Thanks for the offer, I was thinking that I might try a really thin pipe cleaner or something. Needs to be thin enough to get in the bubble, but also have some kind of brush or bristles to remove the mould.

The sliver ones are thin, just a little thicker than cotton thread. Would you be wanting to poke something through the thickness of paper. If possible, if the bubble allowed?

How about an interdental brush, but extended in some way? It would certainly be fine enough and has a built-in brush at the end:

Well it's made no visible difference. It might have killed it, no way of knowing really, so looks like plan B is needed.

Would you settle for the mold not being on the card back. But sort of like dust in the bottom of the bubble?
As I can't see how you are going to catch it all. From a small area lift.
If the mold was "wet" or alive so to speak what about trying cat litter or rice to see if it would have drawn it out from the bubble to the card back ?
I'll send you some wires, as if you use the dental sticks you might need a longer length for manipulation.
The fabric from pledge fluffy dusters might have good grab quality if you could get a piece small enough inside.
Best of luck on whatever you decide .

Sorry i did not see this topic any sooner, judging from your picture i'm too late to warn you that UVC light is the most effective light to damage the blister and cause it to yellow https://www.usplastic.com/knowledgebase ... entkey=858
I have been working with UVC light to battle mildew on plants and while it kills the mildew and it's spores it does not remove it so you will have to agitate it to remove it from the cardback.

Thanks, appreciate it! I only put it under the light for 15 minutes as per the recommendations with the lamp, hopefully not enough to do any damage. I also covered the card with paper.

I had a thought. How about a very long, thin blade or knife? If you could insert it through the gap in the blister, you might be able to literally scrape off the mould and bring it back to the gap on the end of the blade. Brushing off the mould risks dislodging it and spreading it around inside the blister, but if it could be neatly retrieved back to the gap, you might be able to remove almost all of it from the blister.

Well attempt 1 has been pretty successful, before and after below :) I bought one of these from eBay:

https://www.ebay.co.uk/itm/333735464167

There was a small gap at the bottom of the bubble where the seal was weak, so I popped it in there and with much manouevering and patience managed to get most of it off. I have probably made the bubble lift slightly worse, but I would prefer that to a load of mould inside. Will have another go later.

What a difference, well done with your perseverance.
