Step 3: Soak Your Bottles and Scrub Off the Labels
Now you’ll want to soak the bottles for a while (maybe half an hour to an hour) before you start trying to scrub the labels off, and you’ll want to soak them in hot water to help dissolve the adhesive. (While soaking, you can move on to step 4.) There’s not much to this step; just elbow grease and patience. I found it worked better to work on the label from the bottom up and to move back and forth, scraping it off evenly with the rough backside of the sponge. Not only does it come off in larger chunks, meaning less clean-up, but it also seems to pull the adhesive off better.
