I have a circa 1895 wing and gable home with yellow pine floors. The floors in all the rooms are bare where the original owners had a rug then the rest of the hardwood floors were painted brown around the rug. I would like to have all the paint removed so that the whole wood floor can be seen and then have the whole floor finished. There are remnants of a reddish stain under the brown paint so I know that part of the floors where stained. I have heard not to sand yellow pine floors. Stripping the paint sounds like a big project. What about the part of the floor that is bare? It needs to be cleaned before staining. Looking for advice and options. Pictures have been posted.
