Susie: Thanks for sharing this tip! I've done this in the past and it really is a great help when the time comes to wash your hands after gardening! I kept a bar of soap in my basket of gardening tools on the deck for a long time and need to do it again! I would actually dig my nails into the soap, making sure it was deep beneath my nails ... it's so much easier than having to use a brush to scrub and scrub trying to remove the dirt beneath the nails!
