I am careful of handling petroleum products, always use gloves.
The reason is, I had cancer and though they can't say definitely they said it could have come from using solvents. I read about that theory while researching my cancer. I used to wash a lot of car parts in solvent,Working at Union 76 in high school.
I lost 1 1/2 years of my life fighting cancer and they say it's going to come back.

Soooo I use gloves when handling ' chemicals'
But that is just me.
