First items I am going to work through are the few smoky binders. So what I did was take the cards out of the binders, throw the binders and the pages which were in rougher shape, take some paper towel, spray the paper towel with febreeze, let it dry, then put the cards and paper towel in a large sealed rubbermaid bin for about a week.
So how did the cards turn out? Not bad. The smell is either gone or very close to it. The febreeze smell stayed for a day or two, but once it went, I am having a hard time telling if I am smelling a very faint smoky smell, or old cardboard smell, so that's a good sign.
One thing it couldn't fix is that the top row of cards, because the top of the cards are exposed n the binder, all the cards in that row have a bit of colouring on the cards at the top.
I am guessing there may be more tomorrow...
If you are still reading, then we have some bonus content for you. in addition to the above big pile, I recently was able to complete a box for box trade - 800 count boxes, so about 700 cards going each way - with TCDB user seppola10, who is a fellow Canadian, who is out in Alberta.
