I've been using Sodium Metabisulphite for all my sanitizing of my fermenter + my S/S Keg. Have heard that this is not that good and should be using Iodophor or something like that.
What does everyone recommend that will work well for plastic and stainless.
I use each Iodophor and Starsan interchangebly.
I don't like giving the little critters an even chance, so change from one to the other to keep them jumping to their doom.
Excuse my ignorance, but I was of the belief that star san is an acid cleaner? Therefore how can it be no-rinse? I have never used it, but by the comments here, I may start using it. Is it environmentally safe? Is it a concentrate? I have started using the brewcraft NRC powder, but it's pretty expensive. I use chlorine in my fermenters, because I know it's going to kill everything and it's cheap, but it's not environmentally safe and you can't use it for SS.
So have got my hands on some Star San and used the 1.5ml to 1 Litre as per Mike's answer. Pour it in shake it all about and 3 minutes later pour it out. I'm left with a stack of foam. Is this foam a concern do I need to get rid of it? I was making a yeast starter and was concerned that I would kill my yeast if i poured it in with this foam still in the vessel?
