I love Frog Lube (tub) but it's so expensive.
The ingredients of Frog Lube are a secret BUT I'm pretty sure I know what's in it:
1. Hydrogenated palm and/or coconut oil. The hydrogenation serves as a preservative and a thickener by raising the melting temperature. You could use non-hydrogenated but it will be thinner and the shelf life will shorten to months instead of years before rancidity occurs. Refrigeration would extend shelf life in this case.
2. Undetermined amount of wintergreen oil (methyl salicylate.) (Color, smell, preservative.)
I have not tried this recipe yet but I will on one of my throw away guns first. These ingredients are pretty cheap compared to the cost of Frog Lube. And they measure up to the claim that Frog Lube is relatively non-toxic and could be eaten.
