I want to add something here. Although I am not fully knowledgeable on how Oxyclean handles organic contaminants, an alkaline cleaner like Craftmeister or PBW will more readily kill any organic compounds (like bacteria). Actually the best alkaline cleaner is caustic but it is dangerous to use in a homebrewing environment and can cause burns if not handled and mixed properly. Given that, the two popular alkaline products do a good job with these organics. If you want to be more cost effective, find a dairy supply store near you like Tractor Supply and purchase the cleaner that is used on dairy equipment. This works very well and cleans up glassware and stainless steel nicely. I bought a 40 lb bucket of the stuff from a local supplier that sells and installs bulk milk tanks a couple years ago and use it to clean my bottles before competitions (I don't use glass carboys anymore). IIRC, I paid less than $50 for it and it will last me many years.
As a reminder, alkaline cleaners will not remove beer stone in kegs and fermenting vessels as beer stone is not organic. You need an acid wash to accomplish this.
