I pulled up all the carpet in my bedroom, and some areas in the hardwood floor is darker then some other places. What can I do to make the floor bright again?
Sand it down and refinish it (stain, polyurethane). You can rent a machine and do it yourself or pay someone to do it. You could also put a throw rug over it if you can't refinish it.
The best option is to have it refinished. You can do this yourself or have it done. It will be sanded down to bare wood, stained if desired, then 3+ coats of polyurethane will be applied. This will make the floors look like new, and protect them for a long time. Good luck.
