I've finished a lot of my axe handles with sweat.
But, I have a mixture of mineral oil and beeswax that I use on a lot of my wood that gets wet or washed regularly (steak knives, wooden spoons/spatulas, and other sorts of wooden things).
I heat some mineral oil in a pot and start adding beeswax. When I get about 2:1 oil:wax, I let it cool. If its solid, reheat and add oil, If it's too liquidy, I add wax. I want it just about the consistency of honey when it is completely cool to room temp.
A little bit goes a long way and it is food safe.
