Evaluating Rinsing Effectiveness in Spray-In-Air Cleaners

This study was designed to investigate the efficiency of the rinse cycle using both a spray-in-air batch and inline cleaner.

Glass slides of various surface area were affixed to the test vehicle surface at various standoff heights to emulate low standoff components. Rinse efficiency was evaluated through visual inspection, ionic contamination and localized extraction for ion chromatography. Key variables were plotted and analyzed using Minitab® software.
