Sugar plus warm jar equals fizzy pickle surprise.

Did my friend's "accidentally too hot" chili oil sell out after a bad review?

Yeah I saw a thread on a retro computing forum about this exact thing. Somebody said the old wax coatings and certain types of factory grime are alcohol soluble, so the 99% just moves the dirt around instead of lifting it. That water mix acts more like a rinse to carry it away. Makes total sense when you see that white film left behind.
