Certain kinds of Hand Sanitizers are pretty runny and certain kinds of burner trays are pretty holey, so that combo may not work too well. I know Sterno will not run at all, so it does work well in like Wilesco's very holey burners!
I'll definitely be looking to pick up a bottle of 75% Hand Sanitizer soon, and see how it works for me in some of my engines!?!?
