ABSTRACT The invention relates to a method of controlling productivi- ty disturbing microbiological deposits, e.g. slime, on paper mak- ing equipment, which method is characterized by applying to any locus or surface of said equipment a deposition-controlling amount, preferably at least about 0.1 parts per million of dilu- tion water, of a cationic polymer or a cationic surfactant or a mixture thereof. Said application is preferably performed by spraying an aqueous solution of said polymer or surfactant directly onto the equipment to be cleaned. The invention also relates to the improved paper prepared by such a method.
