Removing sticky labels from glass jars can be a hassle, but using shortening from your pantry offers an effective solution. The science behind this method lies in the nonpolar nature of both the adhesive and the shortening, which allows the oil to penetrate and break down the glue. To use this method, apply a small amount of shortening on the label, let it sit for 15 to 20 minutes, and then scrape off the label with a plastic scraper or credit card. If needed, wash the jar with warm, soapy water afterward. While shortening is ideal, other vegetable oils like olive or coconut oil can also work, though they may require more attention. This technique is especially valuable for those who frequently shop at thrift stores, as it encourages the upcycling of glass jars, helping to reduce the 12 million tonnes of glass produced annually in the US, of which only 3 million tonnes are recycled.
