I have harwood floors throughout the first floor of my house. We usually have to clean and polish every three years. Go to Lowe's or Home Depot and get a hardwood floor cleaner by Bruce's Hardwood Flooring. It does a great job. If your floor has a lot of scratches and scuffs you may have to rub a little, but it does not require too much elbow grease. After you finish cleaning, also get some of the Bruce Poly, and apply. This usually will take about 24 hours drying time, but well worth. When you finish your flooring should look great, similiar to a freshly cleaned basketball court.
Like I stated, this method usually last about every three years before having to re-apply, and clean-up in between the every three year maintenance usually takes a sponge mop with standard cleaning or warm water.
