If I am left handed why do my nails get dirtier on my right hand when I am wrenching on my car?

Question

This happens all the time. I mean they are vastly dirtier.

Answer 1

you probably hold dirty parts with your right hand and use a clean wrench with your left.

Answer 2

your left hand is on the clean tool and your right hand is propping up yourself or leaning on it and taking all the dirty stuff out or off so therefore it gets dirtier....maybe thats why if not sounds good!

Answer 3

if you are braceing with your right hand on a dirty under carriage, it will be dirtier, the tool in your left is probably clean
