Accelerated Hydrogen Peroxide® (AHP®) is a patented synergistic blend of commonly used, safe ingredients that when combined with low levels of hydrogen peroxide dramatically increase its germicidal potency and cleaning performance. To ensure maximum efficacy, AHP concentrated products can be diluted with automated dilution control systems. However, just as we wouldn't run our automobiles without regular oil changes and tire rotations, so to we shouldn't operate these systems without regularly scheduled preventative maintenance. This evaluation focused on an AHP disinfectant and its associated dilution system to emphasize the importance of performing quality checks on other hospital grade disinfectants that are diluted and dispensed from automated control systems.
