Will this soap fit into any of your bamboo soap dishes?
Yes it fits in style 2 and 3!
What is the most effective way to use this for washing dishes?
Use the lather from the soap with an eco-sponge or a kitchen brush to wash dishes!
Can you grate and use this in a dishwasher?
Yes you can. Although I would just spread it around the bottom of the dishwasher instead of putting it in the dispenser.
