ᐅ Oiled Wood Flooring Has Stains – Any Experiences?

Three years ago, I had engineered wood flooring installed over underfloor heating in my new build, which was initially treated with three coats of Osmo hardwax oil. By now, I have many ugly stains, especially in the kitchen and under the table. The flooring is surprisingly sensitive to (water) stains.

How can I restore the flooring? I would prefer not to sand it because the top layer only allows for one sanding. After just three years, that seems too soon.

Can I simply apply a new layer of oil over the stains? Or do I need to treat the stains first? The water stains are darker than the wood floor but not black or oxidized. The grease stains are also darker but without oxidation. So I have these wood-colored but darker spots all over the floor.

I hope someone here has experience with this. Thanks in advance!

Unfortunately, you can see streaks from the roller here and there. Now I'm thinking about applying another coat of hard wax oil. What do you think? Would that help with the streaks from rolling?
The professionals on the HGTV shows always use cloths, never rollers or brushes...

And with rags and oil, always keep in mind the risk of spontaneous combustion!
