CONSTITUTION: A stirring machine 5 stirs a liquid and particles contained in a case 3, brings the liquid and the particles into contact with tableware 1 supported or contained in a tableware shelf 2, and eliminates contamination adhering to the tableware. The stirring machine can eliminate comparatively large contamination adhering to tableware. A vibrator 6 vibrates the liquid and the particles contained in the case 3, and vibrates the liquid and the particles which come into contact with the tableware supported or contained in the tableware shelf. The vibrator 6 can eliminate comparatively small contamination adhering to the tableware. A heater 9 heats the liquid so that the contamination adhering to the tableware can be eliminated easily from the tableware.
