Hi all, Hoping to get some recommendations for the following. In the house we just bought, it has hardwood floors throughout. They're in pretty good shape for being over 40 years old, but at some point a previous owner put some of those self-stick vinyl tiles just inside the front door. The staircase is about three feet inside the door and the tiles cover that space plus about an extra foot to the left of the stairs, so it's around 12 square feet of very old tile. Some of them are loose (I've pulled on the corners) and a couple of them are broken off, leaving behind dried up glue. Is there a product that will remove the glue without totally eating through the finish of the floor? The finish may be gone anyway, which might be why they stuck the tiles down in the first place, but I'm looking at options. Thanks for any input!
