Akemi Marble Rust Remover 500 mL — Acid-Free Rust Stain Remover for Marble & Limestone

Akemi Rust Remover Marble is an aqueous, slightly alkaline, ready-to-use cleaner that lifts superficial rust stains from acid-sensitive stone. Because it contains no acids, it is safe on polished marble and limestone where conventional acidic rust removers would etch. It converts the rust so it can be rinsed away with clear water.

  • Acid-free — safe on polished marble and limestone that acidic removers would etch.
  • Removes superficial rust stains left by fertilizers, tools and iron objects.
  • Ready-to-use; converted rust rinses off with clear water.
  • Ideal for surfaces already laid or ready to be laid.
  • A temporary violet tint may appear and clears on its own within about 1–2 days.

Apply undiluted and saturated to the dry surface, let it act 5–10 minutes (never longer, to avoid stain formation), assist with a brush if needed, then rinse thoroughly with clear water. Best on polished marble or limestone. Afterward, protect the stone with an Akemi impregnation or stain repellent to help prevent new rust. Always test an inconspicuous area first.

Wear appropriate PPE. Follow manufacturer instructions and safety regulations.
