Do not wash ethanol from gasoline ! Do not use additives!
Folks,
The only solution to ethanol in fuel is to avoid it. This has been reported many times over the past years. Ethanol blends are - in nearly all instances - not allowed in our aircraft engines that are STCd or TCd for autogas. You can not remove all the ethanol from an E10 blend, the resulting fuel is likely sub-octane and not a legal fuel, and you must also dispose of the resulting highly corrosive water/ethanol mixture.
You will find two articles on the subject of 'ethanol washing' here:

Urge the EAA and AOPA leadership to strongly support autogas as the only replacement for leaded Avgas that will power nearly all sport aircraft.
Urge your congressmen and legislators to repeal the RFS ethanol mandates in EISA 2007 that have resulted in ethanol adulterating our nation's fuel supply.
DO NOT USE AN ETHANOL BLEND IN AN AIRCRAFT ENGINE, PERIOD.
