Anyway, I have a batch on the go at the moment which I want to bottle, and I had a load of used bottles from which to remove labels and clean. I soaked all the bottles (and they are from a number of different breweries), and on some the labels just fell off, and the remaining glue was easily removed using hot water and a small scrubbing brush. However, the bottles from Adnams proved to be a total nightmare. They are plastic, and peel off OK but left a really sticky residue. I tried, in this order...
- IPA (not the beer - Isopropyl Alcohol)
- Brake and clutch cleaner.
- MEK (Metyl ethyl ketone - this usually shifts anything)
The petrol finally did the trick! Using a cloth and plenty of petrol, the glue dissolved quite quickly, and a quick wash in detergent finished them off. Use gloves for this - not latex as this dissolves in petrol - use nitrile gloves.
