How do you clean hardwood floors?
Depends on the finish coat, but most of the time pine sol is alright to use. You can also try warm water and soap. But as the person above said check with your local hardware stores. Hope this helps.
It actually depends on the type of your hardwood floor and the finish coat. But the most basic step is to make sure you dry-mop or vacuum the floor to rid of any surface dirt. When mopping the floor, you have to go with the flow of the grain. You must not use a vacuum with a beater bar attachment because it can scratch your wood floor and we wouldn't want that to happen. You can also use disposable electrostatic cloths for quick dusting.
