1. Spread a spoonful of peanut butter over the offending label. You don't have to go crazy–a nice, thin layer of peanut butter should do just fine.
2. Allow the peanut butter to sit for at least 10 minutes. If your label is particularly stubborn, let it sit overnight.
3. Dip a washcloth in warm water and scrub gently at the label. It should rub right off!
4. Remove any excess peanut butter with a sponge dipped in soap and water.
Tip: If you have a glossy or large label, you may find that your label doesn't come completely off in the center. If this happens to you, peel off as much of the label as you can and spread peanut butter over the label remnants. Allow it to sit overnight once again and then wipe clean.
