  • storage jar



  • Combine the beeswax and grapeseed oil in a microwave safe container and stir. (It is easiest to use a mason jar that you will also store the oil in.)
  • Heat in the microwave on LOW in 30 second intervals, stirring in between, until the beeswax in melted.
  • Pour the oil into a storage jar and cover. It will solidify as it cools.
  • Apply to clean cast iron cookware as needed. Wipe out excess and heat to smoking to season surfaces.


Be very careful heating beeswax; it is very flammable and must be watched carefully.
If you are using a pan to melt the beeswax, you will need to wash it out immediately.  Once the beeswax starts to harden it is difficult to remove.
Only use a thin layer to season your cookware.
