How long should implements remain in disinfectant solution?

How long should implements remain in disinfectant solution?

• A. For the manufacturer's recommended contact time
• B. 60 minutes
• C. Until they look clean
• D. Overnight

Answer: (C)

Disinfection relies on a specific contact time for the product to work. The manufacturer’s label tells you exactly how long items must stay submerged or in contact with the solution for the kill claims to be valid. Simply waiting until things look clean is not reliable, because microbes aren’t visible and may still be present even on surfaces that appear spotless. So, the correct practice is to keep implements in the disinfectant for the manufacturer-recommended duration, ensuring full immersion and proper solution maintenance (within shelf life and without contamination). Pre-cleaning first helps the disinfectant reach microbes more effectively, and never rely on visual cleanliness as a disinfecting indicator.
