I was reading in the book "How to Brew" that, after you wash your equipment to get it clean you can put your items in your oven and cook at 340F for an hour and this will sterilize your stuff. Obviously I wouldn't put plastic in there and would sanitize it using something else, and the stuff I did put in would sit in the oven while it heated to avoid thermal shock but this sounds like a really cheap way to ready the brewing equipment. Is this correct, or should I be using sanitizers on all of my items?
