Using an EPA-registered disinfectant according to the manufacturer’s instructions is the correct approach to disinfecting tools and implements after use. This method ensures that the disinfectant is effective against a broad range of pathogens, including bacteria and viruses, which may be present on tools that come into contact with skin or hair. The EPA (Environmental Protection Agency) registers disinfectants that meet specific safety and efficacy standards, ensuring that they are appropriate for use in professional environments such as salons and spas.

Following the manufacturer's instructions is also crucial because disinfectants vary in concentration, required contact time, and the surfaces they are suitable for. Proper application as per these instructions maximizes the disinfectant's effectiveness, providing assurance that tools are safe for use on clients.

Other methods mentioned, such as soaking in warm water or rinsing under running water, do not effectively eliminate pathogens and could lead to the spread of infections. Wiping with a dry cloth could merely transfer germs from the surface of the tool onto the cloth rather than disinfecting the tool itself. Thus, using EPA-registered solutions is essential for maintaining health and safety standards in cosmetology practices.
