Review (3/5): High Sulfur works great
This soap is the highest sulfur content, but it dissolves fast. If you don’t take special care to keep it away from running water it will dissolve before your eyes. Know that, if you soap up whatever you’re working on and keep it away from running water you can 10 or so uses out of it and it’s gone; that is plenty of time for it to do its job. Make sure not to get this in your eyes or on silver jewelry, it burns and turns silver black.
