The Consequences of Using Oxalic Acid to Clean Stone Rust Stains

1. Limitations of Oxalic Acid Cleaning

Oxalic acid, an acidic substance, has certain limitations when cleaning stone rust stains. It is mainly effective against alkaline contamination and is not suitable for acidic contamination such as pigments.

2. Destruction of Stone Structure

Oxalic acid reacts with the carbonate components in marble, leading to the destruction of the stone surface structure. Over time, the stone may lose its luster and become powdered.

3. Stone Dulling and Yellowing

Using oxalic acid to clean marble and other stones can easily lead to the stone surface losing its luster and even turning yellow, especially artificial stones, because the resin component accelerates aging under the action of acid.

4. Inducing Diseases

Acidic solutions penetrating into the interior of the stone can induce various diseases, such as rust yellowing. Iron elements are easily oxidized into rust under acidic conditions.

5. Precautions for Using Rust Remover

High-quality rust removers should contain not only acidic components but also appropriate additives to maintain the stability of iron ions. Simple acidic mixed liquid rust removers are likely to cause problems to recur.

5.1 Distinguish Between Marble and Granite Rust Removers

Since the chemical properties of marble and granite are different, rust removers must be distinguished when used. Granite rust removers should not be used for marble.

5.2 Treatment of Surface and Deep Rust Stains

  • Surface Rust Stains: Directly brush the rust remover on the surface, or use surface grinding methods.

  • Deep Rust Stains: Requires a certain dosage and reaction time, sometimes repeated use is necessary.

6. Care After Construction

After using rust remover, it is necessary to clean with water and protect with high-quality stone care agents to thoroughly remove residues and prevent oxidation reactions from occurring again.
