  • Rust stains are caused by the oxidation of iron. Iron can enter the bathtub through the water supply, or it can be present in the pipes or fixtures. Rust stains are typically a reddish-brown color.
  • Mineral deposits are caused by the minerals in the water. These minerals can build up on the surface of the bathtub and create a white or gray film.
