I use Spic and Span when I can get it and very hot water. I squeeze the mop lightly on the heavier areas first then go back over. It's an old floor and as long as it's clean that's all that matters. With a history of 7 dogs and 3 adults walking on it every day, it just isn't as pretty as it used to be. Are we going to replace it. not in my lifetime. We put the new floor down in this home at old landlords request. Not doing it again.
