Nail brushes seem to be made for delicate pinkies, so they don’t work on real working-person grime. In my local grocery store recently, I found a brush that does. Though not designed for hands, it’s stiff, big, and tough, and it has a beefy handle that can hook over a shower rod or shop sink. It’s called the Libman Small Scrub Brush and is about 2 in. wide and 4 in. long. It’s big enough to do the job on grimy hands, though it’s not for those delicate pinkies.
