Also did the google thing and found a bit more info which tell what it can do, but were talking about 70% stuff, but maybe over time the same thing will happen.

70% isopropyl alcohol works, nut not as well. The extra water forces the flame to expend energy vaporizing water, which is not compensated by energy liberated in combustion. Often the wick will become enriched in water as the alcohol burns away, leaving excess water behind. He net result is that the burner burns feebly and may give up the ghost entirely after a while. I have learned this by sad firsthand experience.
