I have a keg that had wlp 645 I just emptied, if I starsan the stainless and boil the rubber parts will it be purged of the nastiness that is white labs brett C? Can I put the keg back into regular rotation? I have a pack of wyeast Brett B I'd like to use in the keg but I don't want to cross contaminate with the C. Right now I'd feel safer using the keg for a session mild that is going to be killed within a month rather than a big beer I'm planning on aging for 1 year+. Any thoughts?
