Step 1: Cleaning the Bottle
To remove the paper from the bottle, soak it in warm, soapy water for about an hour. Then, scrub the paper away with either the rough side of a scrubber sponge or a scrubber brush. I would recommend not using a scrubber sponge once the paper is removed because the rough side causes the glue to bunch into hard-to-remove balls on the glass surface.
Use the isopropyl alcohol to remove the glue by pouring the isopropyl alcohol onto the glue and scrubbing with the brush.
To remove any smell that may be present in the bottle, pour some isopropyl alcohol into it and swirl it around briefly. Then, wash it out with water and allow it to dry fully (at least 4 hours upside down). I propped my bottle up using the bottom rack of the dishwasher.
