- Peel off as much of the label as you can.
- With warm, soapy water, wash and scrub the outside of the plastic jar. Soak it if necessary until you can get all the paper of the label off. Use a washcloth and scrub till the only thing left is the sticky adhesive underneath.
- Use a dry washcloth and pour a little bit of mineral oil onto it. Rub over the sticky adhesive until it is all gone. It may take a bit of rubbing, but be patient and it will come off.
- Wash with warm, soapy water again to remove the mineral oil and dry with a soft towel.
Mineral oil can also work to remove stickers from wood. Just peel off as much of the label as you can, and skip step #2. It will take quite a bit of rubbing with a soft cloth, but it will come off and be good as new without damaging your wood.
