Final answer:
The iodine sanitizer solution needs to be in contact with the object being sanitized for 1 minute.
Step-by-step explanation:
The iodine sanitizer solution needs to be in contact with the object being sanitized for 1 minute. This is because iodine works by oxidizing cellular components and destabilizing the macromolecules, which takes some time to effectively sanitize the object. For example, when iodine is used as a tincture, it is recommended to let it sit for 1 minute to ensure proper disinfection.
