I didn't/haven't/won't/ put oil on my Escher but if I did how would I proceed to remove it?

I have an indeterminate stone which could be a Llyn Idwal or Tam O Shanter or even a Charnley and I'm getting itchy to see how it performs under mineral oil.

This far along in my experiments it is finishing as well as my B/G Escher just with water. The finishes are marvelously smooth shaving.

Lacking more experience, it is time consuming eliminating all the variables to be certain it is the stone and not another element affecting my results.

The natural stones recently acquired really drive home just how much they can vary in performance. Synthetics are repeatable and predictable. The naturals are an adventure.
