I use recycled beer bottles (still with label and part of the alu foil seal) and immerse them overnight in cold water. The next morning I add hot water, wait an hour or so and then go to work: scrap off the stubborn labels and the tin foil with a knife, rub them down with steel wool and finally ‘polish’ them with a regular household detergent. Any tips on how this work can be done in a more efficient way; what attacks/dissolves the glue under the foil coated labels? Thanks for any tips!er... I talk about the outside of the bottle... the inside is no problem once I am finished with the outside, usually they are pretty clean. Sterilising is the last step of my operations before drying and filling.thanks, yes, I have tried immersing them in near boiling water, leave them until the water is tepid and then wash... still the bloody stickers won't come off easily. They are foil covered and prevent the water from reaching the glue!
