I cleaned 4 cases last weekend. I followed Charlies Papazian's instructions 1 cup ammonia for 5 gallons of water. I made a double batch. I have a kegger tub that holds 1.5 cases. I put the bottles in for an overnight soak, outside. Took three nights
In the morning, using rubber gloves, I lifted them out. I would say half the labels fell off the others wiped off. Bottles were; Sam Adams, Pete's Wicked Ale, Bud & Bud Light. After wiping them off I dropped them in another tub w/ just water to rinse most of the ammonia off. Later I used a jet bottle washer to thoroughly rinse.
This weekend I plan to jet wash again, sanitize, brush, and then bottle my continental pilsner.
