Abstract
A method is set forth of removing a liquid (3) from a surface (2) of a substrate (1), which is placed in a centrifuge (4) and is then subjected therein to a rotary movement, the substrate being rotated at such a speed that the liquid is centrifuged from the surface. According to the invention, the substrate is brought into contact in the centrifuge with a vapour of a material which is miscible with the liquid and which, when mixed therewith, yields a mixture having a surface tension which is lower than that of the liquid. Due to this step, the quantity of material remaining on the surface is strongly reduced.
