In reply to slab_happy:
Okay, weird copy-and-paste error there. A more legible version:
50g shea butter
2 tablespoons olive oil
1 teaspoon (approx) beeswax pellets
optional: 40 drops of essential oils (I use roughly equal amounts of tea tree, clove and myrrh, which gives you something mildly antiseptic and analgesic for hands shredded by grit, and does seem to speed up skin healing a bit)
Melt the beeswax and shea butter in a bain marie (saucepan in a bigger saucepan of water), add the olive oil and essential oils, pour it into an old jar or tin and leave it to set.
It's thick and greasy but not quite as solid as Climb On. But you'd just need to tweak the ratios (bit more beeswax, less olive oil, etc.) if you wanted to get it more like that.
N.B. Don't use essential oils if you have cats -- they have very fragile livers and essential oils can poison them if they end up on their fur, get licked off, etc.
