You believe wrong....Starsan and iodophor are about the same IF you are using distilled or pre-boiled water. If you are mixing with tap water, then the loss of effectiveness is quite rapid, for both of them. (The minerals in the water causes both to fade out in power and effectiveness quite rapidly.)
Iodophor works til the straw color fades....(a couple days in open air, longer in sealed containers.)
I keep a spray bottle filled with iodophor and distilled water...It stays effective in that sealed medium for a couple months...the color doesn't fade for quite awhile.
One thing a lot of us do is that when the color starts to fade in a bucket full of iodophor, we add a few drops until the straw color returns.
