Polystyrene particles adhered to a glass plate were removed by a laminar flow produced in a wash-ing device equipped with a turn table of a gramophone and in a Terg-O-Tometer. The separating force was estimated from the viscosity resistance of the particles in a laminar flow. Relationships between the separating force and the removal percentage of particles from substrate were elucidated and the following results were obtained.<BR>1) When the particles were removed at various rotation speed, the removal percentages were almost invariable, though the separating force increased.<BR>2) The removal percentage increased with increasing surfactant concentration, in spite of almost invariable separating forces.<BR>3) The removal percentage increased markedly with increasing washing temperature, though the separating force decreased.<BR>4) The removal percentage obtained by use of a Terg-O-Tometer was similar to that obtained by use of a laminar flow.
