What ratio is used for heavily soiled areas?

• A. 1:4
• B. 1:1
• C. 3:1
• D. 2:1

Answer: (B)

Heavily soiled areas require a stronger cleaning mix because more soil and contaminants shield microbes from disinfectants. Using an equal parts mixture (heavy concentration) provides enough chemical strength to cut through the soil and allow the disinfectant to work effectively across the surface. A lighter mix (more water, less chemical) wouldn’t remove the heavy soil as reliably, leaving residues and potential microbes behind. While a more concentrated blend might seem even stronger, it isn’t necessary for this scenario and can increase risks to surfaces and exposure for personnel if not allowed by the product guidelines. So, using an equal parts mixture achieves the needed strength to decontaminate heavily soiled areas safely and effectively within typical protocol limits.
