Iron & Rust - Slate

Iron and rust stains can be particularly challenging on slate, often resulting from metal fixtures, outdoor furniture, or iron-rich water runoff. These stains may leave noticeable reddish-brown discolouration, which can be difficult to remove due to slate’s unique composition. PureSeal’s iron and rust removers are specially formulated for slate, delivering effective stain removal while preserving the stone’s natural appearance and structure.

Choosing the correct cleaner is essential, as harsh acids can react with any iron content within the slate, potentially leading to further discoloration or surface damage. Our specialised formulas use gentler acids that effectively target rust and iron stains without risking harm to the stone’s finish. For best results, carefully follow product instructions, perform a test patch to ensure compatibility, and always use the recommended PPE.
