Love to reuse glass bottles but not keen on using the chemicals to get rid of the sticky mess after removing the label?
A simple solution is to place a piece of paper towel over the sticky area, secure it with 2 rubber bands (avoid banding the sticky area itself) and soak it with pure lemon essential oil.
Lay the bottle on its side, paper towel side down, and let it sit for an hour or so. You ought to be able to easily wipe off the sticky residue, using the paper towel and a bit more lemon oil if needed to finish cleaning it. Wash the jar as usual.
Bonus: It smells great while it’s working!
