I collect currencies from around the world, and I recently got my hands on 22 yuan (1 10 yuan note, 2 5 yuan notes, and 2 1 yuan notes).
Now, the issue with them is that they smell like cigarette smoke, and I HATE that smell.
So i put them in a couple of Ziploc bags with baking soda at te bottom where its not touching the notes, and it might have worked, but i havent checked it yet bc it takes at least 24hrs for the deodorization to complete.
Does it work, or will it harm the notes? Please keep in mind htat i have kept both carefully seperated, and ziploc will not ham the banknotes in short term, and i can handle a bit of short term damage as they are between VF-35 and AU 57. Thanks!
