How to Get Labels Off Jars

Whether you are upcycling jam jars at home, preparing glass packaging for resale or cleaning jars for use in a commercial kitchen, removing labels from jars can be surprisingly tedious. The combination of paper backing and pressure-sensitive glue means many labels cling stubbornly to glass, leaving behind torn scraps and sticky residue. This guide explains how to get labels off jars cleanly and efficiently using safe methods suited to both domestic and professional use.

Why Jar Labels Are So Hard to Remove

Jar labels are designed to stay in place. Whether they are used for branding, nutritional information or product tracking, they need to remain stuck throughout the jar’s journey from filling to storage to sale. Most are made using paper or plastic with a strong adhesive that bonds well to the smooth, non-porous surface of glass. Over time, these adhesives dry and harden, especially if exposed to heat or sunlight. Attempting to peel them off dry often results in paper tearing and glue remaining on the surface.

Soaking in Warm Water and Washing-Up Liquid

One of the most effective and gentle methods to remove labels from jars is by soaking them in warm water. Fill a bowl or sink with warm water and add a good squeeze of washing-up liquid. Submerge the jars and leave them to soak for at least twenty minutes. The combination of heat and detergent helps weaken the adhesive and loosen the paper. After soaking, most labels will peel away easily with your fingers. Use a soft sponge or cloth to rub away any softened glue that remains on the glass.

Using Oil to Lift Sticky Residue

Even after the label is removed, the adhesive may leave a sticky patch on the jar. To get rid of this, apply a small amount of cooking oil, such as sunflower, olive or coconut oil, to the area. Let it sit for a few minutes, then rub in circular motions using a clean cloth or sponge. The oil breaks down the glue, making it easier to wipe away. This method is safe for glass and avoids using harsh chemicals. Once the adhesive is removed, wash the jar again with warm soapy water to remove any oily residue.

Bicarbonate of Soda for Tougher Jobs

If the label or glue has been on the jar for a long time, a paste made from bicarbonate of soda and oil can work wonders. Mix equal parts oil and bicarbonate into a thick paste, then apply it to the sticky area. Leave it for ten to fifteen minutes, then gently scrub with a cloth or sponge. The bicarbonate acts as a mild abrasive while the oil softens the glue. This is a popular method for cleaning glass jars in bulk, particularly when preparing them for reuse in a commercial or craft setting.

How to Remove Labels from Jars Without Soaking

If you are short on time or do not want to soak the jars, you can try applying heat directly using a hairdryer. Aim the heat at the label for twenty to thirty seconds to warm the adhesive, then try peeling from one corner. This can help the label come off in one piece, reducing the amount of glue left behind. Use oil or vinegar afterwards to clean any sticky residue. This method is useful in warehouse settings or kitchens where soaking is not practical.

Cleaning Glass Jars for Resale or Refilling

For businesses that refill or resell jars, label removal is part of the essential cleaning process. After removing the label and glue, jars should be washed in hot water and left to air dry. If they are being used in food production, check that the label removal method complies with hygiene standards. Avoid any strong-smelling substances unless you are certain they will be fully rinsed off. Consistency in label removal helps maintain a clean, professional look for your repackaged goods.

Avoiding Damage to Special Finishes

Some glass jars come with coloured coatings, printed designs or frosted finishes. When removing labels from these, it is important to avoid harsh scrubbing or strong solvents that could damage the surface. Stick to soaking and oil-based methods to protect the integrity of the jar. Always test a small area first if you are unsure how the surface will react.

Removing Labels in Bulk for Business Use

If you deal with hundreds of jars regularly, such as in catering or cosmetic production, label removal can become a time-consuming part of your workflow. In these cases, soaking jars in batches using large plastic tubs or industrial sinks can save time. After soaking, having a designated workstation with cloths, oil and cleaning materials can streamline the process. If sticky labels are used repeatedly on the same type of jar, consider switching to removable labels or applying them to tag-style holders instead.

Summary

Getting labels off jars can be a simple task with the right tools and techniques. From soaking in warm water to using oil or bicarbonate paste, there are effective ways to lift both the paper and the glue without damaging the glass. Whether you are cleaning jars for a home project or preparing packaging for resale, a clean label-free jar helps create a professional and reusable result. Taking the time to do it properly ensures better presentation, hygiene and usability for your jars.
