This topic brought back memories from an unrelated area of my past. Years ago I was an avid home brewer and wine maker, and needed to recycle bottles with labels. I used a product called Straight-A Label Remover. 2tbsp/gal hot water and soak overnight. Even the most stubborn label would have sluffed off of its own weight by morning! Never was sure what was in it, but but it had that slick feel. Maybe highly ionic or something.
