Are you looking to remove the cup and grain dig out in pic 1, remove the scratches and gauges or remove the gray and dirt in the others?

Regarding pic one, If you want to level the surface you will loose the patina as the process will require cutting into the wood by sanding until even.

Regarding the scratches and gauges same as above.

If they have been refinished there isn't much you can do short of refinishing to remove the mold (gray). The finish has sealed in the mold so you will need to strip/sand to get to the issue to correct.

If you like the overall look I would start by several deep cleanings and was/oil removing. then assess the floor.

As for the spill sand very precisely to remove the high spots to level taking care not to break through the finish. you could then spot finish.

The last pic is a problem all around. I would pull up the whole floor if I could and carefully and reassembly to break up the line. I hate when repairs like that are made.

We weren't really looking to sand down until all of the grain and issues were gone.

We'd love it if they weren't finished with urethane, just waxed, and we could just clean the hell out of them and then wax them. But since they are probably urethaned, is there anything that can be done other than a full refinish with sanding, etc...?

How/what would you use to "deep clean"?

I suspect we're just screwed, live with what we've got or turn it into a huge job.
