Discussion about the Korg PolySix synthesizer

Technically, you'd need something basic to neutralize the acid.
Alcohol is a good thing to clean an area and dissolve solids and wash
them away.  Of course, rubbing alcohol is acidic (ph 5.5).  If you
really wanted to neutralize the acid, a solution of baking soda and
purified water soaking on it would help.  Of course, after letting it
soak for a while, you'd want to wash it all off nicely.  I'd use
purified water for this.  Let it dry for a day before applying power.
