LOL I have tried most of these suggestions. I have medium oak color floors, I've used actually, vinegar/water/alcohol mix, equal parts (I use this mix on my windows and mirrors, no streaks), my Shark Steamer which is what I really thought would work. It cleans them, just streaky. Pledge wood floor cleaner. The only thing that I haven't tried is to dry them right after they are cleaned, so I guess I'll have to try that. Right now, with the sun not shining on them, they look gorgeous since I cleaned them this morning. I'll just have to keep trying.
