In instrument reprocessing, cleaning performance depends not only on the detergent chemistry itself, but also on its compatibility with the washer-disinfector system. Excessive foam is often an overlooked factor that can compromise cleaning efficacy, reduce equipment lifespan, and potentially impact patient safety.
How Does Foam Affect Washer-Disinfectors?
🔹 Reduces the mechanical action of spray arms and water jets
🔹 Promotes cavitation in the recirculation pump
🔹 Interferes with sensor performance
🔹 Impairs the final rinse process
🔹 Negatively impacts drying efficiency
Effective Foam Control Strategies
✅ Select detergents specifically designed for washer-disinfectors, preferably low-foaming formulations..
✅ Perform routine calibration and verification of chemical dosing systems.
✅ Monitor water quality regularly, particularly water hardness, which can contribute to excessive foam formation.
✅ Maintain pumps, sensors, spray arms, and hydraulic systems according to the manufacturer's recommendations.
✅ Always follow the validated detergent concentration and operating temperature specified by the manufacturer.
In instrument reprocessing, more foam does not mean better cleaning. On the contrary, excessive foam can reduce cleaning efficiency, interfere with washer-disinfector performance, and increase the risk of chemical residues remaining on medical devices.
