One ready-to-use application of Lithofin Rust-EX eliminates the oxidation before it sets permanently.\u003c\/p\u003e\n\u003ch2\u003eWhat Rust-EX Does\u003c\/h2\u003e\n\u003cp\u003eRust-EX is an acidic cleaner for natural stone, ceramic, and porcelain. At pH 1.5 it converts insoluble ferric oxide into water-soluble ferrous salts. A built-in indicator turns the liquid violet within 2 minutes, confirming the reaction. Wetting agents carry the solution 2-3 mm into porous stone, so the rust lifts out without heavy scrubbing.\u003c\/p\u003e\n\u003ch2\u003eWhen to Use\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePolished marble vanity with a metal perfume-tray ring - apply undiluted.\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/en-ie\/pages\/stone-granite\"\u003eGranite\u003c\/a\u003e patio showing iron spots from lawn furniture - apply undiluted.\u003c\/li\u003e\n\u003cli\u003eBathroom \u003ca href=\"\/en-ie\/pages\/stone-porcelain\"\u003eporcelain\u003c\/a\u003e tiles stained by iron-bearing well water - apply undiluted.\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/en-ie\/pages\/stone-sandstone\"\u003eSandstone\u003c\/a\u003e facade with old steel anchor marks - pre-wet, then apply undiluted.\u003c\/li\u003e\n\u003cli\u003eAny surface listed on \u003ca href=\"\/en-ie\/pages\/problem-rust-stains\"\u003erust-stain\u003c\/a\u003e guide - spot treat undiluted.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eHow to Apply\u003c\/h2\u003e\n\u003col\u003e\n\u003cli\u003eMask adjacent acid-sensitive areas and pre-wet very porous stone.
