These methods ensure the optimal elimination of bacteria, fungi, and viruses from pedicure tools, which is crucial for maintaining a safe and hygienic environment in professional settings.
The rationale behind the use of 90% alcohol lies in its antimicrobial properties. Alcohols, including ethyl alcohol and isopropyl alcohol, exhibit rapid bactericidal, tuberculocidal, fungicidal, and virucidal effects. However, they are not considered effective against bacterial spores, which can lead to infections. The cidal activity of alcohols decreases sharply when diluted below 50% concentration, and the optimal bactericidal concentration is between 60% and 90% solutions in water.
Despite its limitations, 90% alcohol plays a significant role in maintaining hygiene and safety in pedicure settings. It is essential to follow the specific guidelines provided by manufacturers of pedicure tools, which include recommended sterilisation methods, techniques, temperatures, and exposure times. By adhering to these guidelines and utilising the appropriate sterilisation techniques, professionals can ensure the safety and well-being of their clients while providing exceptional services with a strong emphasis on health and safety.

It may not achieve complete sterilisation
While 90% isopropyl alcohol is commonly used for disinfection purposes in pedicure settings, it may not achieve complete sterilisation. This is because it is a strong solvent that evaporates too quickly for reliable surface disinfection.
Complete sterilisation is crucial in the pedicure industry to ensure the safety and well-being of clients. By understanding the various methods of sterilisation, professionals can make informed decisions to eliminate bacteria, fungi, and viruses effectively. Alternative sterilisation methods, such as autoclaving and dry heat sterilisation, provide reliable and complete sterilisation. These methods use high pressure and steam to kill 99% of all microorganisms.
Additionally, 70% isopropyl alcohol is widely recognised as the most effective concentration for comprehensive microbial destruction. The slower evaporation rate ensures that surfaces remain wet long enough for disinfection to occur. This adequate contact time is critical for microbial kill.
Furthermore, it is important to follow the specific guidelines provided by the manufacturers of pedicure tools. These guidelines include recommended sterilisation methods, techniques, temperatures, and exposure times. By adhering to these instructions, professionals can have confidence in the sterilisation process and guarantee client safety.
While 90% alcohol is a useful tool for reducing the microbial load, it may not achieve complete sterilisation in all cases. Therefore, integrating it into a comprehensive approach to hygiene and infection control, alongside other sterilisation methods, is essential for creating a safe and hygienic environment in professional pedicure settings.

Alternative methods offer increased effectiveness
While 90% alcohol is a commonly used disinfectant for pedicure tools, alternative methods can provide more effective sterilization. These methods include:
Autoclaving
Autoclaves are medical-grade devices that use pressurized steam to thoroughly eliminate bacteria, fungi, and viruses. They offer professional-grade sterilization and are highly effective in killing microorganisms.
Boiling Water
Boiling nail tools in water for 5 to 10 minutes can help sanitize them. However, this method is only suitable for sturdy metal tools as it may damage delicate instruments.
UV Light Sterilization
UV light sterilizers are an efficient and easy-to-use alternative that effectively kills bacteria and viruses. However, it is important to ensure proper usage as UV light may not reach all areas of complex tools, and prolonged exposure can cause damage.
Barbicide
Barbicide is an excellent disinfectant for cleaning nail tools, including clippers, files, and buffers. It is a chemical disinfectant that, when used according to the manufacturer's instructions, effectively sanitizes pedicure tools.
Alcohol Soak
While 90% alcohol may dry too quickly for an effective soak, a dip or soak in 70% isopropyl alcohol solution for at least 30 minutes can be an effective method for most nail tools. Alcohol kills bacteria and viruses and is a great choice for regular sterilization.
In addition to these alternative methods, it is crucial to prioritize proper hand hygiene practices, regular cleaning and maintenance of tools, and the use of single-use disposable tools whenever possible. Adhering to manufacturer guidelines and specific sterilization instructions ensures the effectiveness of the sterilization process and the safety of clients.

70% alcohol is recommended for general disinfection
While 90% alcohol is commonly used for disinfection in pedicure settings, it is important to note that alternative sterilization methods, such as autoclaving and dry heat sterilization, offer more effective elimination of microorganisms from pedicure tools. Ensuring proper sterilization is crucial for maintaining a safe and hygienic environment for clients.
When it comes to disinfection, 70% isopropyl alcohol (IPA) is widely recognized as the optimal choice. Leading health authorities, including the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO), endorse its use. The effectiveness of 70% IPA lies in its ability to maintain adequate contact time with the surfaces being disinfected. The presence of water in the solution slows down evaporation, ensuring that the disinfectant remains in liquid form long enough to kill microorganisms.
The "more is better" logic often associated with higher concentrations of alcohol is a fallacy in the context of disinfection. While 91% and 99% IPA solutions are also available, their rapid evaporation and low water content result in insufficient contact time with the surfaces being treated. This reduced contact time diminishes their overall effectiveness as disinfectants.
The versatility of 70% IPA makes it suitable for various applications, including medical, pharmaceutical, and manufacturing operations. It is safe for use on skin antisepsis prior to medical procedures, disinfecting non-critical medical devices, and maintaining hygiene on environmental surfaces. Additionally, 70% IPA is recommended for general disinfection of surfaces like kitchen and bathroom countertops. Its effectiveness extends to common viruses such as the flu virus, the common cold, HIV, and SARS-CoV-2.
Overall, 70% isopropyl alcohol is a reliable and economical choice for comprehensive microbial destruction. Its slower evaporation, optimal germicidal action, and endorsement by leading health authorities make it the recommended option for general disinfection.

Heat sterilisation techniques provide reliable and complete sterilisation
While 90% alcohol is commonly used for disinfection in pedicure settings, alternative sterilisation methods offer increased effectiveness in eliminating microorganisms from pedicure tools. Heat sterilisation techniques, such as autoclaving and dry heat sterilisation, provide reliable and complete sterilisation.
Heat sterilisation is a well-known method for inactivating microorganisms. It is a traditional approach that dates back to the early 19th century and is widely used in the medical device industry and research laboratories. Heat treatment methods are classified into two main categories: dry heat and steam sterilisation.
Dry-heat sterilisation relies on conduction, where the exterior surface of an object absorbs heat and transfers it to the next layer until the entire system reaches equilibrium. This method is suitable for sterilising powders, glass, metals, and glass-composites. To achieve effective neutralisation and inactivation of spores, contamination, and pyrogens, temperatures between 105°C and 190°C must be maintained for at least 30 minutes in a dehydrated environment.
There are two types of dry-heat sterilisers: static-air and forced-air. Static-air sterilisers, also known as oven-type sterilisers, use heating coils at the bottom of the unit to heat the air inside the chamber through gravity convection. This type of steriliser is slower to heat and less uniform in temperature control compared to forced-air sterilisers. Forced-air sterilisers, or mechanical convection sterilisers, use a motor-driven blower to rapidly circulate heated air throughout the chamber, allowing for a more efficient transfer of energy to the instruments.
Moist heat sterilisation, also known as steam sterilisation, involves using temperatures of approximately 121–129 °C with pressure. This method is effective, easy to control, and cost-effective. However, it is limited to packages made of heat-sensitive materials or multilayer laminated packages. The sterile air used in this process is typically sterilised at temperatures ranging from 260 to 320 °C.
