This isn't really what this thread is about, but here's my reasoning. Much of the chemicals in our daily lives which are supposed to be non toxic are actually harmful. Like someone said, mineral oil is an oestrogen, and perhaps even carcinogenic. Personally, I don't think there's ever a reason to put a petroleum product in your body. They're carcinogenic and wreak havoc on hormones. I have a sneaking suspicion that all these petroleum products are why breast cancer is through the roof these days and why so many women can't get pregnant. When I was kid, you could get a woman pregnant just by looking at her the wrong way, and now it takes a team of doctors.
Someone suggested PTFE. That's in the same category as mineral oil. It's supposed to be non toxic, but it's been linked to all kinds of health problems. Ballistol contains mildly toxic ingredients used in makeup and artificial flavorings, which has been banned in some countries. While I would much rather use ballistol than some other CLPs, it's not ideal.
More and more, I'm becoming convinced that all these "mildly toxic" substances in our environment are having a cumulative effect. When I was a kid, people hardly ever got sick, and now there's some new exotic autoimmune disease discovered every week. The only thing that's changed is that there are chemicals in everything we eat or put on our skin. Take antibacterial soap. When I was a kid, no one was worried about germs, and the only people who ever got fatty liver disease were hardcore alcoholics. Now you have kids getting it! And now they know why; antibacterial soap causes liver damage. The crazy thing is that people are still using it! In any halfway sane society, it would be banned, and here we are over a year past the study results and it's not even on the news.
Thus, I'm that guy who eats organic and uses all natural products as much as possible. But I spend a good deal of time shooting, handling, and cleaning guns; and I don't want to wear gloves every time I pick up a gun, so that's no solution. And I don't want to spend big bucks on frog lube or fireclean because I'm pretty well convinced I can come up with something better for less.
