Removing masking, duct or scotch tape from walls is the simple part, but extracting the adhesive residue left cemented to the wall, not as easy. The adhesive left clinging to the wall requires a procedure that softens the glue so it wipes from the wall effortlessly. Attempting to remove the adhesive otherwise may result in damage to the wall or chips in the paint.
Turn a blow dryer to the hottest setting. Aim the nozzle at the tape residue on the wall. Heat the tape for 30 seconds to one minute.
Pick the tape residue from the wall with your fingernail or wedge a butter knife behind large pieces of adhesive stuck to the wall. Keep the butter knife as flush as possible with the wall to avoid gouging the surface.
Moisten a cloth with 1 tbsp white spirit. Wipe onto any remaining stubborn pieces of residue. Allow the mineral oil to loosen the tape for five minutes.
Wipe the mineral oil and the remaining tape from the wall with a damp rag. Dry the wall with a clean cloth.
