All implements must be thoroughly cleaned of all visible matter or residue before soaking in disinfectant solution because ______________________________________________.
Correct Answer:
Residue will interfere with the disinfectant and prevent them from being effective.
Explanation:
Cleaning removes visible matter so the disinfectant can contact all surfaces. If there’s residue or organic debris, it can shield microbes and even react with or neutralize the disinfectant, making it less effective. By pre-cleaning, you ensure the surface is clean and the disinfectant can work properly to kill or inactivate pathogens. The other options don’t explain why cleanliness before soaking matters as clearly; labels matter, but the key reason is that residue reduces disinfectant efficacy.
