The most important rule
Marble, limestone, travertine, Jura marble and cement tiles contain lime and tolerate no acid – not even vinegar or citric acid. Only use acidic products such as cement haze removers or descalers on acid-resistant surfaces (granite, porcelain stoneware, ceramics). For lime-based stone there are acid-free products such as UR 27. If in doubt, always test on an inconspicuous area or contact StoneClear.
