Baby oil is mineral oil. I have psoriasis and I put on baby oil at least once a day, sometimes several times a day. If it is so toxic, why would people be putting it on babies? Heck, if it is so toxic, why am I still alive? How can cooking oil be toxic either? I cook with cooking oil and then eat the food I cook with it. It may be something but hardly toxic. Let's see, baby oil, not toxic, doesn't short out and blow up stuff when it leaks. Water, one leak and you could have to buy a new rig. Cost of mineral oil versus a new rig. I don't think that is even close. lol Also, it doesn't have to be a "new" idea to work. Just thought it worth a mention. Dale :-) :-) -- I am only responsible for what I said ...
