Tiles and mosaic: an all-purpose concentrate works well and is the most economical choice. Marble and granite: always use a pH-neutral cleaner — acidic products (vinegar, lemon, limescale removers) dull polished stone. Grout lines: a dedicated grout cleaner with a stiff brush lifts the dark lines that a mop leaves behind.
Concentrate or ready-to-use?
Concentrates are diluted in a bucket of water, so a 5 liter can lasts a household many months and is the usual choice for offices. Always follow the dilution on the label — using more product leaves a sticky film that attracts dust.
