Mop floors with warm, not hot, water and wring out the mop to avoid using too much liquid. Don’t use steam mops as they can damage the protective coating on floorboards, letting water penetrate and damage.
To make the natural darkening of timber floors less obvious, use curtains or blinds in sunny rooms and try to move rugs around to avoid big differences on the fringe of the room.
Protect timber surfaces from water or heat damage by using heat mats when serving at the table and boards or trays under vases or potted plants.
The edges of timber veneer furniture are the weakest part of the material and can be damaged if hit “edge on”. Fully close doors and drawers and protect corners from littlies.
