I fill the wine bottle and plastic bottle with very hot water. Because the closeness in size, only a little hot water is needed for soaking. Paul M of Hong Kong agrees with Winston J of Seattle . The labels are pre-punched for binder filing. I've been homebrewing beer for over 5 years and the easiest way I remove labels from these is to let them soak in a solution of household ammonia for one to several days.
Ammonia is too, but as diluted above, comparably less so.
In either case, use gloves to handle the bottle and label when retreiving them. A simple wash in cool water removes the solution, and the label may be pressed between clean white paper towels touching the label, then newspaper and a weight to press the stack. No method is completely reliable, but primarily I soak the bottles in hot water with a dash of bleach. Some newer glues are unaffected by water but will melt enough to slide off the label after having been toasted with a blow-drier for five minutes. I'm sorry for my bad English, especially for explaining a complicating problem as removing of labels.
