How do you effectively remove sticky labels from jars?

To effectively remove sticky labels from jars, you can soak the jar in warm, soapy water to loosen the adhesive. Then, use a scrubbing pad or sponge to gently rub off the label residue. Alternatively, you can use a mixture of equal parts baking soda and cooking oil to create a paste, apply it to the label, let it sit for a few minutes, and then scrub it off.
