You count me as another fan of the Craftmeister Alkaline Brewery Wash. I run it in my fermentors for about 20 minutes using a keg and carboy washer, and they come out sparkling. I also let it sit in my tap lines for about 20 minutes after a keg kicks, and it really cleans them up nice. I always follow-up with a clean water, then Saniclean rinse.
The ABW is REALLY harsh on the hands, though. I now make sure that I am wearing gloves when I use it.
