    What would happen if the card's contacts got corroded over time by urine? Would the images on the card be completely inaccessible and unreadable, or would they be accessible but have color corruption?

    I'm from an electronics background, so I'll throw my two cents in on the issue. The acidity of urine is incredibly low, and contact materials on electronic devices are designed to be fairly corrosion resistant, most memory cards I've used have what appears to be an ENiG finish on the contacts (emersion nickel-gold). The nickel gold contacts will not corrode... If they do oxidize slightly, inserting into a reader a time or two would be enough to remove the oxide layer and make contact. Memory is memory, urine will not affect digital memory... I wouldn't try it, but you can likely submerge the card in liquid, remove it, let it dry for a few days and it will still be usable. As long as it is dry when powered on internally, there should be no adverse effects on the electronics

    If the contacts (only) get corroded, that won't affect the memory in the card. Trying to offload the images through corroded contact might corrupt the images, but only the offloaded image. The original should not be affected.

    If the contacts cannot be cleaned enough to allow offloading, anyone competent I'm electronics could be able to transfer the board to another card case and solder it to the new cases' contacts.

    The card may have been still wet when it was inserted in the computer's memory card slot... I didn't realize it may have had pee on it until I had already inserted it into the computer, downloaded the images, and removed it again... The images downloaded with no trouble, but I wonder if they might be corrupted...?

    The original images are still on the card; I only copied them to the computer (I didn't remove them from the card). But I did use my computer's image-viewing program to view the images while they were still on the card, before I offloaded them. Do you think that could have corrupted the original images in the card as well as the copies that were offloaded?

    I seriously doubt the images on the card have been corrupted.

    If you got the files off of the card and were able to open them without issue, they are not corrupted.

    Does anyone else feel like this thread is a troll? lmao :eyebrows:

    I've run a couple through a washer, with oxygen bleach. Images were fine. Don't recommend it, but they seem to be a lot tougher than the manufacturers warrant.
