I mixed up a fresh batch of StarSan with distilled water and after a couple days in my bucket with the lid on it smells slightly of sulphur. It's not strong. pH checks fine. it does not remain in or on anything sanitized with it.
Why does it smell at all? It never has before and I leave it in my bucket for days.
