Citrus all-purpose cleaner
Blu Tack is a type of adhesive clay that you can use to attach paper or light posters to walls. The Blu Tack will pull clean from most smooth and non-porous surfaces, but if you press Blu Tack on a textured wall or on wallpaper it might adhere to the surface and be hard to remove. The Blu Tack can also stick to the wall if you leave it there for a long time.
Spray a citrus-based all-purpose cleaner directly on the Blu Tack until it is completely soaked. Let it sit for 10 minutes to soften the Blu Tack.
Rub your hand over the Blu Tack to roll if off the wall.
Scrape any remaining Blu Tack off with the edge of plastic spoon. Use more citrus cleaner if the Blu Tack is hard to remove. Work until all of the Blu Tack is gone.
Spray the wall with the citrus cleaner and wipe it off with a paper towel to remove any residue.
Don’t put Blu Tack on porous surfaces such as brick.
