The last backpack trip we went on, we took our new stainless steel water bottles, and treated with iodine as we usually do. (Yes, I know they're not lightweight!) The surprising thing is that the water did not seem to have the usual yucky flavor of iodine that we had in our old Lexan and Nalgene plastic bottles. Anyone have an explanation for this?

I'm assuming it's not that the steel inactivates the iodine, or they'd have a warning on iodine water treatment products. I've pretty much decided to take my stainless steel bottle again this week, just for the more pleasant taste.
