I keep meaning to come back to this thread...
Acetone did the trick, but it wasn't a pretty process. As best I can describe it, acetone "melts" the coating rather than dissolving it. You're not going to be able to just wipe on/wipe off - it takes some effort. Start at the back of the saw with a soaked paper towel and wipe towards the front of the blade. Flip the towel over, throw away and repeat. If you use a circular motion, you're just creating more work for yourself.
I threw my used rags in the fire pit and burned them immediately. Not sure if acetone has combustion issues like linseed oil, but decided to err on the side of caution and not throw them in the regular trash.
