Charlie is right, you can extract the ethanol with water. Best practice 
would be multiple small washings to reduce it to a negligible level, but 
octane would suffer. Also, your price of auto fuel just went up, because you 
are sending some down the drain.

Basically there is a partition coefficient for alcohol between gasoline and 
water.  Each time you add water, x% moves to the water.

Getting it out is simple; just add water. Then shake. Then sump the
water. But you wouldn't want to use the result in any engine except a
rotary; the octane just went down several points.  Some of the octane
enhancers are replaced by alcohol when it's in the mix.
