I bought an electric chain saw and following instructions I added
bar and chain oil. Between cuts I set it down on the sawdust on
the bluestone. Then when sweeping up I found an oil spot at each
place I set it down. I certainly won't do this again, but the
immediate problem is how to clean off the stains. I did some
Googling. I got a variety of suggestions. Does anyone have some
firsthand experience as to which of these actually work?

I know from experience what'll work because just today I had to
wipe some spilled oil (Watco teak oil) from slate. Just used
ordinary paint thinner, and it worked fine. Any equivalent solvent
will work (naphtha, turpentine, etc.) Don't use acetone or lacquer
thinner--overkill.

I don't think slate is as porous as bluestone. This all soaked in
right away.

I'd still try solvent. You may still have to use one of those other
methods of attack you found, but it will definitely not hurt to try to
sop up some of the oil with paint thinner or equivalent.
