I understand your mindset is much more scientist based on facts and studies.
Mine is much more common senses.
Stronger alcohol just means the mix of alcohol.
Regarding Mineral Oil, it is well shared fact that it does accumulate into your lungs till it does something bad.
I remind having read a story on a CNC forum about a guy suddenly having trouble breathing from day to tomorrow, he wasn’t old at all, like in his early forties as I remind.
He went for some medical checks and the results were pretty clear, he has oil based product stuck inside his lungs, like a small pocket of oil, went onto a surgery to remove it asap as the doctor said he had a few months left to live if he don’t remove it, after that he said he moved to flood cooling and wear a mask anytime he work in the shop lol.
I made a lot of researchs regarding filtering and health effects of manufacturing, honestly, I coudn’t find many studies, so I had to resort to read a lot of experiences of individual, some weren’t pretty, but most people are fine althought they know they are taking a risk. Genetics plays a big role too.
It’s up to each to do what they want, I would rather trust my common sense.
Regarding alcohol I would think that it’s less dangerous, but I woudn’t go as far as saying it’s good. It is still a poison.
