There are no expiration dates on various chemicals I have, such as the TechI Iodine and B-Ionic by EVS.
Does that mean that these items are good forever if kept is cool conditions ? If not how long does one keep them ?
They last a long time, if properly stored. I am sure the manufacture can put an expiration date on it, and FWIW, I will probably suggest you to use if a year after the date, and accuse the company for asking people to waste their money.
As long as there is no unusual precipation or color, I am sure they will last indefinitely.
