According to the text on my bottle of Iodophor, they recommend
a 25ppm solution for sanitizing beverage containers. 2 minute contact time, invert and drip dry. no need to rinse.
Since iodine sublimates, I don't see how the concentration of the solution would change it from a no-rinse to a rinse... you might need to wait longer for the sublimation to complete, but.....edit: I actually only use a 12.5ppm solution for bottles.
