The correct first step before disinfecting patient care equipment is cleaning with detergent. This step is crucial because disinfectants are less effective when applied to soiled surfaces. Cleaning removes dirt, organic matter, and contaminants that could inhibit the action of the disinfectant. By using detergent to thoroughly clean the equipment first, you ensure that the subsequent disinfection process can effectively eliminate any remaining pathogens.

It's important to recognize that soaking in alcohol or rinsing with water would not adequately prepare the surfaces for disinfection because they either still leave organic material or do not remove it effectively. Wiping with a disinfectant cloth is also not appropriate as the first step, because without prior cleaning, the disinfectant may be rendered ineffective by the presence of contaminants. Properly following the cleaning step sets the stage for successful disinfection and ultimately contributes to patient safety.
