When evaluating products for cleaning noncritical items, which aspects should be considered?

• A. Dilution ratio and contact time
• B. Kill claims, contact time, and the type of solution
• C. Bloodborne pathogen kill claims and contact time
• D. Contact time and the type of solution

Answer: (B)

When evaluating products for cleaning noncritical items, the essential factors are what organisms the product is proven to kill (kill claims), how long the surface must stay wet to achieve that kill (contact time), and the form or type of the solution you’ll use (ready-to-use versus diluted, application method). Kill claims show you the product’s proven effectiveness against common pathogens you want to prevent from spreading. The specified contact time tells you how long the surface must remain wet for disinfection to occur; skipping or shortening this can leave pathogens viable. The type of solution matters for practical use—whether you can apply it directly, if it needs dilution, and how it interacts with surfaces and materials. Together, these elements ensure reliable disinfection of noncritical items. Choices that omit kill claims, or omit either contact time or the form of the solution, don’t provide the full, actionable guidance needed for safe and effective use.
