A system and process for recycling alkaline aqueous cleaners for electronic components. Such cleaners generally contain saponifiers which react with rosin flux on the electronic components to form rosin soaps. Spent cleaner is concentrated, the pH is lowered to cause a separation between the cleaner and the soils within the cleaner. The cleaner then is filtered to further remove any soils. The filtered cleaner is then reconstituted to a determined concentration and pH level and returned to the cleaning system. 3201P/1-14
