Yes, Mineral spirits, or wd40 and a ROS works very well.
I have used WD40 myself.
A lot of that surface rust may wipe off with the WD40.
After that I would use the finest grit sand paper I think I could get away with.
I upgraded my stamp steel table saw wings to cast iron last year. One was perfect, but the other was rusted pretty bad and pitted a little. After soaking off all I could I still had to use a coarse roloc pad to get the really bad rust, then worked up to 400 grit sand paper. Wing is flat, and better than the old stamped steel.
Typically though, I will wet sand with the WD40 and 320 to 600 sand paper on my ROS.
That wing was the first time I had ever used such an aggressive grind to clean a cast iron surface. And I was not at all sure it would work out ok.
First photo is after the wing soaked in WD40 over night and hit with a wire brush.

Here I am about done with the Roloc pad

And here I had been using the ROS to finish it up.

The left side wing was the rusty one.
