Abstract
A cleaning process is provided that is particularly advantageous for removing oil or oil-like material from porous parts such as porous internal combustion engine components such as valves. The process utilizes oil solubilizing solvents as well as alkaline soap and water solutions and mixtures of water soluble amines and water or deionized water in conjunction with alternate pressure and vacuum cycling to effect the cleaning.
