A method and apparatus for coolant recovery system is shown. A holding tank is positioned above a cleaning tank. The holding tank receives contaminated coolant from a pre-existing machine coolant tank, and the cleaning tank holds a quantity of relatively clean coolant. Contaminated coolant is pumped into the holding tank and allowed to settle, creating a thin layer of contaminants on top of the coolant. Clean coolant is pumped from the cleaning tank into the holding tank, causing the thin layer of contaminants to drain out of the holding tank via a skim line into a processing zone in the cleaning tank. The processing zone is designed to allow only the coolant portion of the skimmed liquid to pass to the remainder of the cleaning tank. The processed coolant remaining in the holding tank is then pumped back to the machine coolant tank.
