We slid a box with new bedroom dresser across the room and there was a staple on the bottom of the box we did not know about. Looks like it put a long tiny dent into the floor rather than a gouges. It's pretty minor but bugs me since we are just moving in and the floors are very good shape. I read you can use heat from an iron to push the wood dented out and remove the dent. Has anyone had luck with this method?
