In the title salt, C6H10N22+·C10H6O6S22−·CH3OH·3H2O, the cation lies on a mirror plane and the anion on a center of inversion. One lattice water molecule is located on a mirror plane, another is equally disordered over two sites. The methanol solvent molecule is disordered about a mirror plane. In the crystal, the cations, anions, water and methanol molecules are linked by O—H⋯O and N—H⋯O hydrogen bonds, forming a three-dimensional network.
