The invention concerns a method and a machine for cleaning objects in plate form such as screen printing stencils. The method consists in: immersing an object (2) to be cleaned in a cleansing composition bath consisting of an azeotropic liquid solution having a density not less than the density of residues of average density likely to soil the object (2), and adapted to loosen the residues from the object (2) without solubilising them. The object (2) is placed in a vessel with vertical walls at a distance less than 10 cm from the vertical faces of the object (2). The treating vessel (1) spills over into an overflow vessel (8). The cleansing composition is continuously removed from both vessels (1, 8), filtered and re-introduced in the treating vessel (1) top part.
