IO-Star Iodophor - Change in concentrations?

[DroneKeeper]

My bottle of IO-Star Iodophor shows to use 25ppm concentration and to simply air dry without rinsing. However, I see lots of references on here regarding a 12.5 ppm concentration is recommended but there is no instruction for that dilution on the bottle The only place I can find reference to that concentration is on their website in regards to CIP Sanitizing. Did this product change in recent years to recommend a 25ppm concentration but used to recommend less?

Don't sweat the concentration. As long as you can see the iodine color in the water pretty well, you're fine. Other than staining your plastic gear, I don't think there is a problem with over concentration. I typically use one ounce for 5 gallons.

That was what I have done so far as well (1 ounce to 5 gallons for 25ppm). I've seem some discussion that it needs to be rinsed at this concentration despite the bottle saying otherwise. Just trying to figure fact from opinion. I am assuming you aren't rinsing at this concentration correct?

You don't have to rinse at 25 ppm. Just let it drain and you're fine.

I was curious about this too so I looked it up on their website.

1 oz in 10 gallons (.6tsp/gal) = 12.5ppm
1 oz in 5 gallons (1.2tsp/gal) = 25ppm

I usually do 25ppm and don't rinse. I've never noticed an iodine flavor in the final product
