Copper Oxide

Copper oxide, which forms naturally on copper surfaces, often appears as a dark brown to black tarnish. In outdoor environments, especially where copper is exposed to moisture, this oxidation can lead to greenish-blue stains, particularly on nearby surfaces like render or stone. These blue stains are commonly seen around copper overflow pipes or fixtures and can be difficult to remove with standard cleaners. PureSeal’s copper oxide removers are specifically designed to target and eliminate these unsightly stains, restoring both the copper and the surrounding surfaces to their original condition.

Our copper oxide removal solutions not only clean tarnished copper but also effectively remove the blue and green oxide deposits that can leach onto nearby materials, such as render or stone. Whether you’re addressing discoloration from copper roofing, pipes, or decorative features, our products offer an efficient way to restore surfaces without causing damage. Always perform a test patch before applying to delicate surfaces and ensure that the correct PPE is used.
