    Galvanized iron is actually steel covered in a protective layer of zinc, but it was soon discovered that this zinc layer naturally corroded due to exposure to the atmosphere and rainwater, as well as cement, runoff, etc once corrosion occurred down to the base metal, plaques and rust would form, leading to sediment build-up that would gradually clog these drains thus, the first motivation for drain cleaners came.
