With Ballistol you get a wart remover and possibly a tonic for irregularity! I thought this was about penetrating oil rather than something that stops hobby horses from squeaking but we goeth where the Wind listeth, do we not?
Well, I DID mention Kroil, but then again I'm not sure we can classify Kroil as a penetrating oil. I have also heard that Coca Cola is a great penetrant due to it's phosphoric acid content. It did not work for me, and talk about sticky residue! Since I quit drinking the stuff, I have not popped a single kidney stone. That's Coke, not Kroil.
