Description
Professional rust stain removal for unpolished stone and granite. Tenax Rust Remover Liquid is a water-based acid solution developed to remove rust residues and stains from unpolished marble, stone, and granite surfaces. Apply directly to the stained area, allow to act, then rinse thoroughly. After treatment, protect the surface with Tenax Proseal or Tenax Hydrex.
⚠️ Important: This is an acid and corrosive product. Do NOT use on polished marble or polished calcium-based stone — it will etch the surface. Always test on a small hidden area before full application. Avoid contact with metal, wood, and ceramics.
How to Use
- Ensure the surface is clean and dry before application.
- Apply the product at room temperature directly to the rust-stained area.
- Leave to act for at least 1–2 hours.

- Repeat application for more stubborn stains if needed.
- Once dry, protect the surface with Tenax Proseal or Tenax Hydrex.
- Close the container tightly after use.
