are not visibly dirty.
- Gloves: use disposable gloves for waxing, nail work, facials with extractions, chemical services and cleaning; change them between clients and wash hands after removing them.
- Uniforms and nails: clean uniforms daily, short clean nails, hair tied back, no hair or nail dust on clothes.
- Stay home when unwell: make it clear that staff with a fever, infection or contagious illness should not work with clients, and support them when they do the right thing.
- Training: train every new joiner on this routine and refresh the whole team regularly.
What to do if there is a cut or blood
Stop the service and protect yourself
Put on gloves if you are not already wearing them. Give the client clean cotton or gauze to apply pressure, or apply it yourself.
Treat and cover the cut
Clean the area with an antiseptic and cover it with a sterile dressing or bandage. If bleeding does not stop or the cut is deep, advise the client to seek medical care.
Deal with contaminated items
Throw blood-soiled single-use items and blades into a closed bag or sharps container. Clean and sterilise any reusable tool that touched blood. Clean and disinfect the work surface.
Record it
Note the incident, what was done and who handled it. Review whether a tool, technique or training gap caused it.
If a client arrives with a visible skin, scalp or nail infection in the area you would treat, it is usually wiser not to perform the service. Explain politely and privately, suggest they check with a doctor first, and offer to rebook. This protects them, your team and your other clients.
Turn hygiene into client trust
Good hygiene only builds trust when clients can see it. Make your standards visible without making the salon feel like a clinic:
- Open sealed sterilised pouches in front of the client.
- Use fresh towels, capes and couch roll visibly, every time.
- Display a short hygiene promise at reception and on your booking page and Google Business Profile.
- Share short videos of your cleaning routine on Instagram and WhatsApp status.
- Leave enough time between appointments for proper cleaning, instead of rushing the next client in.
- Ask for feedback after each visit and act quickly on any hygiene complaint.
Clients who feel safe come back and recommend you, which is why hygiene belongs in your customer experience plan, not just your cleaning rota.
How salon software supports hygiene
Software cannot clean a comb, but it removes the pressure that causes shortcuts. With Invoay salon software you can add buffer time to services so cleaning time is built into the calendar, use online booking to spread clients through the day, send WhatsApp reminders that cut late arrivals and rush, collect feedback after every visit, and track stock of gloves, disinfectant, couch roll and disposables so you never run out.
Frequently asked questions
What is the difference between sanitising, disinfecting and sterilising?
Sanitising reduces the germs left on a surface after cleaning. Disinfecting kills most harmful germs on surfaces and tools but not bacterial spores. Sterilising destroys all forms of microbial life, including spores. All three work only after the item has been cleaned.
Which salon tools must be sterilised?
Metal implements that can cut the skin or come into contact with blood, such as cuticle nippers, pushers, metal nail files, tweezers and comedone extractors, should be cleaned and then sterilised, usually in an autoclave. Blades, razors and lancets should be single-use.
Is a UV steriliser enough to disinfect salon tools?
No. UV light only reaches surfaces it shines on directly and does not remove dirt. Tools must be cleaned and disinfected or sterilised first. A UV cabinet can be used only to store tools that are already clean and disinfected.
How often should a salon disinfect tools and surfaces?
Clean and disinfect reusable tools, chairs, basins, beds and stations between every client. Clean high-touch areas such as the reception desk and door handles several times a day, deep clean foot spas and floors daily, and do a deeper clean of the whole salon weekly.
Can emery boards and buffers be reused?
No. Emery boards, buffers, pumice stones, orange sticks, sponges and wax spatulas are porous and cannot be properly disinfected, so they should be used on one client and then given to the client or thrown away.
What temperature does an autoclave use?
CDC guidance gives minimum exposure times for wrapped items of 30 minutes at 121 degrees Celsius in a gravity-displacement steam steriliser and 4 minutes at 132 degrees Celsius in a pre-vacuum steriliser. Always follow your machine’s manual for the exact cycle.
How long should salon staff wash their hands?
The WHO handwashing technique with soap and water takes 40 to 60 seconds. An alcohol-based hand rub takes 20 to 30 seconds and can be used between clients when hands are not visibly dirty.
