Hello, being new with brush and soap. Is it best to keep the soap from not getting too wet, while not in use. Will soap go bad if it gets all wet and soggy. My instincts say yes. should I keep it covered or uncovered after it gets wet? Is it best to cut off a piece and use it and keep the rest fresh and cut a piece as I need it? I know I seen a post where it was grated like cheese. I like the sound of that, but before I start grating exspensive shaving soap, I would rather ask you guys. thanks
