Abstract: Disclosed is a means for removing fine foreign particles adhering to a fine pattern or the like without damaging the pattern or the like. After placing an object such as a photomask on a rotatable object-holding means, a highly viscous liquid is dropped on the upper surface of the object to be cleaned using a liquid supplying means. Then the highly viscous liquid is moved over the surface by rotating the object. The highly viscous liquid takes in foreign particles adhering to the object while moving over the object, thereby separating the foreign particles from the object. The foreign particles taken in the liquid are prevented from adhering the object again through zeta-potential control of the highly viscous liquid, and removed from the object.
