After finding a version of homemade diffuser oil that calls for mineral oil found at the drug store, I had a light bulb go off in my head. We have several bamboo cutting boards that I use mineral oil on from time to time. The bottle I have is from Bed, Bath, and Beyond’s kitchen section. I wondered if I had paid a premium for essentially the same thing – it is $0.75/oz at BB&B compared to $0.28/oz at the drug store. After a little research, everything I read said that the mineral oil from the laxative section is the same as that from the kitchen section. So yes, I had paid a premium originally, but not anymore.
I also read a couple of recommendations to add a little beeswax to the mineral oil to give the cutting boards a little more protection. The ratio I saw was 80% mineral oil/20% beeswax. I had some beeswax left over from other homemade concoctions, so I tossed some in my double boiler with the mineral oil. Once it was melted, I transferred the mixture to a mason jar. It solidified somewhat, but it is still the consistency of room-temperature butter. I was reminded of a product I saw at Cook’s Warehouse called Bee’s Oil that I had considered buying. Now I’m glad I didn’t.
