Wood floors should be vacuumed and dust mopped regularly to maintain them. Doing this will stop dirt from building up and potentially damaging the floor. Any wood floor can be cleaned with a quarter-cup of apple cider vinegar mixed with a gallon of warm water. Wood floors are best cleaned on your hands and knees because you should only clean a small area at a time and then dry it and move on. You should never get wood floors too wet or let them dry naturally. Finished wood floors often can be cleaned with just water. However, the finish will eventually wear off, and you'll probably have to either re-finish the floors or start waxing them. Keeping wood floors free of dirt through vacuuming and/or dust mopping is the best thing you can do to maintain the look of your floors.
