The real problem... Lets all get on the same page, glue or lables? Is everyone here an oxyclean sales rep? Why add anything $$$ just to soak off a paper label? Just plain old water soaks off labels. Hot, cold, doesn't matter. Heck, how many times over the years have we all reached into a cooler full of ice to grab a cold one that's been in there half the day, and the label slides right off?
I believe the REAL problem most people are looking to find an answer to, is removing the glue that's left behind. Still trying to figure that out myself. You need the right solvent to dissolve it so it washes away easily. I'm not going to sit there and scrub for hours. This is where the REAL problem lies. It stands to reason that different bottlers likely use different types of adhesive, so there will be no one-size-fits-all solution. The bottles I'm trying to clean from GLBC, water doesn't work on the glue. Neither did mineral spirits. I'll try veg oil next, and if needed, ammonia after that. Maybe it'll be a citrus based solvent. It really depends on the nature of the adhesive. Something out there will do the job. I'm not scrubbing!
