I had this when we bought our home too. There is a bottle of cleaning solution that you can buy at Lowes (probably home dept too) I can't remember the name of it, it comes in a black jug. It has a I skull on it and it had "40" in the name. Anyway its a very strong cleaning solution but the smell is very mild, pour it on your floors with very hot water and take a deck scrubbing brush to it as it will take the stickiness and most of the stain up. to get rid of it completely you will have to sand and refinish. your floors.
Just remember to dry your floors quickly with a towel when finished. you don't want your floors absorbing that water.
Hope this helps! Good luck.
