There is a product called Un-du which I have mentioned here before. It is available at Bunnings; it is very expensive for the small bottle you get and it evaporates in the blink of an eye if you leave the lid off. It is designed really for scrap-booking, so you can remove stickers and reuse them. I find it invaluable for removing the sort of labels that auctioneers like to stick all over everything, old price labels from books etc. For any paper-based sticky label, a few drops will penetrate down and undo the label, if there is any sticky residue left a few more drops on a tissue will remove it. I have used it on all sorts of surfaces - paper, leather, wood - and it does not leave marks, as ordinary "sticky stuff" removers tend to do, because they are oil based. I don't think it would penetrate the surface of the tape, you would have to lift a corner and squeeze it underneath, and then work along. I don't know what the stamps are worth but I don't know if it would be cost effective - did I mention it was very expensive? For anyone who may want to try it on regular labels, I would recommend NOT using the "tool" that comes with it as recommended in the instructions - in my experience it is impossible to squeeze just a few drops onto the tool and before you know it, your bottle is half empty. I squeeze out a few drops, spread it around with my finger to cover the label, leave it for just a few secs to penetrate fully, then if it requires more, add a few more drops. Much more cost effective this way. I see that Bunnings now sell a 118ml bottle, which would be much cheaper than the old 30ml one - must try and find it. Hard enough to find as it is. It IS available on Oz eBay but at greatly inflated prices.
