Q: How do I bring back the shine in hardwood floor that has been under carpet for a very long time? Tips for restoring wood floors under carpet?
A: If this is a polyurethane coating, first give the floor a good cleaning with a suitable cleaner for this type of finish such as Poloplaz Hardwood floor cleaner: www.poloplaz.com. This will help remove any dulling contaminants. If this is not sufficient, then a professional buff and re-coat should do the job. If this is a wax finish, a product such as Dura Seal Renovator will clean up the floors nicely.
