Before you buy, think about the surface. A pH-neutral floor cleaner is the usual safe choice for sealed tile and stone. Strong acidic or bleach-based cleaners can dull stone and attack grout over time, so they are best kept off a floor you want to protect. Bona makes its Stone, Tile and Laminate Cleaner for these hard surfaces.

• Sealed tile and stone suit a pH-neutral hard-surface floor cleaner, used with a well-wrung mop.
• Grout and textured tile like a soft brush now and then to lift the grit a mop leaves behind.
