Yes you can clean your hardwood floors using Pine Sol. But you need to dilute the Pine Sol in a gallon of water.
Take 1/4 cup of Pine Sol and add it to a gallon of water to mop the floors with.
Be sure to not leave any puddles and soak up any water or cleaning solution and dry the floors as good as you can because leaving water on the hardwood floors could crack or warp the hardwood floors.
If you have some stubborn stains on the hardwood floors you can pour a little straight Pine Sol on the hardwood floor and then scrub it off and then mop up and dry the hardwood floor.
