A solvent recovery method for removing cleaning solvent from dirty, solvent-laden filter cartridges. The cartridges are placed in a low temperature, water vapor environment. Water vapor passing through the cartridges combines with and replaces the solvent in the cartridges and is then condensed into liquid form. The liquid is deposited in a stratum-forming separator. The water is bled-off to form makeup water in the water vapor environment and the solvent is bled-off from the separator in to a receiving tank from which it may be selectively drawn.
