FIELD: cleaning of hydrocarbon liquids. SUBSTANCE: method comprises steps of degreasing a porous base of filters, heating it up to 100-120 C, applying (by spraying) a suspension at a pressure of compressed air in inlet of a sprayer being 0.5-3 kgf/square centimeter; spacing the porous base by a distance (10-50) cm from the inlet of a nozzle of the sprayer and moving it normally to a torch of a spraying matter with a rate 1-20 cm/s. EFFECT: enhanced filtering properties of water-repellent partition due to lowered hydraulic losses at filtration process, increased service life of the partition. 1 cl, 4 tbl
