A solution of bleach and water used to clean a unit should be diluted to which ratio?

• A. 1 to 10
• B. 1 to 100
• C. 1 to 50
• D. 1 to 20

Answer: (A)

Bleach works as a disinfectant only when it’s diluted to a practical strength for cleaning. The commonly recommended dilution for routine unit cleaning provides enough disinfecting power to inactivate many germs on hard surfaces while keeping the solution safer to handle and less harsh on surfaces and occupants. If the mix is weaker, it may not reliably inactivate germs; if it’s stronger, it isn’t usually necessary for daily cleaning and can increase fumes, residue, and potential surface damage. Always follow the product label for the exact concentration and dwell time, and prepare fresh solutions as directed.
