Phosphoric Acid


Phosphoric acid is widely used as a rust remover. When the solution in liquid or gel form is placed directly on rusted areas of steel, steel tools or steel surfaces, the rust is converted from the red oxide to a black ferric phosphate.

This is common when pickling steel. After the rust has been converted to black ferric phosphate it can easily be scrubbed off.

Phosphoric acid is also used by hobby welders as a flux to aid in soldering.
