I have sustained serious staining damage to
(a) wood floor from file cabinets (b) TWO table tops, from this stuff.

The stains are so bad, I can' get them out with anything
I've tried: several brands of wood cleaners - even bleach.
(the bleach ruined adjacent wood; didn't removed the stain.)
Not even Jasco got it out. Nor did steel or bronze wool or even light
hand sanding.

Question: Is this stain removable, period?

Or do I have to have the surface refinished?

If so, how deep would the refinisher have to go to get
stain out?

Consult a woodworker or vendors of speciality timber
or cabinet-making tools. Your main problem is that
stains penetrate under the top surface of finished
wood, thus usually requiring sanding to remove the
whole top surface, then refinishing all (smoothing,
sealing, coating etc.) Finishing methods vary, e.g. a
wood floor coating needs to be much harder than the
finish on a table top.

Stick-on protectors for wood should be stuck to the objects
(e.g. filing cabinets) and not to the wood.
