My current recipe is equal parts water,tallow, soap mix ( 2 parts fels naptha 1 party glycerin saddle soap, 1 part beeswax), and a table spoon or two of eucalyptus oil. I boil the water add the tallow take of heat, mix in my soap and oil stir until everything is dissolved and keep stirring until it starts to harden a bit. When all said and done it has the consistency of saddle soap. I add the eucalyptus to give a pleasant smell and it will deter vermin from chewing on the item.
