This is our new un-du "VOC Compliant" formula that incorporates the only "all in one" removal system and continues to safely and quickly remove all self sticking and pressure sensitive sticker, tapes, labels and adhesives on contact without leaving behind any stains or greasy and oily messes. The only difference with the new un-du patent pending formula is that it will evaporate like the original un-du formula, but not as quickly. One of the biggest advantages of the new formula is that you will use less un-du to remove your stickers.
