The right product for every surface, room by room — for the housekeeping team. If in doubt, use plain water + a microfibre cloth and ask first. Always test a new product on a hidden spot.
Two finishes do the real damage if treated wrong: the oiled wood floors (water soaks straight in) and the natural stone / marble (acid & everyday sprays etch it permanently). Get those two right and everything else is ordinary. Everything indoor is a modern rebuild — no fragile period plaster to worry about.
