TiObased scrubbing granules, and methods of making and using such TiObased scrubbing granules are described. TiO-based scrubbing granules include granulated TiOand about 0.5% to about 20% dry weight inorganic salt binder. Other TiObased scrubbing granules include unsintered granulated TiOand about 0.5% to about 20% dry weight inorganic salt binder. Inorganic salt binder include sodium aluminate. Methods of making TiObased scrubbing granules include i) combining TiOparticles with inorganic salt binder to form TiO-binder mixture comprising from about 0.5% to about 20% dry weight binder; ii) granulating the TiO-binder mixture; and drying the granulated TiO-binder mixture to form TiO-based scrubbing granules. Methods of using such TiO-based scrubbing granules include introducing TiO-based scrubbing granules to remove adherent deposits on an inner surface of a reactor or heat exchanger during processes of forming TiOparticles and finishing the formed TiOparticles into finished pigment products.
