We tend to get messy with our hands, especially when working a job in mechanics or even something as simple as gardening. That fresh dirt smell won't seem to go away, or that dark black oil grease seems like it might be permanent. There is a great way to deal with this; the solution is likely just sitting in your kitchen. Can you guess what it is? Yes, salt. It works like a charm!
When washing your hands, pour a large amount of salt onto them and start scrubbing. This will add extra friction, and your hands will become cleaner than ever.
