3M mounting tape has proven to be a spectacular tool for bonding two items together. The concept is rather simple: just peel the tape cover and stick it to a surface, then peel the tape cover on the opposite side of the tape and press another object to it. The bond created is reliable and will stay as long as needed. When it comes to removing it, however, the 3M mounting tape's strength is not its best characteristic.
Lift one corner of the 3M mounting tape with your fingernail. Do not use a spatula or metal blade as this can cause scratching or damage to the bonded surface.
Cut a piece of fishing string that is about one foot in length. This will provide adequate working area for the tape.
Wrap about six inches of fishing string around between both pointer fingers.
Pull gently on the fishing string beneath the lifted corner of the 3M mounting tape. Pull the fishing string back and forth in a sawing motion.
Work the fishing string through to the opposite end of the 3M tape section, lifting it gently from the surface until it has completely lifted off.
Apply Goo Gone to the sticky residue left on the surface. Work the Goo Gone into the sticky residue with an old rag. Repeat this step until all of the 3M mounting tape glue is removed.
