Stain removal is all about speed and technique. Here's the proven method for tackling sticky residue effectively.
Carefully peel off as much of the sticker as possible. The remaining residue is what needs cleaning.
Coat the sticky residue with cooking oil, peanut butter, or olive oil. Let it sit for 5-10 minutes to break down the adhesive.
Use a plastic scraper or your fingernail to gently lift the residue. Most should come off easily.
Dampen a cloth with rubbing alcohol and wipe away any remaining residue and oil.
Wash the area with dish soap and water to remove any oily residue. Dry thoroughly.
