WebIn terms of rust removal, these two types of acid react differently to iron (III) oxide. For instance, a strong acid in its pure form (e.g., sulphuric or hydrochloric acid) can react quickly and remove rust within hours or even minutes. However, these acids are quite caustic and eat away at the metal underneath the rust.
