Remove Sticky Tack from walls by gently rolling the material from the edges into a cylinder. Use the cylinder to remove any remaining bits. The material adheres more tightly over time. Spraying the edges lightly with citrus cleanser helps release the adhesive without peeling the paint.
Over time, it is possible for the blue color of the adhesive to stain the wall. Using citrus stain remover helps eliminate the faint tint. Older paint is often porous, allowing the oils of the poster adhesive to soak into the wallboard. Eliminating the oil stain requires scrubbing the oil and paint away before repainting the wall. Prevent these stains by avoiding use on wallpaper, porous surfaces and porous brick.
