What is the best way to clean and maintain a wood floor?

A steam mop should definitely NOT be used and any use of one will void your warranty.  This is because wood floors do not like excess moisture.  Wood floors should be swept, vacuumed or dry mopped regularly.  They can be damp mopped as required, with minimal water and a neutral cleaner such as Tarkoclean.  Periodically we recommend Refresher to revive the lacquer on the surface - this is a wipe on, wipe off product that reduces the appearance of micro-scratches and restores the floor to its original sheen in worn areas. Review our Maintenance guidelines for detailed information.
