- Yellow Rust. Iron oxide-hydroxide FeO(OH)H2O (high moisture) Yellow rust is present in metals that are found in large amounts of standing water.
- Brown Rust. Oxide Fe2O3 (high oxygen/low moisture)
- Black Rust. Iron (II)oxide – Fe3O4 (limited oxygen)
Is rust a form of mold?
You can easily tell a mold based on the area it has formed. Note that molds are likely to grow in damp and humid areas. On the other hand, rust forms on metallic surfaces that are undergoing corrosion. A mold or mildew easily grows in areas such as the basement or bathrooms.
