I've been running with Ocyclean as my primary cleaner for a while now. You pay half price for twice as much product when compared to PBW. Its a great cleaner and its very inexpensive. I've let it sit in my kegs before for up to a week with no problems. Anyone who isnt using it should give it a whirl.
