I've always used iodophor, and I've always loved the stuff. Due to the popularity of Star-San on this site, I picked up a small bottle of it. I just tried to sanitize my carboy with it. Now my carboy is full of bubbles that will not go away. What the crud. Now most of the carboy is sitting there partially filled with persistent foam bubbles, while the rest is exposed to the air. What do I do?
