This article describes a method of cleaning drilled holes in workpieces for removing drilling residues by means of a suspension that is made to vibrate. Small particles are dispersed in the suspension, and when this particle suspension is vibrated, the drilled holes are reliably cleaned of any material residues. In addition, the surface of the drilled hole is cleaned, for example, of oxidation residues and smoothed, the surface roughness being a function of the particle material, its hardness, size and shape.
