IO Star

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._x000D__x000D_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!_x000D__x000D_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._x000D__x000D_Use this stuff right and it's the ideal sanitizer! I gain my insights from my chemistry degree.

Since this is based on iodine if you leave it in to long it will stain your buckets and equipment. Some got on my linoleum floor and stained it yellow. Works great otherwise.

Never had a problem with minimum dilution and 2 minute contact time. No foam, drains easily, and leaves no flavors or odors in beer. Always sanitizes extremely well. Highly recommended.

I like that it doesn't foam, but it doesn't last as long as star san.

When used properly this is really good stuff. I'd recommend rinsing thoroughly after using though just to be safe you aren't imparting any flavors. Good product.

I love this. The IO star, I feel is the best on the market. Low foaming works in coldwater. It also hasa low contact time. If you dont have this get it.

The only thing is that this stuff stains like crazy, just about everything it touches. I'm not sure how long this stuff stays sanitary, too. As in, I don't think that you can keep it in a bucket and use it two weeks later.

wont put a thing in my equipment without using this first

Just started brewing and I have to say that Io Star was a good so far. I have noticed that some of my equipment have stained a bit. I haven't noticed any off set flavors in my beer and I'm happy that I only have to use so little of it to sanitize.

No infections since using this, it kills everything. I use it as directed, diluting it, and applying it, and don't have long term staining problems. It's good that it doesn't foam up like Star San.

IO star works well but if you aren't careful it can stain. So I've gone back to using Star San and PBW. I still use the IO star on occasion and it works well.

I have used a few products to sanitize and have found the IO Star to be the best. Some sanitizers you have to worry about it foaming if you work too fast. This doesn't foam and only needs a one minute contact time. Great product and I recommend it to all my fellow brewers.

I like to use Iodine sometimes, to kill off things that Star San doesn't. I've had success killing mold and stray yeast with it. If you measure properly (it takes a very small amount) it wont stain and doesn't require rinsing.

If you mix it correctly it wont stain your equipment. But if you use too much, which is easy because all you need is 1/10 of an ounce which is hard to measure, it will stain. Its an economical and effective sanitizer.

I got a dropper and add 3 ml to 1 gallon to get a good sanitizer that I discard after using. At that dilution it doesn't stain, and it sanitizes with a minute of contact._x000D_It can work with hard water, which affects star san.

If you make it right it wont stain. Use three mili-liters per gallon. I use a dropper to get that little amount and mix it up, and use it that day, then spill it out. I give it 2 minutes contact time, then empty with no rinsing.

I make a 1 gallon solution and clean everything, not just my better bottles and buckets. Just fill and shake and pour out. 2 minutes later it's ready to use. I use both this and Star San, just to alternate in case there is something that one doesn't kill, the other one will.

I alternate this with Star San, just to make sure I kill everything. It doesn't foam like Star San and it won't stain if you diluete it according to the "no rinse" directions.

Very easy brew. Tasted a bite lighter than expected, but very good overall.

Easy to use and no foam. Just give it a chance to dry off before bottling. Make sure you follow the directions on the bottle about dilution. If it's over concentrated it can stain and you are wasting the product. I keep the mixed solution in a glass jug between uses._x000D_

I used to use this iodophor sanitizer because it is cheaper than Star San, but after switching to Star San I would never go back. The one thing iodophors have going for them is that they are better on stainless steel and copper than star san, so if you are worried about that and sanitize a lot of SS this may be something to get. Also, Star San is something you can miz up in a bottle and keep around for a week or 2 when you want to measure OG or rack your beer.

I tried this and StarSan and while both seem to work (no infections either way), I prefer Star San because of the IO Star staining issue. This is less expensive so it does have its advantages.

Not only did this sanitizer stain the majority of my plastic equipment yellow, but it imparted a chemical flavor to any beer I brewed with fewer than 3oz of hops. I followed all directions, and even went so far as to rinse off my equipment after sanitation. I�?���m hoping that I can use PBW to clean most of my equipment, but I will more than likely have to replace all my tubing. In total, I now also have 5 batches of beer with a chemical overtone. I started using this because it was cheaper than 1-Step, but I consider this a great error.

Got this by mistake once. It works but to my knowledge you should not dump this down your drains. For that reason I do not recommend this product.
