I looked around and found a lot of blogs promoting peroxide, but, the FDA sites on sanitizing do not list it as an approved method. I did find this article which cites a real study which bloggers apparently ran with and made assumptions about. The takeaway here is that peroxide may sanitize depending on concentration and freshness), as may vinegar, but they often take a 30 minute soak to do so.
