Oak floor refinishing advice needed
The oak floors I need advice about are in my deceased parents' 1950s, split-level house. I don't know how they were originally finished (maybe shellac?), but I think my mother used to have them waxed. The flooring in the closets looks beautiful. Everywhere else, the wood feels smooth, but there are variations in color (especially between areas where furniture was and wasn't), maybe some water marks, and some black spots (they kind of look like burn marks, but I doubt that's what they are). I really like the look of the flooring in the closets and I'm pretty sure polyurethane was never used. I've been experimenting here and there with Wood Preen and with fine steel wool. The Wood Preen didn't seem to improve the appearance, though it did take up dirt -- but maybe I used it too sparingly. The steel wool improved the look. Advice welcome. Thx.
