CONCRETE & STONEWORK
Why the wrong treatment won’ t work Rust stain removers – even nonacidic solutions like our own ECOPROTEC Rust Stain Remover – won’ t remove naturally-occurring rust stains. In some cases, treating iron-rich stone with the wrong product can trigger or worsen discolouration by affecting iron compounds naturally present within the stone. This can result in‘ iron break-out’ – a reaction involving the iron within the stone that causes it to oxidise and produce the characteristic orange discolouration.
To treat this type of staining, you need to use ECOPROTEC Iron Stain Away – a treatment specifically formulated for naturally-occurring iron staining.
How to apply ECOPROTEC Iron Stain Away Dampen the surface of the stone with a little water.
Dilute the cleaner 1:1 with water and spray onto the surface. Leave to work for up to five hours. The orange staining should gradually fade and disappear. Once it has disappeared, seal the stone with ECOPROTEC Ultimate Sealer to help prevent the orange staining from returning.
So, what’ s the difference between the treatments? The chemistry used in our non-acidic Rust Stain Remover helps remove orange staining caused by rusting metal objects on the surface of the stone.
The chemistry used in Iron Stain Away treats the oxidation of naturally occurring iron within the stone, removing the resulting orange discolouration rather than removing the iron itself.
So, for rust on the stone, use ECOPROTEC Rust Stain Remover and for iron in the stone, use ECOPROTEC Iron Stain Away.
