The highest level of decontamination used for implements in salons is sterilization. This process is defined as the complete destruction of all forms of microbial life, including bacteria, viruses, fungi, and spores. Sterilization is vital in a salon setting, especially for tools that can penetrate the skin, such as nail clippers and drill bits, as it ensures that any potentially harmful microorganisms are eliminated.

Other methods of decontamination, like EPA disinfections, formaldehyde treatments, and sanitizing, significantly reduce the number of microorganisms but do not achieve the complete eradication that sterilization provides. EPA disinfections are effective for non-porous surfaces and can kill many pathogens, but they don't guarantee the complete removal of all microorganisms. Sanitizing only reduces the number of pathogens to safe levels on surfaces, and formaldehyde, while it can be used for disinfection, is not widely used in modern salons due to its toxicity and potential health risks. Thus, sterilization stands out as the most thorough and safe option for maintaining health and safety standards in the salon environment.
