The best form of keeping your wood floors clean, is preventative maintenance.
By removing shoes, or at least keeping them clean, free of debris, and dry, this will help prevent scratching and scuffing. Also remember to apply felt pads to all furniture that can come into contact with the wood floors.
As far as cleaning, dry dust moping (Swiffer) can be used at any time. For high traffic areas, an occasional damp cloth or mop can be used. You can use either diluted white vinegar with warm water or Bona K. Make sure that after any damp mop procedure that you go directly over with a dry mop or towel.
