Pour the mineral oil into the pan and add the beeswax. Melt over low heat just until the beeswax has completely dissolved, stirring as it melts. Once the mixture is blended, remove from heat. Allow to cool for a couple minutes so it's not too hot for the glass, then pour into the glass jar and allow to finish cooling completely. Add the lid, label it, then store in a cool location.
Use
Scoop some onto a smooth clean cloth or towel (not terry cloth). Wipe on clean wooden surface, adding more as you go. There will be some excess on the surface, and that's ok. Allow it to rest for about 30 minutes or overnight, then smooth the excess. Reapply weekly to protect wood.
