Thanks to whomever suggested the Bestine instead of Un-du. I wish I could remember your name so I could give you the credit!! The Bestine is working WONDERFULLY! I was so crushed when it was announced that Un-du wouldn't be made or sold anymore, and I stocked up on it! I ran out of it last week while un-mounting all my wooden stamps. I had un-mounted about 1500 of my 10,000+ wooden stamps, and was so upset that my Undu finally ran out. I have tried so many other removers...the Goo-Gone, Sticker-Lifter, Elmer's Sticky Out, Scotch's Sticker & Marker Remover, and several others, and NOTHING works. Then I read on here where somebody stated that the Bestine Solvent & Thinner worked the same as Un-du and had the same ingredients. I rushed out and bought a can of it....there is no ingredients listed on the can, so I can't vouch for that, but I can tell you it works just like Un-du!! I'm so happy!! I have spent all day un-mounting again!! WOOHOO!! I'm so happy! Did I say that already??? HA HA!! Anyway....just wanted to say thanks to that person, and let everyone know that Bestine really does work!! I'll definitely be going out and buying more so I can "stock up" just in case something happens and it "disappears" like the Un-du!!!
