Un-Du is a SCRAPBOOKERS BEST FRIEND!!!

They used to advertise in every scrapping magazine years ago....not sure if they still do. Acid-free & photo safe.
You can use it to remove old photos from those magnetic albums too if you still have any left.
Does NOT leave a stain on a layout when using it to remove something. The adhesive on back of item will dry quickly allowing you to reposition it elsewhere if you want.
Don't panic, when you first apply it, the page will have a big wet spot...but it dries right up....and you will never know.
I had Xyron adhesive all over some photo edges once & it just got worse & got all over the photo & the page protector. Removed it all.
Also good for removing price stickers from glass.......
Often sold in scrapbooking aisle or stores.
Also found in hardware dept...or both.
Walmart carries it too.

It comes with a scraper tool attached to top of bottle. I tip bottle to let some liquid onto the tool, then I put my finger over the nozzle so more doesn't keep coming out while I scrape off the sticker. If I need more, just remove finger & let more un-du out. That's how I make the bottle last longer.
Odd....I googled & can't find a link to a manufacturers site. Just to TONS of reviews & stores that sell it.
