Giorda Anti-Rust Violet is a specialized cleaner for the quick removal of rust stains and metallic oxides from stone materials in general, even delicate ones such as terracotta, ceramic materials, marble, agglomerates of stone and cement.

Key strengths:

- Removes stains from external ferrous contamination (e.g., rusty metal objects)
- Eliminates stains caused by iron sulfate-based lawn fertilizers
- Acts quickly and leaves no residue. In many cases, the removal process takes just a few minutes (up to 10 minutes)
- As it is not an acidic product, it can be used on delicate stone materials such as marble, polished travertine, gravel, and polished slate

Directions for use:

Ready-to-use product.

1. Apply Giorda Anti-Rust Violet with a brush, ensuring a generous layer of product is placed over the stain to be removed.
2. Scrub the surface with a sponge or blue pad.
3. Let the product act until the rust extraction reaction has taken place (the product will turn violet). The reaction time depends on the type of material.
4. Do not allow the product to dry on the surface.
5. Once the reaction is complete, it is recommended to remove the product within 10–15 minutes by rinsing with a slightly alkaline aqueous solution (e.g., Giorda Fort diluted at 10% in water).
6. Repeat the application if necessary.

Precautions:

- Giorda Anti-Rust Violet may not completely remove rust stains caused by the oxidation of naturally occurring ferrous materials within the stone. Always perform a test before use.
- Do not apply on overheated surfaces.
- Do not use on wood.
- Protect metal surfaces.

Coverage: depending on material absorption, approximately 1L for 6–10m².
