Disinfection and sterilization in a beauty salon

As cosmetic professionals, you surely know that clean tools and a safe environment reflect your work. In this article, we will meticulously examine the differences between cleaning, disinfection, and sterilization, review a standardized step-by-step protocol, and highlight the most common mistakes you might unknowingly be making in your salon.

1. Hygiene as a professional standard

Hygiene represents the foundation of safe and professional work in a beauty salon. Regardless of whether we perform manicures, aesthetic pedicures, medical pedicures, or other cosmetic services, it is the responsibility of every professional to provide the client with the highest possible level of safety.

Proper disinfection and sterilization of instruments reduce the risk of transmitting bacteria, fungi, and viruses, and contribute to client trust and the salon's reputation. A professional salon is recognized not only by the quality of its services but also by its consistent adherence to hygiene standards.

2. Differentiating between procedures

For correct execution of hygienic procedures, we must understand the difference between cleaning, disinfection, and sterilization.

Cleaning (Mechanical vs. Ultrasonic)

Cleaning is the first and mandatory step in preparing instruments. Its purpose is to remove visible dirt, skin residues, dust, material residues, and other impurities from instruments and attachments.

Cleaning can be performed in two ways:

Mechanical cleaning

• manual brushing of instruments,
• cleaning of pedicure attachments,
• removal of skin residues, dust, and material.

Ultrasonic cleaning

• use of an ultrasonic cleaner, which removes impurities from instruments using high-frequency vibrations,
• effective removal of dust, dead skin, and material residues even from hard-to-reach places,
• especially recommended for pedicure attachments and instruments with small crevices.

It is important to emphasize that disinfection and sterilization cannot replace cleaning. If skin or material residues remain on the instrument, further procedures will not be effective.

Disinfection

Disinfection reduces the number of microorganisms to a safe level. It destroys most bacteria, fungi, and viruses, but not all microbial spores.

After mechanical or ultrasonic cleaning, instruments are immersed in instrument disinfection liquid or a concentrate for disinfecting cosmetic tools, prepared according to the manufacturer's instructions.

For disinfection, it is important to observe:

• correct mixing ratio of the concentrate,
• sufficient exposure time,
• regular change of the disinfectant solution,
• use of an appropriate instrument disinfection container.

Disinfection is an important intermediate step, but it does not guarantee instrument sterility.

Sterilization

Sterilization represents the highest level of protection. It destroys all microorganisms, including bacterial spores, making it indispensable for preparing instruments for reuse.

Before sterilization, instruments must be:

• cleaned,
• disinfected,
• completely dry,
• properly packaged in sterilization pouches.

Sterilization is performed in an autoclave or a professional sterilizer. Sterilization pouches ensure that the instrument remains sterile until the moment of use with the client.

3. Microbiological aspect

To ensure the highest level of safety, every salon must use a uniform instrument preparation protocol.

Step 1: Mechanical or ultrasonic cleaning

After use, remove all visible residues of material, skin, and dust.

Instruments can be:

• manually cleaned with a brush,
• cleaned in an ultrasonic cleaner.

For pedicure attachments, ultrasonic cleaning is especially recommended as it allows for the removal of impurities even from hard-to-reach surfaces.

Step 2: Disinfection

Immerse cleaned instruments in instrument disinfection liquid or a solution prepared from a concentrate for disinfecting cosmetic tools.

Instruments must be completely submerged for the entire exposure time of the agent.

Step 3: Rinsing and drying

After disinfection is complete, rinse the instruments according to the manufacturer's instructions and dry them completely.

Never pack wet instruments into sterilization pouches.

Step 4: Packaging

Package dry instruments in sterilization pouches for autoclaving.

If necessary, also use sterilization indicators for additional control of the sterilization process.

Step 5: Sterilization

Sterilize packaged instruments in an autoclave according to the manufacturer's prescribed program.

Step 6: Storage

Store sterile instruments in a clean, dry, and closed space until the moment of use.

5. Most common mistakes

Among the most common mistakes are:

• skipping mechanical cleaning before disinfection,
• improper preparation of disinfectant solutions,
• insufficient disinfection time,
• packaging wet instruments,
• incorrect use of sterilization pouches,
• mixing clean and unclean instruments,
• improper storage of sterile instruments,
• use of damaged sterilization pouches,
• overloading the autoclave.

Even a single mistake can reduce the effectiveness of the entire process.

6. Work organization and equipment

A well-organized workspace enables consistent implementation of hygiene procedures.

It is recommended to clearly separate:

• used instruments,
• cleaning area,
• disinfection area,
• packaging area,
• area for sterile instruments.

Basic equipment includes:

• ultrasonic cleaner,
• instrument disinfection container,
• instrument disinfection liquid,
• concentrate for disinfecting cosmetic tools,
• sterilization pouches,
• sterilization indicators,
• autoclave or sterilizer.

7. Standardization and consistency

The greatest advantage of a professional salon is consistency. Regardless of the number of clients or the salon's occupancy, procedures must be the same for every service.

Every instrument must go through the same cleaning, disinfection, and sterilization process. Only in this way can we ensure the same level of safety for every client.

Correct procedures are not a matter of individual choice, but a professional standard that every team member must adhere to.

8. Daily protocol

Before starting work

• prepare sterile instruments,
• check the stock of disinfectants,
• check the stock of sterilization pouches,
• clean work surfaces,
• check the operation of the autoclave and other equipment.

During work

• after each client, disinfect the work surface,
• use sterile instruments,
• maintain hand hygiene,
• immediately place used instruments in the designated container.

After finishing work

• clean and disinfect the workspace,
• prepare instruments for the next sterilization cycle,
• clean the ultrasonic cleaner and disinfection containers,
• check the condition of equipment and supplies,
• prepare the workstation for the next working day.

Consistent implementation of disinfection and sterilization procedures is not only a professional requirement but also an important part of responsibility towards client health, service quality, and the salon's reputation.
