Are there any tips or suggestions that I should be aware of using wood soap bowls? (Specifically the C&E one, at least for now). I usually load the brush off the soap, pretty dry, but ofcourse there is still a fair amount of water on the bowl, around the edges, and possibly under the puck inside the bowl. I try to let it airdry before putting the lid back on, but that doesn't always happen, and the inside is always dry by the time I use it again (either evaporates or absorbs I don't know). Is there anything I should do to make sure long term use of this wood with water will last? Or is the finish they put on it completely waterproof or something. Thanks
