Sanagloss is where Toto bakes an extra layer into the bowl and throughtout the plumbing of the toilet to make the porcelain a truly smooth surface. Porcelain is porous on a microscopic level. This gives bacteria and mildew places to settle in and grow, hence the reason you see red and black mildew stains in the bowl. Sanagloss helps prevent that by filling all those small holes. It also helps residue not stick to the inside of the bowl as much. This doesn't mean you don't have to clean your bowl, but it does keep the maintenance level down.
