I have oak floors that are over 80 years old. I mop weekly with **** 'n Span diluted in water and have no problems. Floors have a "satiny" looking finish. I have 3500 square feet of wood flooring....definitely NOT getting down on my hands and knees to clean or dry them. Haven't noticed streaks but that may be because my floors don't have a high shine.
Gee, can't BELIEVE the name of my floor cleaner got "edited" out!
