When I purchased my new band saw table last year it arrived with a
beautiful steel table.

Now it has stained due to the processing of green wood for turning.
It is not etched, just stained, mostly by green maple.

I tried mineral spirits and steel wool with limited success.

What about very fine emery cloth and oil?

Anybody have any suggestions?

Simple Green, Fantastic, Spray Nine, etc, and a green scrubby (like for
pots and pans) and elbow grease. Same thing for your lathe bed. Dry off
and apply wd-40, wax or what used to be called top cote. Don't remember
new name. And if you think that maple stains try cherry :-) I use wd-40
on the lathe bed, but top cote on the bandsaw table.
