Hi thadius856,
First off, thanks for your great work on the keezer front! I've referenced your posts numerous times during my current build.
Have you had any issues with using John Guest fittings on the gas side? The only other posts I've found about it are from people who are thinking...
Just tried the Oxyclean method on a bunch of different bottles including Sam Adams, Abita, Guinness, and Red Hook. Hot water and 4 scoops of Oxyclean per gallon got the labels 100% off in about 2-3 hours with no help on my part. I honestly didn't expect it to work that well!
