I've used Murpy's oil for years and years and my floors are about 70 years old. Recently I started to use the Bona system. It's like Swiffer, but I was told when we put in a new(which is not really new, but recycled) hardwood floor in the kitchen that it's the only thing the flooring company recommends. Now I use it on all the floors and I'm very pleased. It's quick and easy and does a good job. I'm neurotic about clean floors. :)
