Never clean your hardwood with water. Never use products such as soaps, detergents and oil soaps to clean your floor. Only use products recommended by the manufacturer. Place area rugs or mats at doorways and in front of the kitchen sink to help catch dirt, grit and water. Never use rubber or plastic backed as it may damage the floor.
Solid cotton is highly recommend.
Never use sheet vinyl or tile floor care products on wood floors. Spike heels, cleats and work shoes can be damaging to wood floors. Even a woman of average build with spike heels on can exert 2000 psi. Humidity control is highly recommended. To reduce excessive shrinkage in the winter a humidifier is recommended while air conditioning or a dehumidifier for the summer.
