1.2 Levels of Decontamination: Cleaning, Disinfection & Sterilization

Three levels, one Georgia sequence

The PSI National Esthetician Theory outline names levels of decontamination as cleaning, disinfection, and sterilization. The Environmental Protection Agency (EPA) uses related public-health product classes: sanitizers reduce microorganisms to a level a public-health code treats as safe but do not necessarily eliminate them; disinfectants destroy or irreversibly inactivate infectious fungi and bacteria on nonliving surfaces but not necessarily bacterial spores; sterilants eliminate or destroy microbial life including spores. Georgia's facility rule does not ask you to pick a marketing synonym. It gives a sequence you can run on a tweezer at 4:00 p.m. on a Saturday.

Rule 240-4-.04 opens with a ban: the use of any article that is not properly cleansed and disinfected on any client is prohibited. Each facility must provide correct disinfection and storage standards at all times. Some Board cross-references still point school equipment or posting language to "Chapter 240-5." Chapter 240-5 is the apprentice chapter. The operative cleansing, disinfection, and storage procedures for implements and equipment are Rules 240-4-.04 and 240-4-.05. Study those texts.

Cleaning: warm soapy water is not optional pre-work

Cleaning is the removal of visible soil, product, hair, sebum, and debris. Rule 240-4-.04 says that after each use, multi-use tools must be cleaned with warm soapy water to remove all hair and debris, and then disinfected by complete immersion. If wax, makeup, or dried blood is still on an extractor, the disinfectant cannot contact the metal. You have not "saved time." You have soaked a dirty tool in a jar that must, by the same rule, stay free of debris and contaminants at all times.

Cleaning is also the first step for machines and the daily workstation. Wipe what you can see: facial-bed vinyl, steamer housing, magnifying-lamp arms, wax-pot exterior, trolley handles. Use a detergent or the cleaner's product the Safety Data Sheet (SDS) and the EPA label allow on that surface. Then apply an EPA-registered disinfectant as the label directs for surfaces that cannot be immersed. Georgia's 10-minute complete immersion clock is written for implements that go into a disinfectant container. A facial bed is not immersed; it is cleaned and then disinfected as a workstation. Do not drag a dripping immersion basket across the pillow you just "disinfected."

Disinfection: Georgia's 10-minute complete immersion

Disinfection is chemical destruction of many or all pathogenic microorganisms on an inanimate object, except bacterial spores unless the product and process claim that higher kill. Georgia's implement rule is specific:

1. Clean with warm soapy water.
2. Place the item in a disinfectant container large enough for complete immersion (enough solution to cover all surfaces of the item).
3. Hold 10 minutes in a disinfectant whose label indicates it has been registered with the EPA as a disinfectant.
4. Rinse thoroughly with clean warm water and blot dry.
5. Store under Rule 240-4-.05. Tools cannot be stored in disinfectant.

The solution must remain free of debris and contaminants and must be changed daily. "Daily" is not "when it looks cloudy if you remember." If a film of makeup or wax floats on the jar at 2:00 p.m., the jar is already out of compliance with the debris-free sentence — change it, do not top it off.

Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) labeling still applies: it is a violation of federal law to use an EPA-registered pesticide, including a disinfectant, in a manner inconsistent with its labeling. If the EPA label requires a contact time longer than 10 minutes, you cannot cut that time because Georgia also says 10 minutes. Meet both: Georgia's complete-immersion 10-minute floor and the label. If the label's immersion time is shorter than 10 minutes, Georgia still requires 10 minutes of complete immersion for these implements.

Pedicure equipment in the same rule uses different clocks because a basin is not a tweezer. After each client, pedicure units that hold water are cleaned of visible debris and then disinfected for at least fifteen (15) minutes with an EPA-registered disinfectant. End-of-day circulation is 10 minutes, then a 10-minute hot-water flush. Weekly bleach circulation uses one teaspoon of 5.25% EPA-registered bleach per gallon for 5 to 10 minutes. A log book of dates and times must stay in the pedicure area. Many pure esthetics suites never install a whirlpool. If you work in a mixed Georgia facility, those clocks still exist. Do not apply the 15-minute basin rule to a pair of tweezers, and do not apply the 10-minute tweezer rule to a whirlpool jet system.

Towels and linens contaminated with blood or bodily fluids must be washed separately with an EPA-registered disinfectant along with laundry detergent per the manufacturer's instructions with each load. Sinks must be thoroughly cleansed and disinfected with an EPA-registered disinfectant and kept free of hair and debris.

Sterilization: the autoclave Georgia actually accepts

Sterilization destroys all forms of microbial life on an object, including bacterial spores. Rule 240-4-.04(2)(c) states that an autoclave that meets or exceeds ANSI/AAMI ST55:2010 or ISO 17665 standards for producing high-temperature steam (121°C to 134°C) is an acceptable method of sanitizing implements. The Board's sentence uses the word sanitizing. The PSI outline's third level is sterilization. On the exam and on the job, treat a qualifying autoclave as the heat-steam option Georgia accepts instead of (or in addition to) chemical immersion — not as a magic box that skips cleaning. Load a soiled extractor into an autoclave and you bake soil onto steel.

Rule 240-4-.04(2)(d) is the matching negative: ultraviolet lights, dishwashers, and steam devices are not acceptable methods of cleansing and disinfection. That sentence ends three salon myths:

• A UV "sterilizer" cabinet does not disinfect. Rule 240-4-.05 allows a UV cabinet for storage only after proper cleansing and disinfection, and the cabinet must be labeled "Clean Implements."
• A kitchen dishwasher, even on sanitize cycle, is not an acceptable method.
• A facial steamer, towel steamer, or other steam device is not disinfection. The steamer treats skin. It does not replace the immersion jar.

Georgia does not publish a required number of autoclave spore tests per week in Rule 240-4. If a manufacturer or ANSI/AAMI document specifies monitoring, follow that device's instructions. Do not invent a Board-published test frequency that the rule text does not contain.

Multi-use tools you actually pick up: extractors, tweezers, brushes

Rule 240-4-.04 lists multi-use tools constructed of nonporous materials such as metal, glass, or plastic. The esthetics-relevant lines include tweezers, comedone extractors (the Board text types this as "come done extractors"), brushes, nylon-bristle dusting brushes that can be disinfected, reusable gloves, reusable pencil sharpeners, and any other metal or non-porous tools. Student kits under Rule 240-16-.01 include tweezers and comedone extractors — those two are the daily multi-use pair in a Georgia facial room.

Reusable gloves on that multi-use list must be cleaned and disinfected like other multi-use items if the salon actually reuses them. Disposable gloves appear on the single-use list and are discarded after one use. Do not "wash" a disposable glove and call it disinfection.

Machines, wax pots, and the daily workstation

The PSI outline splits cleaning and disinfection into contaminated tools, machines and equipment, and the daily workstation. Map that onto Georgia equipment you already own:

Level 2 curriculum even budgets 1 service-application hour / 2 applications for facial stations, beds, and equipment and 1 hour / 2 applications for hair-removal and waxing stations, plus 3 hours / 6 applications for implements. Those hours exist because a pretty room can still be a dirty room.

Storage is part of decontamination

Disinfection fails if the dry tweezer goes into a drawer with yesterday's dirty loop. Rule 240-4-.05:

• Disinfected tools: clean, closed, airtight drawer or container labeled "Clean Implements."
• Soiled tools: separate, closed, covered container labeled "Dirty Implements," never stored with clean implements, never used again until processed under 240-4-.04.
• Blood-contaminated disposables: hazardous-waste container with a biohazard label and/or the words "Contaminated Implements."
• Clean towels: closed cabinet, container, or closet (restroom hand towels are the listed exception).
• Used towels: closed container until laundered.
• Bloody towels: separate closed container with a biohazard label and/or "contaminated linen."

Realistic Georgia scenarios

Scenario A — the overnight soak. Closing tech leaves extractors in the disinfectant because "they will be extra clean in the morning." Rule 240-4-.04 says tools cannot be stored in disinfectant. Morning rust and a noncompliant jar are the result. Dry them and store in Clean Implements.

Scenario B — UV as the whole process. A spa advertises "UV sterilized tweezers." If the tweezers only sat under a lamp, Georgia does not accept that as cleansing or disinfection. UV storage is legal after soap-and-water cleaning and 10-minute EPA immersion (or a qualifying autoclave), with the cabinet labeled Clean Implements.

Scenario C — dishwasher. A suite owner runs metal tools through a countertop dishwasher. Rule 240-4-.04(2)(d) rejects dishwashers as a cleansing and disinfection method.

Scenario D — dirty and clean in one bowl. A rolling cart has one open bowl of mixed damp tools. There is no airtight Clean Implements container and no Dirty Implements container. That cart fails 240-4-.05 before an inspector opens a cabinet.

Traps

• Skipping warm soapy water because the disinfectant "is strong enough"
• Counting a facial steamer, towel cabbie, or UV light as disinfection
• Storing implements in the disinfectant jar overnight
• Changing disinfectant "when it looks dirty" instead of daily and whenever debris appears
• Using the 15-minute pedicure-basin contact time as if it were the tweezer rule, or the reverse
• Labeling a drawer "sterile" when the process used was chemical disinfection, not a qualifying autoclave
• Putting clean and dirty tools in the same airtight box because the lid is fancy
