Maintenance of a wooden floor.

As I come across a lot of timber floors, it always astounds me that the maintenace has never been explained properly. People gladly wet or steam mop their timber floors and wonder why the timber is swelling and cupping. As I say to my customers: NEVER WET MOP a timber floor, instead use a damp microfiber mop. As what Bona is offering in their maintenace range or any other brand for that matter. As I'm familliar with the Bona range of products, I realy like that they offer a maintenance coating wich the owners can apply them selfs.
