Copper Oxide - Limestone/Travertine

Copper oxide stains, often seen as green or blue discolouration near copper fixtures, can be challenging to remove from limestone due to the stone’s porous and sensitive nature. These stains commonly result from weathered copper pipes, gutters, or decorative elements that leach oxide onto nearby surfaces. PureSeal’s copper oxide removers are specifically formulated for limestone, effectively breaking down these stains without causing etching or damage to the stone’s calcite structure.

Because limestone requires a gentle approach, our copper oxide removers are crafted to lift these challenging stains safely and thoroughly. For best results, follow product instructions carefully, perform a small test patch to confirm compatibility, and always use the appropriate PPE. With PureSeal’s copper oxide removal solutions, professionals can restore limestone surfaces affected by copper staining, bringing back the stone’s natural beauty without compromising its integrity.
