Filters used in the beverage industry fouled by polyphenol-protein complexes and carbohydrate polymers can be cleaned by treating the filters either with the following methods:Solubilization of at least part of the carbohydrate polymers followed by a treatment of the resulting polyphenol protein complex with an oxidative chemical.Treatment of the fouled filters through a back-wash method using an oxidative chemical. In both cases it is not necessary to rinse the membranes after cleaning with a reductive chemical.
