Have you tried permatex hand cleaner, it sucks, the one they sell at Autozone for one buck.
I tried some of that stuff. It's in a purple tube.
It was heavily
, and I mean heavily
advertised a few years ago as the new hi-tech way to clean your hands.
You don't use water. You just squirt a dab into your hand and rub your hands together.
It is some kind of polymer that sticks to the grime which then you rub off.
That's the way it's suppose to work. In reality you have to use 3x the recommended amount, and even then it doesn't work very well.
