Maybe a better idea would be some Mineral Oil or even some vegetable oil although the cooking oils could attract critters.
The Mineral Oil is generally a petroleum product. Very weak as a rule. Some of it is food grade like they use on cutting boards.
Maybe some bees wax or even furniture wax. Paraffin?
Lots of non-chemical, non-smelly choices out there
