How do you make wood floors less slippery & squeaky?

So last week my uncle dragged a bag of smelly garbage across the wood floow that leaked & left a reek.

I sprayed the floor with a can of lemon scented wood polish & steam-mopped it. Now the floor is squeaky clean; too squeaky, & a little slick, so slick you can't step on a mat or wear slippers or socks without falling on your ***.

We figured the floor would quiet down as it got dirty, but it still makes that squeegy-on-glass noise when you rub a hand or foot over it. One of my roommates thinks her washing the steam mop's cloth in Downy has something to do with it, another thinks it's the wood polish.
