Time for me to eat some crow! Regarding
Used wine bottles
Soaking wine bottles in PBW and water for a couple of days is just as effective as baking and peeling off the labels. In fact, this method is cleaner since there is no need for solvent to remove the last bits of adhesive from the baked bottles. The Labelnator is still necessary, but I have learned to be more careful.
I find that doing a followup soak, after the label is mostly scraped off, will clean up about 90% of the bottles. I will need to scrub down the bottle with a Scotchbrite or Magic Eraser after the second soak, but the bottle is very clean after the second round of soaking.
