What preliminary step should you perform on tools before placing them in a disinfectant solution?

• A. Clean tools with soap and water to remove debris
• B. Rinse tools with plain water
• C. Wipe tools with dry cloth
• D. Soak tools in alcohol

Answer: (A)

Before disinfection, you must clean the tools with soap and water to remove debris. Scrubbing with soap and water lifts dirt, hair, oils, and other organic matter from every surface, which allows the disinfectant to contact microbes effectively. If debris remains, it can shield germs and reduce the disinfectant’s ability to kill them. Soaps-and-water cleaning is the essential first step that prepares instruments for the disinfectant bath. Simply rinsing with plain water leaves residues, wiping with a dry cloth doesn’t remove contaminants, and soaking in alcohol doesn’t clean off organic matter and isn’t the appropriate preparatory step before standard disinfection.
