Remove Rust & Iron Stains from Granite, Marble, Travertine & Natural Stone Lustro Italiano Rust Remover Powder is a chelate-blend poultice powder formulated to draw rust and iron stains out of natural stone surfaces. Mix with water to a paste, apply over the stain, cover, and allow 24–48 hours for the poultice to dry and pull the rust out of the stone. Works on granite, marble, travertine, limestone, terrazzo, concrete, brick, and sanded grout. 8 oz powder. Important note for marble and calcium-based stones: Rust removal on marble will dull the treated area — this is a normal side effect of the chelate chemistry, not a new stain. After rust removal, use Lustro Italiano Etch & Water Mark Remover Powder to restore the polish, then reseal with Lustro Italiano Stone Sealer. Key Features & Benefits Chelate Blend Draws Rust Out of Stone The unique chelate formula chemically binds to iron and rust compounds and draws them out of the stone's pores through the poultice drying process — the right approach for rust stains that have penetrated below the surface. Works on a Wide Range of Stone & Masonry Effective on granite, marble, travertine, limestone, terrazzo, concrete, brick, and sanded grout — covers the full range of natural stone and masonry surfaces where rust staining occurs. Poultice Application — No Equipment Required Mix, apply, cover, wait 24–48 hours, remove. No professional equipment, no special tools required for treatment.

Use Lustro Italiano Etch & Water Mark Remover Powder to restore the polish, then reseal with Lustro Italiano Stone Sealer. Frequently Asked Questions Why does the stone look dull after rust removal? The chelate chemistry that draws rust out of the stone also removes the surface polish in the treated area — this is a normal side effect, not a new stain. On marble and other calcium-based stones, use Lustro Italiano Etch & Water Mark Remover Powder to restore the polish after treatment. What causes rust stains on stone? Rust stains on stone are typically caused by iron-containing objects left on the surface (metal cans, tools, hardware, plant pots with metal bases) or by iron minerals naturally present in the stone oxidizing over time. Water accelerates both processes. How many applications will I need? Most rust stains respond to a single application. Deep or long-standing stains may require 2–3 applications. Allow the stone to dry fully between applications. Do I need to reseal after treatment? Yes — the treatment process affects the sealer in the treated area. Reseal with Lustro Italiano Stone Sealer after treatment and polish restoration. Can I use it on granite? Yes. On granite, rust removal does not cause the same dulling effect as on marble — granite is not calcium-based and does not react the same way to the chelate chemistry. What's the difference between this and the Stain Remover Poultice Powder? The Stain Remover Poultice Powder targets organic stains (oil, grease, wine, coffee). This Rust Remover Powder uses a chelate blend specifically formulated for rust and iron stains. Use the right product for the stain type.
