Help! Bought some cork squares at Staples and they came with these sticky tabs to put them on the walls. Well needless to say the tabs don't really stick to the cork but i can't get them off the walls. I've used fingernails, putty knives, you name it but they leave a residue. Is there a product that will take them off? (I have a matte paint on the walls). Thanks!Hmmmm, we're pretty sure we've had a similar issue with that sticky putty that everyone used to hang posters up with in dorm rooms. We've heard that vodka has great de-sticking powers but don't know how it would do on a porous wall.
