it matters a great deal whether any wax has been put on it, in which case you need to avoid contact with water for more than a very short time - use a sponge mop that is squeezed to the point of not dripping, best of all go over the floor with a clean, dry, absorbent cloth afterwards, such as a towel. As for detergents, use something fairly mild but make sure you wash sufficiently frequently to avoid build up of dirt. Vacuum regularly to avoid grit being rubbed in and/or scratching - best of all do not wear outdoor footwear indoors (ever).
