Have you ever bought a new stainless-steel kitchen utensil, only to find it has a sticky label attached? Even the most careful of peeling off the label will usually leave a horrible mess of glue/residue stuck to the utensil.
The simple solution is to just pour some olive oil over the residue area and let it soak in. After about 30 minutes, the glue should just rub off after a light scrub with hot water and dishwashing detergent.
And the best part about it? Completely food-safe, unlike some of the other alternative solutions out there!
