Ultimate Survival WetFire Tinder burns wet or dry, it's odourless and non-toxic. It very easy to use simply scrape the surface of a cube and create a small pile of shavings and ignite with your firesteel.
If it's particularly wet you may need to use a whole cube but there's 8 in a pack so there plenty for more fires.
This stuff really does what the picture says. It will float and stay alight on water.
