A little information on Un-du adhesive remover. Un-du safely removes all self-sticking stickers, tapes, labels and adhesives on contact without harming the your surface. It evaporate without leaving behind a stain and is safe on most all surfaces. I use it on photos and removing anything that I want to remove off my cards and scrapbook pages. This product is acid free and safe to use on all archival papers and card stock. It's flammable so be careful around heat sources and of course keep this away from children.
