You guys probably know this already but I haven't seen it posted anywhere.
If you're going to work on your ride where your hands will be getting dirty/greasy, before you start, rub a small amount of liquid dish soap or some of that waterless hand soap on your hands, especially under your nails.
When you go to wash up, the dirt should come right off.
