A method of reproduction of a filter demineralizer for a cleanup of a condensate backwashes the filter demineralizer to separate ion-exchange resin therefrom. Backwash used for backwashing, and including the ion-exchange resin, is recirculated in a course including a crud removal apparatus to remove the crud thereby providing reproduced ion-exchange resin. On the filter demineralizer from which the ion-exchange resin has been removed, New ion-exchange resin is precoated to form a new ion-exchange resin layer, and then the reproduced ion-exchange resin is deposited on the new ion-exchange resin layer by passing the backwash through the new ion-exchange resin layer.
