G'day, ive recently started brewing my own beer in kegs. I've gone through all the work with bottling and raised the bar a little for myself. I was looking at a tutorial on youtube about how to rinse, clean and sanatise your keg. And the guy on the video uses a product by the name of Star San to sanatise his equipment. I've looked it up and it contains a blend of phosphoric acid and dodecylbenzenesulfonic acid. I would like to know what kind of cleaners and sanatisers other fellow keggers use and where to buy them because im looking for a cheap method of doing this rather than the small expensive bottle alternatives.
