I use a Zep product sold in Home Depot called Hardwood & Laminate Floor Cleaner. It leaves my floors very shiny and does a very good job of cleaning any marks, stains, etc. that may be on the floor. I use a cotton rag mop with it and it never leaves streaks on the floor. You can buy the small 32 oz. container and then refill it with the 1 gal. container they also sell.
I've had hardwood floor guys come work on my floors in the past and they've all mentioned how shiny the floor is and have asked what product I use. They all said it was a great product.
