When I use my soaps, after I make the lather I typically leave the lid off until that night. I give the soap a chance to dry from the water I applied to it from my wet brush. However I noticed that when I do this with my MWF it dries and cracks. I'm sure you know what I mean if you use MWF.

Anyway, should I allow it to dry like this or is it better to leave a little moisture in there before I seal the container back up?
