After each use, what is the correct sequence for cleaning and disinfecting tools?

• A. soap and water, rinse, then spray with high level disinfectant
• B. spray with disinfectant only
• C. rinse only
• D. soap and water only

Answer: (A)

Cleaning first is essential because debris and organic matter can shield microbes and reduce how well a disinfectant works. Start with soap and water to physically remove oils, hair, and tissue; rinse to remove the soap; then apply a high-level disinfectant and maintain contact for the time specified by the product label. This sequence ensures surfaces are truly clean before disinfection, which is why it’s the correct approach. Spraying disinfectant alone, rinsing only, or using soap and water without disinfection do not reliably achieve pathogen control.
