Copper Oxide - Marble

Copper oxide stains, often recognisable by their green or blue tint, can be challenging to remove from marble due to the stone’s calcite composition and smooth surface. These stains typically arise from aging copper fixtures—such as pipes, gutters, or decorative elements—that leach copper oxide onto nearby marble surfaces. PureSeal’s copper oxide removers are specifically formulated for marble, dissolving these stains effectively without risking etching or dulling the stone’s finish.

Marble requires a gentle yet powerful approach, and our copper oxide removers are crafted to safely lift even the most persistent stains while preserving the stone’s natural appearance. For best results, follow application instructions carefully, perform a test patch to ensure compatibility, and use the appropriate PPE.
