I think my Institut Karité puck might be spoiling-it's starting to turn beige (from pure white) and has developed a slight ammonia like scent??? I was shaving with it the other day and I noticed the lather scent was off-like skunky; seemed fine two days prior. I've had this soap for almost exactly 1 year and have maybe 20-30 shaves in it, and always let it dry before I store it in a tin. Anyone else have this happen? I'm gonna keep it out in the air for a couple days and see what develops but I think it might be cashed.
