A Quality and Effective Product
I have used this consistently for years. I like the fact that it is easy to use without a lot of foaming that forms in using some sanitizers. Does a terrific job without any residual off taste. No need for rinsing just allow to air dry.

Excellent low-foam, non-acid sanitizer
I normally use Star San, but needed a non-acid sanitizer for an anodized surface. I've found that it also works great in applications where bubbles are best avoided. It's all I put in my airlocks and blowoff containers now.

Good. No Foam
I like this iodine based IO Star 32 because the is very little foaming when I mix and use compared to StarSan. No foam means no foam is left behind on sanitized surfaces and cleaning is faster. I also like the bottle which has an internal measuring/separating feature to allow measuring up to 1 ounce in a separate part of bottle, so that makes measuring and pouring out that small amount much easier

Performed well for my use.
Performed well for my use. I have a fermentation device that can only be sanitized with this. I mainly use starsan. Overall good product, just another means to an end.

Simple and efficient!
In over 10 years of brewing, I've ONLY used concentrated iodine, primarily IO Star, to sanitize and clean my equipment. I've talked with folks who swear by other sanitation methods that require more labor, time, and money. I've never had an infected batch, so why would I switch?! I highly recommend this stuff!

Great product!
Diluted to the proper 25 ppm or less concentrations--just follow the on-bottle directions--this sanitizer has little to no scent on its own and a bit of pink color. This pink color comes from the actual iodine in the product and you may notice that it does TEMPORARILY stain surfaces it comes in contact with.The reason the staining is temporary is that iodine will sublime from solid phase to gaseous phase at room temperature. I use this in my airlocks and the pink color from the iodine is gone within a day and all equipment sanitized with this loses the pink color very quickly as well. This is perfect because you can sanitize things like your bottles and let them drip dry for a while and little to no iodine residue will exist as long as the bottles dry well!The only negative I can think of would be due to user misuse. For example, if you bottle your beer before the iodophor solution has dried, you have introduced iodine to your beer. This alone is not really a big problem, as it's perfectly safe in proper amounts, but be aware that the iodine can react with certain compounds in your beer and some percentage of people are extremely sensitive to the resulting compounds. I, personally, cannot taste iodine tainted foods/drinks, but those that do find them to taste absolutely terrible. This is also why you should never add iodized salt to your water for brewing.

Can this solution be used in combination with the Krausen Killer Carboy Washing System?
J O on Jan 11, 2016
BEST ANSWER: Yes, this would be a very good choice for this use! ( By contrast, the StarSan foams quite a bit, and would NOT be a good choice for this use. )
How long will a solution keep? And how do you know it's gone bad? I know with Star San it becomes cloudy, how about with this?
A shopper on Feb 12, 2018
BEST ANSWER: Iodine solutions don't keep as long as star san after mixing. Since the active ingredient is iodine, you can judge it's effectiveness by the color. As long as it has the amber/brown color, it is still effective. When the color fades, the iodine is gone (it will evaporate over a day or two).
I have some of this that has been sitting around for a while. Can I check it with a pH strip to see if it is still active? And if so, what should its reading be?
S T on Sep 9, 2016
BEST ANSWER: I don't think it would have changed but you should check straight with 5-star themselves.
