I swear by Holloway House as I have hard wood floors throughout the living level of our house.
Holloway products can be found at some Walgreens, and at hardware stores.
I use their floor wash, then the Quick Shine to give floors a nice shimmer.
Between washings, I also use their Quick Fix to eliminate spills, light scratches. These also work wonderfully on tiles and linoleum, making them look like glass (if they're not too warn).
