E85 contamination

This is a result of letting my car sit for 4 months. The E85 absorbed moisture from the humid air through my gas tank vent. My car is kept in a garage but unfortunately it's always very humid here San Antonio. Which means there's a ton of moisture in the air. The car ran perfectly fine no hesitation or stuttering. This could've been avoided by treating my E85 every tank & with driving it more often. It was down for upgrades during those 4 months.
