What must surfaces be treated with before applying disinfectant?

Surfaces must be treated with a cleaning agent or soap and water before applying disinfectant because this step ensures that any dirt, organic matter, or contaminants are removed from the surfaces. Disinfectants are designed to kill pathogens, but they are most effective when applied to clean surfaces. If surfaces are not cleaned first, the presence of dirt and debris can inhibit the disinfectant's ability to work properly, potentially leaving pathogens behind. This is especially critical in a nail salon setting where the risk of infection can be higher. Using soap and water breaks down and removes these contaminants, allowing the disinfectant to perform its intended function effectively.
