I just bought one of those Listerine pocket breath sprays and noticed it says "caution flammable." So obviously I had to see how well it would work as a a fire starting aid. Well, a few sprays in one spot and it lights right up. Seems to have a fairly high alcohol content. Just one more pocket item that could be useful in a pinch.

Another good choice is hand sanitizer.

It's a flammable gel. Relatively cheap. Good day-to-day use in germy environments.

Alcohol pads ane they are more useful.
