A solution for dysfunctional dilution: real-time detection of malfunctioning automated disinfectant dispensers using colorimetric or hydrophobic wipes that indicate disinfectant concentrations.

Automated dispensers that dilute concentrated disinfectants with water are commonly used but can malfunction. We provide proof-of-principle that incorporating indicators into wipe products could be an effective method to provide environmental services staff with real-time visual indication that disinfectants are present and at correct concentrations with every use.
