I used an acid based cleaner on my Kandala grey sandstone and it turned the sandstone to look like a Cotswold stone colour. One dose of LTP Ferrex changed it back to its correct colour. See photos. Brilliant product.
Used to remove acid related stain on kandla grey sandstone- acid reacted with iron sulphate in slab and turned several yellow/green. Applied 3:1 solution (about ½cupful for 1.5m² for around and hour on a hot day and jetwashed off. Good as new- brilliant!
