The glue left by tearing off the label can be removed by rubbing, pressing, scraping, soapy water and vinegar. You can use your fingers to roll the adhesive into a ball. The glue left by the label is not that strong. This method is very effective. Use your fingers to rub all the adhesive repeatedly with a little force.
You can use ordinary wipes or disinfectant wipes. Wipe away any remaining adhesive with a damp cloth until it no longer feels sticky to the touch. You may need to wait for the surface to dry before repeating several times to completely remove the adhesive.
