For each method, remove as much of the label as possible first. An easy way to get the adhesive to release is to fill the jar with really hot water. Be careful when handling the jar and don’t burn yourself!
First Method: Olive Oil
Olive Oil is my favorite method because it’s eco-friendly and is super easy. Pour a couple drops of oil onto a paper towel and rub at the remaining residue from the label. Keep rubbing until all residue is gone. This should only take a minute or two. Make sure to wash your jar afterward to get the oil off. I just run mine through the dishwasher.
This method is actually a little faster than the olive oil but you have to deal with the fumes from the nail polish remover. (You can see here that I combat this issue with “cucumber melon” scented remover :) ) Pour the polish remover onto a paper towel or use the applicator if yours came with one. Scrub away at that label and adhesive and it will just slide right off. Quick and easy! Again, make sure to wash the jar afterwards.
These two methods are fail-proof. I have never had a jar label that I couldn’t remove using one of these two methods. Next time you are about to throw out a glass jar think of how easy it is to re-use it and try one of these methods. Let me know what you think.
