I have some hand sanitizer here that says it is 62% isopropanol alcohol (rubbing alcohol) and it burns nicely, but it is liquid in a pump bottle.

I guess the 65% alcohol sample you have not burning means people need to check their products like Sherpadog did, to make sure before trusting they will work.

I don't have any tiger balm salve around to try, but since it contains camphor, menthol, cajuput oil, mint oil and clove oil it might burn nicely.

Clove oil, the stuff for tooth aches, burns like lighter fluid does.
