I have a bottle of Iodophor I bought at my LHBS a couple years ago. Its no name brand. Is it still good or should I throw it out? Could the active ingredients have evaporated?
If it's not diluted, it's fine. Colour = function. Active ingredients in iodophor can't evaporate, since the ingredient is iodine
I bought a big bottle of the stuff back in 1996 and I'm just about out now. I have had no problems with mine
