I have discovered a beautiful quarry tile patterned floor under the carpet in the hall and want to renovater it. What is the best thing to clean it with?
Hagesan HG extra should be available in any good tiling shop. What it says on the 'tin'? - "removes cement film, lime scale and rust stains from new quarry tile, tile and slate". I don't think it would object to doing the same on old quarry tiles. Try a test area first beforore committing the lot!
