I'm a new dad and recently I've been doing a lot of DIY projects that involve metals, which are greased in petroleum based lubricants. I clean my hands thoroughly with hand and dish soap after the work, but I still smell like petroleum. All petroleum based products warn against skin contact on the labels. I am hesitant to touch my baby when I smell like machine oil for her safety. How do I clean my hands thoroughly?
I have a white collar job, and my DIY projects are infrequent enough that its feasible to let mom handle the child care exclusively for a few hours after my repair jobs. However, I'm sure plenty of auto-mechanics and shop workers have had this problem so I'd like to know how they solve it.
