I have ordered MWF and the ceramic bowl. I noticed that the puck is smaller than the bowl. Does the puck stick in the bowl with some water? Do you grate it to get an edge to edge fit?
Do you guys let it dry out before putting the lid back on after use?
No. MWF loves water. You'll want to put the lid back on as soon as you're done. Using the soap for extended periods of time and keeping the puck moist will help give you great lather and make it easier to load.
