mineral oil?

What is the difference between food grade mineral oil you see at online butcher supply stores and mineral oil you buy at Walgreens labeled mineral oil "intestinal lubricant"? I want to coat the inside of my tinned cast iron meat grinder head to prevent it from rusting. I have used the stuff from Walgreens on my plates and knifes and it works quite well.

I do the same. Don't know the difference if there is one. I figure if its safe to pour in your gullet its safe on the grinder.

That's what I use too- - the stuff from the drug store. Over time, vegetable oils get sticky or go rancid. Mineral oil doesn't. ...plus, as you say, it's certified for internal use.

Thanks guys! I just wanted to make sure there was no difference so I don't cause harm to my cast iron tinned head of my grinder. I will be using the drugstore stuff on the head of my grinder.

The only parts that you need to protect from rust are the surfaces that are not coated with tin. The only vegatable oil I ever buy is olive oil.
