Lithofin Rust-ex Cleaner is a clear, nearly colourless liquid that removes rust stains and residues of metal oxide from all natural stone, porcelain and ceramic surfaces. Being mildly alkaline, it is safe to use on limestone. Applied for no more than ten minutes, it produces a visible reaction by turning purple, and works by turning rust into water soluble particles which can then be rinsed off using water and a dash of Lithofin MN Power-Clean. This patio cleaner doesn’t change the appearance of the surface, so it can be used on individual stains. One litre covers approximately 10m2.
