Before immersing implements in an EPA grade disinfectant, what must be done first?

Before immersing implements in an EPA grade disinfectant, it is essential to wash, rinse, and dry them first. This step is crucial because the effectiveness of disinfectants can be significantly compromised if the items being disinfected are not properly cleaned beforehand. Any visible debris, organic matter, or product residue can create a barrier that inhibits the disinfectant from reaching the surface of the implement and killing pathogens effectively.

Washing the implements removes dirt and contaminants, rinsing ensures that no soap or cleaning agent remains to interfere with the disinfection process, and drying prevents any moisture that could dilute the disinfectant or promote microbial growth. This thorough cleaning process aligns with standard infection control practices, ensuring a higher level of safety and hygiene in a cosmetology setting.

The other options, while related to hygiene and tool maintenance, do not serve as necessary preliminary steps before using an EPA grade disinfectant.
