Yes, I use Boraxo. It's the only thing that gets really grimy hands (from shop, cars, garden, etc) clean without tearing them to pieces. Most shops I've worked at also use Boraxo. It works as well or better than the more expensive pumice laced cream style hand soaps (like GoJo).
The one thing I lack at home are suitable dispensers. Right now I'm using a well labeled plastic squeeze bottle with the tip clipped big. Works pretty well. But a wall mount dispenser would be even better.
