Copper Oxide - Slate

Copper oxide stains, often recognisable by their green or blue tint near copper fixtures, can be difficult to remove from slate due to the stone’s natural layering and occasional porosity. These stains typically arise from weathered copper pipes, gutters, or decorative elements that leach copper oxide onto adjacent slate surfaces. PureSeal’s copper oxide removers are specifically formulated for slate, effectively breaking down these stains without risking damage or discoloration to the stone’s natural finish.

Because slate benefits from a gentle approach, our copper oxide removers are designed to lift these challenging stains safely and thoroughly. For best results, carefully follow product instructions, conduct a test patch to confirm compatibility, and use the recommended PPE.
