I see some white spots on my soap. Does that mean it's gone bad?
What you’re seeing is soda ash and it’s completely harmless. It can sometimes occur on the surface of the soap that’s exposed to carbon dioxide in the air. It will wash away with the first use. If you bought the soap as a gift, you can wipe the soda ash away with a damp paper towel. (Tip: Wear gloves so you don’t leave any fingerprints on the bar.)
