Videne is an iodine based antiseptic and although I've used it to sterilise bottles in the past without any problems at all I'm not convinced about its effectiveness as you really need a chlorine based product.
Videne will not
clean anything but I do know that iodine its used on farm to sterilise bulk milk tanks.
I've just gone back to VWP from Antiformin, which I seemed to use up quite quickly
. A 400 gram pot of VWP will make 120 gallons of sterilising liquid, for about a fiver thats a bargain despite all the bloody rinsing.
