Iodophor sanitizer is a type of sanitizer containing iodine, typically used in food processing, dairy equipment, and healthcare settings for its broad-spectrum antimicrobial properties. It is effective against bacteria, viruses, fungi, and some protozoa. Iodophor sanitizers work by releasing iodine slowly to maintain a stable concentration for disinfection. They are commonly used in dilute solutions and are known for their effectiveness in cold water and hard water conditions.
