{"product_id":"rost-ex-rostentferner-stein-beton","title":"Rust Remover","description":"\u003cp\u003eRost-Ex is a rust remover for stone and concrete that extracts rust stains from all types of stone such as concrete, granite, slate, marble, and shell limestone. Typical damage patterns include stains from vases, parasol stands, or metal furniture on patios and grave sites. Rust originating from inside the stone can also be treated. The practical difference from classic rust removers lies in the combination of active principle and control: The product extracts rust from the pore structure, instead of merely dissolving it superficially, and indicates when the reaction is complete through a violet discoloration. This allows the operation to be controlled without prior experience, and the treatment is repeated until the rust is no longer visible. The product contains a sulfur compound and smells accordingly, which is why work should only be carried out in well-ventilated areas.\u003c\/p\u003e\u003ch3\u003eYour Advantages at a Glance\u003c\/h3\u003e\u003cul\u003e\n\n\u003cli\u003eExtracts rust from the pore structure of stone and concrete\u003c\/li\u003e\n\n\u003cli\u003eViolet discoloration indicates the progress of the reaction\u003c\/li\u003e\n\n\u003cli\u003eAlso effective on rust from inside the stone\u003c\/li\u003e\n\n\u003cli\u003eCan be used on marble, granite, slate, and shell limestone\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\u003ch3\u003eProduct Application\u003c\/h3\u003e\u003cp\u003eBefore use, test material compatibility. Apply Rost-Ex undiluted to the stains to be removed and allow it to act until the product turns violet; this discoloration serves as an indicator for the progress of the reaction. Then rinse with water and repeat the treatment until the rust is no longer visible. After the exposure time, rinse with plenty of water until the violet discoloration no longer appears. Use only in well-ventilated areas, as the product contains a sulfur compound and smells accordingly. Wear protective gloves and safety glasses, cover adjacent metal parts.\u003c\/p\u003e\u003ch3\u003eDosage\u003c\/h3\u003e\u003cp\u003eReady to use, apply undiluted and do not dilute\u003c\/p\u003e\u003ch3\u003eConsumption and Yield\u003c\/h3\u003e\u003cp\u003eSince it is only applied selectively to the rust stains, a 1-liter bottle is sufficient for numerous individual stains or approximately 3 to 5 m² of continuously treated area.
