We bought a house last year that is 136 years old. There are two large sections of hardwood floor that are original. My girlfriend gave me this tip that makes them shine like a new penny. I take amonia and water and give them a good washing. I let that dry and then use Liquid Future Floor wax. A friend of ours is in the flooring business and eventhough the bottle says not to use it on wood floors, he says it will not harm them...I've been using the Future floor wax on my floor for almost 2 years now and my goodness are they beautiful. They're one of the first things a person notices. I also use the liquid floor wax on my painted stairs (they're painted high gloss black) and goodness do they shine as well). Neither the floor nor the stairs become slippery...just beautiful. Normally, I put at least two coats on letting each dry between coats for about 8-10 hours...that way when I do put my furniture back there aren't any scratches. I love this stuff!!!
