Safe on all man-made tiles, use with care on sandstone, quarry tiles, terracotta and slate. Not recommended for use on acid sensitive surfaces including marble, limestone, granite and other natural stone. Although unlikely to mark non-ferrous metals (e.g. Aluminium), always pre-test before use.
It can be used anywhere where there are dirty tiles. It is good in restoration applications and washrooms, showers and pool surrounds, grout smear removal and builders cleans.
