Abstract
A method for washing an impregnated porous workpiece including a step of rotating the impregnated porous workpiece after excessive impregnant has been shaken off, in such a manner that the workpiece is immersed in and comes out of a washing liquid contained in a washing tank, forcibly causing the washing liquid to go in and out of a recessed portion such as a hole bored in the workpiece to thereby dilute and wash away residual impregnant adhering to the inside of the recessed portion.
