Things You'll Need
Once you've removed the alcohol from a bottle you'd like to reuse, you must wash it to remove the smell. How easily the smell disappears depends on the bottle. Decorative or specialty bottles may contain small nooks and pockets where alcohol could stick. Depending on how much time has passed since the alcohol filled the bottle, the residue may have dried, making it more difficult to remove. Fortunately, alcohol comes off the surface with some scrubbing.
