Iron & Rust - Indian/Sandstone

Iron and rust stains can be particularly challenging to remove from sandstone, as the stone’s porous structure allows stains to penetrate deeply, leading to difficult-to-remove reddish-brown discoloration. These stains often originate from metal fixtures, outdoor furniture, or iron-rich water runoff. PureSeal’s iron and rust removers are specially formulated for sandstone, effectively lifting stains while preserving the stone’s natural appearance.

Using the right type of acid-based cleaner is key to protecting sandstone. Harsh acids can damage the stone’s surface, so our specialised formulas employ gentler acids that effectively break down rust and iron stains without risking damage. For best results, follow product instructions, perform a test patch, and wear suitable PPE during application.
