What is the first step to properly disinfect an implement?

• A. Sterilized
• B. Thoroughly cleaned
• C. Rinsed
• D. Dried

Answer: (B)

The first step is to thoroughly clean the implement. Cleaning removes visible dirt, oils, and organic matter that can shield microorganisms and can also inactivate some disinfectants. Disinfectants work best on a surface that’s free of debris, so cleaning sets the stage for effective disinfection. After cleaning, you would rinse off any soap, dry the item, and then apply an EPA-registered disinfectant according to the label directions. This sequence—clean first, then disinfect—ensures the disinfectant can contact microbes properly and do its job.
